There is no compliant way of connecting those type of lights unless you use a junction box and take a 4.0 cpc from it. Also, running a single 1.5 mm cpc is also not compliant. 526.8 refers to the cores of sheathed cables being enclosed as required by 526.5, it makes no mention for the purpose of the conductor and the reference to 526.5 is the methods contained in that Regulation for the enclosure not whether it is a live conductor or not. See 543.1.1 whereby the cpc is no longer an integral part of the cable as the sheath has been removed. The cpc should be enclosed or mechanically protected. Very good Video though :)
Oi oi Mainline. I have to say that I find, as I get older and the alcohol abuse takes its toll, that it's getting harder to recall the do's and don'ts of the big brown book. That's not the case so much on design where one can take some time to ensure it's all thought about and checked properly, but more so on situations like this where we're faced with something unexpected that wasn't undertaken with any care or competence in the first place, and it's now up to us to sort something out on-the-fly without pulling down the ceiling. You're right of course that this isn't an ideal or compliant solution... and that it's difficult to implement such. These sort of faults require some thinking around there on the ground to ensure the customer isn't going to end up paying through the nose for a load of decorative repair, and so we can show some test data on paper that indicates some kind of improvement to how the last idiot had left it. I do wish I'd had 4mm on the van, but I don't know any other way we could have uncocked the unearthed downlights, switch and fan iso without some dirty great holes knocked in the place.
Showers usually regulate temperature by adjusting water flow, so setting ( other than a high/low switch) won't usually make a difference to current draw
Two masters at work….. I have been in the industry 39 years had a lot of apprentices in that time ….. all apprentices will learn from you both instead of telling people YOU NEED A £1.200 hilti drill to work as an electrician or side cutters worth £80 ….. you both keep it real and honest 👍👍👍👩🚀 David👩🚀Nigel 🚀
In regards to the current draw of the shower, I thought most electric showers do pull the full current regardless of temperature set and control the temperature by restricting the flow through the heater.
There's no diversity for the likes of showers, so the circuit design should reflect the rating of the thing. I may be talking out of my arse here, but that wouldn't be the first time.
The two earth terminals on sockets is designed for high-integrity earthing. Normal is supposed to both be connected into the same terminal, but it doesn't really matter that much.

0:32 "Jefferies Tubes" About 30 years ago, a new design for some of the equipment used at power stations was being trialled at the power station my dad worked at. At the time, he was one of the most senior instrument techs, and was tasked with writing a preliminary maintenance document before submission to the CEGB and then distrobution to other stations. There was a large air-feed pipe which had been bought off the shelf, so had no CEGB designation as such, and so he HAD to apply some kind of reference in the manual. He chose "Jefferies Tubes", as part of the maintenece was to crawl up the pipe to make a visual inspection of some sensors, and this seemed to resonante with the TV show theme of crawling through murky passages. This was submitted to the CEGB and while some edits were made, the name Jefferies Tubes survived - There must not have been any Star Trek fans at "the board". For several decades, the manuals for this equipment, and anything like it had a formal part number so that you could order "Jefferies Tubes". Fucking outrageous.
It’s always the same! I see it all the time. One of my favourite sayings to people is “The last people to be doing building work is builders!” Kitchen fitters, Bathroom fitters and plumbers are just are just as bad! I’ve carried out a few EICRs recently and the problem with most of them is poor workmanship from other trades. If a property has had a new kitchen, Bathroom or extension its a warning sign and the first place i start looking for the faults!!!!! I fix some things on EICRs, i also re-label boards as there always hand written or stock stickers (BG normally). Great video
Absolutely - the number of times we've come across a bad kitchen, extension, bathroom etc. only to be told the electrical mess was down to a third party. The question of "Did they give you a certificate for the electrical work?" is often answered by "No, they were a bathroom fitter, not an electrician." - Well, yes, but they've done the electrical work, so them not being an electrician isn't some kind of excuse that makes it all okay!
@@dsesuk That’s always my next question and a measure of the standard of contractor, “Did you get any paperwork?” The answer is always no! But fixing this stuff is paying my mortgage!!
My dad was a market gardener and a lot of greenhouses. 3kw heaters plugged in some. As a kid I was often changing plugs burned out and also sockets (I was about 10yrs if that) Damp environment caused corrosion and resistance. I had a trusting dad lol Used to do all the mechanical work on his vans from very early teens if that 😂 Now my sister has a dog swimming pool with 2x 18kv heaters 2 1.5kw pumps etc and a toxic chlorine atmosphere so done for this. It kills industrial dehumidifiers of which there is 4 + 2 back ups in constant rotation. Mainly fan seizures. Bush barings. People don’t think about this
One view of putting two CPCs in the same hole is that if they're twisted together (which OK they weren't here) then at least you retain some continuity of the earth loop if they come loose.
I hope those wooden joist at 13:33 are for show and not structural as that looks like the one on the right has a heafty crack in it in the stressed side. Great video Dave & Nigel. Have to say the logic of cutting the earth is astonishing. Glad you didn’t say it’s a “DIYer” as that’s getting a bit overused on some other channels. Installation Comments on existing installation “Very Good” 😂
Just wasted an hour and a half of my holiday watching this. Excellent and different as usual. How they get away with such awful installations. Good practical advice to fix some of the bodges.
You guys are in the wrong game! It has just occurred to me that Dave is a dead-ringer for Greg Davis, you buoys should be in comedy! Very entertaining. 😂
With it being a tncs did they run a seperate 10mm earth out there as there are extraneous parts ( copper pipes etc) or was it a 10mm armoured or did they rod it. Cheers
Im one of those c-units that puts both legs of an RFC in one CPC terminal. I have a weird internal mindset that if i connect them both together, i can say its good. If im relying the manufacturers link to connect the CPC's - it just doesnt sit right. You may have seen the 'deco' (not Scolmore) range at Homebase. They dont link the cpc on a twin socket. So for peace of mind / ocd, i like to have my ring CPCs in the same terminal, as my screw is keeping them together - no reliance on a third party. I tend to use the other CPC terminal for the backbox connection. That said i do sleeve them individually with 2mm sleeve. Sincerely A Cunit.
I came across an installation by an electrician (not a builder) where there were two electric cookers and an electric shower on the same circuit so of course it tripped when they were all in use at the same time.
Those integral gu10 downlights can be used as class 2 fittings according to the manufacturer. The information is hidden on the frequently asked question on the integral led website. I had to change a load of old mr16 fittings feed in 2 core flex and these where the only fitting I could find that where class 2. The earth is there to cover all specs. Fittings are ok but terminal enclosure are a bit rubbish. Your content is great like the way you you explain your thought process on how to deal with poor installations.
That's handy to know. I don't see why there's an earth anyway - if the cabling is terminated properly then you have double insulation throughout. Why even bring the metalwork into the electrical system?
Hi david you know the 3 pole c40 mcb in this video, is it still the same as a 60898 single pole mcb, apart from it cuts the live and neutral, Dose it matter which terminals on the device you use for the lives and neutral or can it be any, and dose it matter which way the supply or load connects to it top or bottom And if it exceeds 40 amp for a certain amount of time it trips Never seen these so interested to know how it actually works Thanks
I got caught out by Regulation 543.1.1 last week when I ran a 1.5 mm cable under the skirting board between two sockets where CPC continuity was absent. BS 7671 says I should have used a 4 mm cable, or at least 2.5 with mechanical protection. The skirting board provides at least as much mechanical protection as the sheath of a twin & earth cable, so I'm still considering my options before going back to the job to replace it.
I must admit Charles, I had forgotten about 543.1.1 when faced with this out on site. It's hard to remember all the caveats and requirements of the ol' brown book and just as hard to find where they are if you have the buggering thing right there with you.
That set the bar high for great entertaining watch on a Sunday morning I feel your frustrations😡. Tell Nigel his current hair style does not conform with regulations 😂
Jesus, I'm not more than a humble computer engineer, who enjoys watching electricians content. However, even *I* spat my tea out in shock, the second you mentioned that 10.8kW shower hooked up to a 40amp breaker, then remembered the entire 'rental' CU being covered by nothing more than a 40amp up stream!.... Slightly proud that my Ohm's law was up to snuff to calculate it to 47amp as well as you :D That CU in the garage was mind blowing as well. Very good find, and as usual, a top grade video 🤟
If you used Ohms law to calculate the current, then you did it wrong. The relationship between voltage, current and power is *not* Ohms Law. Ohms Law is the relationship between voltage, current and resistance.
I'm always surprised when electricians talk about " if the shower was run on very hot it would draw the full current!" In my experience, when a shower is turned on it ALWAYS runs at its full current. If you put your clamp meter on the line and turn the temperature control down to cold it just means that due to the speed of the water entering and leaving the unit, it doesn't have time to heat the water sufficiently. On tje hot position it does. So the current draw is constant. Particularly on a cheaper shower unit. There are a few premium end products that can regulate the current but these are few and far between!
I speak from clamp meter testing of my own appliance, but I accept it won't be the same across all makes and models. It's rather a moot point anyway as you don't build diversity into a shower, the circuit design is to the rating given regardless of whether it *might* pull less in practice. Here, someone has neglected to put any thought into what was supplying the building and what else was in use, and they've plumped for the most powerful shower they could find for some bizarre reason.
I recently moved into a council flat and it's been rewired this year with a chint dual rcd board why are people still putting in dual rcd boards just why
Never understood that builders work is usually need to be inspected by building control.so why dont they also inspect electrical work. Even if they just ask for certs and back ground check the spark
So far they've been pretty good. Heavier than the old fibreglass steps, but jolly useful when you need that bit of extra height such as accessing attics!
@@dsesuk that’s why I got them i only have a SWB Caddy so need things to be multi-functional where possible… but have to agree they’re brilliant steps and I didn’t wanna fork out for the little giants Got them for £180 from toolstation
A couple of comments Dave, I have family your end of the country and am recommending you. When I was an apprentice electrical engineer in the 80s having to keep moving otherwise id be earth tagged 😂 My boss was great. He had a lot of annoying sayings that I have heard myself repeating over the last 25 years. Took a while before this materialised 🤣 If it doesn’t look right it’s wrong. No ifs no buts was one of many and has applied to everything I have ever done and served me well. Listen to your gut feeling is another Buy well but once and look after your tools and they will look after you. What I love is you haven’t got your head up your arse. Don’t condemn things that pass everything to the regs at the time of instillation. Seen c1 on this?? One question I had to retire due to Crohn’s and it’s nasty relatives that decided to move in such as arthritis, Ankylosing Spondylitis, Primary sclerosing cholangitis (PSC) liver failure btw. Osteoporosis plus more. Had Crohn’s all my life and used to have a bucket in van no-one touched and throwing up into a bucket up a ladder. Took a year longer to pass my C&G due to hospital at the time in 80s. Recently found out I have ADHD which answers a lot. Explains when my boss was deducting my wages every time I was late and I ended up owing him?? 🤣 He then gave up. I always did my hours as time blindness works both ends of the day. I also waffle on a tangent?? My question is, when you retire, no longer registered, can’t legally wire your own house??? Do you get an electrician to do the work? Not touching anything as it’s naughty to do so. Or Fuck them, I can do this safer and tidier than most other electricians. Fuck the rules, I’ve kept up to date on regs etc. hmmmm🤔 One more thing, NICEIC approved electritian in my father in law’s old house. Full gut premiss and full rewire. I was fixing a gas leak (that I shouldn’t have been doing but he couldn’t get anyone)gas and heating off 3 days now in winter and he’s in his 80s) in the attic for him, put hand down and got a belt off a red and black? I repositioned myself getting another 3 belts off different live cables?? Not insulated and shouldn’t have been there anyway as a full rewire?? He was selling so I did the gentlemany thing, taped it up, 5 in total??? Fixed a leak off a dead leg gas pipe they had caught with a screw but took a while to actually leak, and fckd off. No I didn’t test as it was going to be a can of worms, told him to contact previous electrician, un available, had accident? Died??? After he chased for a couple of months? Why is it doing favours for family always ends up a pain in the ass. I got a friend to check after. I had already done a drop test and would never usually do this for anyone bar my own house. As far as electrical What is legality doing your own and immediate family? Also same for industrial 3ph for my sister’s unit. All tested etc no money exchanged. And nothing dodgy bar not registered with niceic, nappit etc
I've used that before Gino including on my own home where the shower and EV charger share the same circuit (shower has priority), but what would we load share the shower with here? The only other circuit we could share it with would perhaps be the cooker, but that wouldn't be a convenient solution and on it's own the 10.8kW unit blew the demand.
The chint boards usually use a smaller sized mcb. Normally supplied with a flexible link from the RCD or Main Switch to the first MCB then the bus bar just connects the MCB’S together. If fitted an rcbo next to the main switch you don’t need the flexible link. Still hard to get the lid on though. Great video as always 👍
Perfect for a Sunday morning with another bloody cold, thanks for that. As beefy as that car charger socket looked, are we honestly believing that they have fitted anything other than a standard socket in there?
Get well soon Oli. As for the BG socket, well time will tell. We've put a couple in now, so if we get called back to one that's melted you'll be sure to hear of it here!
Thanks Kev. There are many Class 2 integrated examples, but it was GU10 cans I was referring to. I don't like integrated downlights - too hard to put right when they fail!
Whoever bodged-up these circuits also forgot to calculate and allow for losses in the run of the armoured cable from the barn conversion to the little house, I'm thinking?
One thing I don't get is that these breakers won't trip at In. So a 40 amp type b won't start tripping untill about 56A according to figure A4 page 417 brown book appx 3. That shower draws 46.95 Amps. So how is it trippin?
It's not just the shower - and remember that the shower has its own B40 which is not tripping, but the MCB back at the house is also powering the sockets, lights, heaters, cooker and everything else. What perhaps didn't come across in the video, although it was mentioned, was that when we subjected it to stress we'd also switched on other appliances to simulate how the people who live there would be using it. Add in a panel heater, the cooker simmering a pot of water, some lighting etc., and even then the MCB might not trip in short order, but it does heat up and pops off eventually.
Wow, I've never seen a lot that's this foul-mouthed but also this professional at the same time. Love it! Are there many electricians like this in the UK?
Once again I'm glad I didn't have anything in my mouth at your shout outs. Gagging on a ****. As Nick would say "oh dear oh dear". I had a lot of hot birds on my face this arvo. Cheers
The shower load is constant, temp is regulated through what is essentially a mixer tap. There's no 10kw dimmer in there. Cracking vid though! Love the technical educational stuff!
There is no compliant way of connecting those type of lights unless you use a junction box and take a 4.0 cpc from it.

You're right of course that this isn't an ideal or compliant solution... and that it's difficult to implement such. These sort of faults require some thinking around there on the ground to ensure the customer isn't going to end up paying through the nose for a load of decorative repair, and so we can show some test data on paper that indicates some kind of improvement to how the last idiot had left it.

Showers usually regulate temperature by adjusting water flow, so setting ( other than a high/low switch) won't usually make a difference to current draw
My thoughts exactly ( unless you only have it on max cold?)
This one is actually one of the few that has a loose thermostatic control, but it's only got relays on the board to turn the heater on/off.

I agree, in most cases a 4mm is required for a separate shared CPC, and it also usually seems overkill.
I must admit Charles, I had forgotten about 543.1.1 when faced with this out on site. It's hard to remember all the caveats and requirements of the ol' brown book and just as hard to find where they are if you have the buggering thing right there with you.
Nigel's Spock ears are fu**ing brilliant. 😂😂😂
Just a note to say the budget chintz consumer units were sold by CEF in 2020... then faced out.
That set the bar high for great entertaining watch on a Sunday morning I feel your frustrations😡. Tell Nigel his current hair style does not conform with regulations 😂
Jesus, I'm not more than a humble computer engineer, who enjoys watching electricians content. However, even *I* spat my tea out in shock, the second you mentioned that 10.8kW shower hooked up to a 40amp breaker, then remembered the entire 'rental' CU being covered by nothing more than a 40amp up stream!.... Slightly proud that my Ohm's law was up to snuff to calculate it to 47amp as well as you :D
That CU in the garage was mind blowing as well.
Very good find, and as usual, a top grade video 🤟
If you used Ohms law to calculate the current, then you did it wrong.
The relationship between voltage, current and power is *not* Ohms Law.
Ohms Law is the relationship between voltage, current and resistance.
Another fantastic video well worth the wait. Its horrific to see the state of the installation and the fairy tale of an EICR
The occupants could have at least made their beds, now you had to see some ghastly stains on the sheets.
Nice work fellas. Loving the magic of cinena
I'm always surprised when electricians talk about " if the shower was run on very hot it would draw the full current!" In my experience, when a shower is turned on it ALWAYS runs at its full current. If you put your clamp meter on the line and turn the temperature control down to cold it just means that due to the speed of the water entering and leaving the unit, it doesn't have time to heat the water sufficiently. On tje hot position it does. So the current draw is constant. Particularly on a cheaper shower unit.
There are a few premium end products that can regulate the current but these are few and far between!
I speak from clamp meter testing of my own appliance, but I accept it won't be the same across all makes and models. It's rather a moot point anyway as you don't build diversity into a shower, the circuit design is to the rating given regardless of whether it *might* pull less in practice. Here, someone has neglected to put any thought into what was supplying the building and what else was in use, and they've plumped for the most powerful shower they could find for some bizarre reason.
@@dsesuk you are a wise and most powerful electrian. 🙌
Another great video. Hilarious and worth the wait
JCC V50 are IP rated and class II.
I recently moved into a council flat and it's been rewired this year with a chint dual rcd board why are people still putting in dual rcd boards just why
OK this is the best universe yet!!!!!!!!!!!!!!!!!!!!!!!!! 2:45 Hopefully the ship doesn't crash?..........
Never understood that builders work is usually need to be inspected by building control.so why dont they also inspect electrical work. Even if they just ask for certs and back ground check the spark
I’ve got those steps have you found (like I did…😅) that because the rear steps are so narrow that they’re not the most stable?
So far they've been pretty good. Heavier than the old fibreglass steps, but jolly useful when you need that bit of extra height such as accessing attics!
@@dsesuk that’s why I got them i only have a SWB Caddy so need things to be multi-functional where possible… but have to agree they’re brilliant steps and I didn’t wanna fork out for the little giants
Got them for £180 from toolstation
Great work guys!😊😊
That's a brave landlord with no credit meter in place on that little house
I'm only 2 minutes in and I'm frikin dying! Thanks for the videos
FFS that really made me laugh!!! Lol “spunk gargler” RLMAO - David, you are mental!!!!!!!
A couple of comments Dave, I have family your end of the country and am recommending you.
When I was an apprentice electrical engineer in the 80s having to keep moving otherwise id be earth tagged 😂
My boss was great. He had a lot of annoying sayings that I have heard myself repeating over the last 25 years. Took a while before this materialised 🤣
If it doesn’t look right it’s wrong. No ifs no buts was one of many and has applied to everything I have ever done and served me well.
Listen to your gut feeling is another
Buy well but once and look after your tools and they will look after you.
What I love is you haven’t got your head up your arse. Don’t condemn things that pass everything to the regs at the time of instillation. Seen c1 on this??
One question
I had to retire due to Crohn’s and it’s nasty relatives that decided to move in such as arthritis, Ankylosing Spondylitis, Primary sclerosing cholangitis (PSC) liver failure btw. Osteoporosis plus more.
Had Crohn’s all my life and used to have a bucket in van no-one touched and throwing up into a bucket up a ladder. Took a year longer to pass my C&G due to hospital at the time in 80s.
Recently found out I have ADHD which answers a lot. Explains when my boss was deducting my wages every time I was late and I ended up owing him?? 🤣
He then gave up. I always did my hours as time blindness works both ends of the day. I also waffle on a tangent??
My question is, when you retire, no longer registered, can’t legally wire your own house???
Do you get an electrician to do the work?
Not touching anything as it’s naughty to do so.
Or
Fuck them, I can do this safer and tidier than most other electricians. Fuck the rules, I’ve kept up to date on regs etc.
hmmmm🤔
One more thing, NICEIC approved electritian in my father in law’s old house. Full gut premiss and full rewire.
I was fixing a gas leak (that I shouldn’t have been doing but he couldn’t get anyone)gas and heating off 3 days now in winter and he’s in his 80s) in the attic for him, put hand down and got a belt off a red and black? I repositioned myself getting another 3 belts off different live cables??
Not insulated and shouldn’t have been there anyway as a full rewire??
He was selling so I did the gentlemany thing, taped it up, 5 in total???
Fixed a leak off a dead leg gas pipe they had caught with a screw but took a while to actually leak, and fckd off.
No I didn’t test as it was going to be a can of worms, told him to contact previous electrician, un available, had accident? Died???
After he chased for a couple of months?
Why is it doing favours for family always ends up a pain in the ass.
I got a friend to check after. I had already done a drop test and would never usually do this for anyone bar my own house.
As far as electrical
What is legality doing your own and immediate family?
Also same for industrial 3ph for my sister’s unit. All tested etc no money exchanged. And nothing dodgy bar not registered with niceic, nappit etc
Has that master plug has got a A type or AC type RCD. Sent a BG version back because it had a AC type.
BG have been a bit slow moving to Type-A as I found in my test rig video when I bought their garage board. This thing does have a Type-A though.
I was sent here from Ruch Oporu....
Not quite such slick production over on this dark and damp corner of TH-cam!
Red shirts always bite the bullet gents. Well done for passing the kobayashi maru Captain David.
Could you use a load sharing device . So that the shower say has priority first
I've used that before Gino including on my own home where the shower and EV charger share the same circuit (shower has priority), but what would we load share the shower with here? The only other circuit we could share it with would perhaps be the cooker, but that wouldn't be a convenient solution and on it's own the 10.8kW unit blew the demand.
@@dsesuk it was a poorly installed system. Bad designer
The chint boards usually use a smaller sized mcb.
Normally supplied with a flexible link from the RCD or Main Switch to the first MCB then the bus bar just connects the MCB’S together. If fitted an rcbo next to the main switch you don’t need the flexible link. Still hard to get the lid on though. Great video as always 👍
It's a shame that it wouldn't have been possible to have Star Trekkin' by The Firm as part of the intro, even if it was audio only
Perfect for a Sunday morning with another bloody cold, thanks for that.
As beefy as that car charger socket looked, are we honestly believing that they have fitted anything other than a standard socket in there?
Get well soon Oli. As for the BG socket, well time will tell. We've put a couple in now, so if we get called back to one that's melted you'll be sure to hear of it here!
There's one way to find out: open one up! My 50 quid's not on the table for that one, though.
how can someone get a Wago wrong?
You need the red top! 🤣 but 10/10 vid!
This video was just like the EIC, Very good.
It's for if the tenant doesn't pay their rent, the owner turns the power off.
You 2s are the master of sorting out electro installations that job is madness installations..,
David I have recently used MEGAMAN down lights that are class II available from DENMANS electrical. Best regards. Kev KMAC Electrical Services.
Thanks Kev. There are many Class 2 integrated examples, but it was GU10 cans I was referring to. I don't like integrated downlights - too hard to put right when they fail!
Great vid. I’ve started to getting a nervous twitch every time I walk into an EICR with loads of down lights.
EIC with only 12 months what a clown.
Thanks for the SpruntJuice Libby. Mine was mixed okay, but Nigel's wasn't. He's trying to poke his nadgers back up as we speak.
You know how to find these gems of craftmanship and when I say gems I mean 🐈 sh1t
Whoever bodged-up these circuits also forgot to calculate and allow for losses in the run of the armoured cable from the barn conversion to the little house, I'm thinking?
No calculations were troubled in the wiring of this installation.
15:46 nige beamed down in a shirt but now has a coat, there’s about much continuity as this site
Great video, keep up the good work guts!
About bleeding time! Had to slum it with Bundy, Fartison and Co. Pull your finger out Savory !!
One thing I don't get is that these breakers won't trip at In. So a 40 amp type b won't start tripping untill about 56A according to figure A4 page 417 brown book appx 3. That shower draws 46.95 Amps. So how is it trippin?
It's not just the shower - and remember that the shower has its own B40 which is not tripping, but the MCB back at the house is also powering the sockets, lights, heaters, cooker and everything else. What perhaps didn't come across in the video, although it was mentioned, was that when we subjected it to stress we'd also switched on other appliances to simulate how the people who live there would be using it. Add in a panel heater, the cooker simmering a pot of water, some lighting etc., and even then the MCB might not trip in short order, but it does heat up and pops off eventually.
I've never known a builder to use a genuine wago. It's normally the spurious Toolstation grey plastic thingies.
Presumably he went in to buy the usual connector blocks and stupid Chocboxes but then spotted these on offer?
@@dsesuk thought he would have picked up a bag of cpc also at the same time.
The LAP fixed LED & Integral low profile ip65 downlights are class 2 bud.
There's klingons on your starboard bow
No, it's just the way my trousers hang.
Spunk Gargler... nnooooooo 😂😂😂😂
If I'd have published this at Christmas as originally intended, Nige might have got in on this year's Oscars.
I'm sure Nigel was sporting a surfer boy haircut towards the end.
Time dilation from all our light speed travel has played havoc with our haircuts.
Wow, I've never seen a lot that's this foul-mouthed but also this professional at the same time. Love it! Are there many electricians like this in the UK?
Most of our competitors hide either their foul language, their professionalism or both.
Yes.
Once again I'm glad I didn't have anything in my mouth at your shout outs. Gagging on a ****. As Nick would say "oh dear oh dear". I had a lot of hot birds on my face this arvo. Cheers
The shower load is constant, temp is regulated through what is essentially a mixer tap. There's no 10kw dimmer in there.
Cracking vid though! Love the technical educational stuff!
Exactly!
Have you made a spaceship out of a snowspeeder and a margerine pot? 😂
Not at all Paul. It was a Snowspeeder and a mackeral tin as revealed in the unlisted companion video: th-cam.com/video/6dww3enhi7s/w-d-xo.html
@@dsesuk wonderful money shots…and I take it this was whilst being harassed by Karen?
Fabulous effort!
