Finding the combined insulation resistance can be achieved by your long-winded calculation method - or - you could just test with all the circuits connected. Maybe that would be too easy.
You can perform a global test... but what does it tell you? It doesn't tell you which circuit(s) are upsetting the RCD, only that the global IR is shite - which we already know if the thing is tripping off. By taking the baseline numbers, if the fault reoccurs we can re-test and see what has changed, then we know which circuit to start looking on.
@@devonfuse Ah, I see - you're talking about undertaking a global test after checking the individual circuits and instead of punching keys on a calculator. Yes, you can do that. A physical test should match up with the maths.
You might talk some crap but you know your stuff, explain it well, entertain and teach me some things I didn’t know. A happy new year to ya David. 👍🍺🍺🍺
There is nobody else on TH-cam who can make getting pissed into a work of genius. A belated merry Christmas to you, and here's wishing you a happy New Year. 🎇
Mr Savery, as a card-carrying CofE member, I do find your comments about being a heathen rather comical. I follow your channel because you are, without doubt, one of the nicest and most honest Electricians I know. If only more "Christians" were as dedicated to safety and other people's welfare as you are, the world would be a better place. That won't go un-noticed by the Big Man upstairs! Happy New Year to you and yours!
I did lots of churches years ago. All in pyro, the attics were untouched for 100+ years, every wall was at least 1 metre of drilling and this was before SDS came in.
Thanks for the mention. Great Edge, among other things, normally tries to contribute puns for your video titles (DSES 62606 et al), but was logged into the wrong account when clicking on ‘buy me a coffee’ ;). Handy to know about the 118mm LED - saves me a luminaire replacement on a current job.
BRAD MY MAN! My apologies, in my haste to record the coffee shout, I neglected to perform a basic look-up where I would have spotted your name! Happy New Year and keep the wordplay coming!
15:05 nicely lit and good colour scheme for you David. Almost looks studio lit. And thank you for signing off with '25' I waited 25 Years to hear that since 99.
Great video David👍 Just to add further to your point about the reciprocal of resistance for any one reading the comments. This is known as conductance i.e. the ease of which electric current passes. it has the SI unit of Siemens (S). Some multimeters, like a fluke 87V, can actually measure conductance (might just be an internal calculation, not 100% sure) which gives a readout in nano Siemens.
What colour temp was that thing? 3000k would have been better IMO. Unless it's the camera making it look like nasty 5-6000k. I went to the midnight mass this year in one of the big Liverpool cathedrals and they are still using SON inside, and to be honest... that golden yellow glow looked flipping ace in a building like that! Have a great new year chap!
It's true, pubs and churches are an absolute electrical nightmare from past experiences. So what was the first ever trade? Electricians because when God said let there be light we'd already been in and first and second fixed 😊
Churches are always going to be poor at temperature control, because of large high roofs, spires that dump heat out, and them not really having the money to properly insulate them.
Light bulb, fuse box, plugs etc are all things that customers or non skilled know and relate to, you go into someone’s house and ask where your distribution board is or what luminaire has gone wrong they will look at you with a weird look !
Totally agree. I find my self calling it a consumer-unit-fuse-board more often than not. I also hate ‘lamp’, a customer knows a lamp as the thing sat on the table, not the glass blob screwed into it, so I’ll call it a bulb quite happily!
To be honest, the job tracking software I use is very old - if I were starting again then I'd use the functionality built into the quoting/invoicing software I pay for (YourTradeBase) - there's an affiliate link to that in the description if you want to give a free trial. I think it's important to have some kind of job tracking solution though. If you have the regimen to keep the logs updated then you'll know where you've been, what you've done, what materials were used etc. It comes in handy to have that audit trail.
What are you talking about lightbulbs I didn't see any oil lamps? A oil lamp or gas lamp in the US would've been retrofitted to be an electric lamp so lightbulb would be a natural thing to say.
Ps can confirm churches are ice boxes. Was doing an eicr on one on the weeks before Christmas and it was definitely warmer each time i went out to my van.
There's much trial and error on sizing and shaping I find, although brick colour turns out to be surprisingly unimportant even if it does end up looking like Marge Simpson or Peppa Pig.
I would have done an led flood. If its not on that much and its inside so its no so suceptibal to moisture etc. Or you could jave sold rhem an par 56 led fresnel and a basic dmx controller or keot the switch if they only need on and off.
We had to slot this one in as a last-minute affair on our (already busy) last working day before Xmas, so changing the lamp was about as much time as we could give it.
You said that replacing the mcbs with rcbo's that an IR fault would only take out that particular rcbo, but that would only be true if DP rcbos were used as a N to Earth fault would still be present with SP rcbo's. I know I'm a twat :)

@@dsesuk indeed so, but having tested the individual circuits, this one more test is done in seconds.

All the best for '25 - bottoms up!
These places always feel colder inside than outside! Need a few 500 watt halogens to keep the chill off!

@ no problem - not often in life that one gets reclassified as a virgin due to technicality ;)
You can still get 300w linear halogen, used as heat lamps in fish and chip shops (other types of restaurant may exist)
15:05 nicely lit and good colour scheme for you David. Almost looks studio lit. And thank you for signing off with '25' I waited 25 Years to hear that since 99.
Just my USB projector light and some side lamps old sport. No thought went into it!
Happy New Year David.
Right back atcha!
I fitted one of them wider led replacements. 30W 3000k. Heat sink on the back. Fan inside. An excellent replacement for a 500w. Twas 2 years ago.
Great video David👍

That's interesting - and there's a spunk gag in there somewhere too...
@dsesuk 🤣🤣
Happy new year Dave, all the best in 2025! May your next victim/apprentice have equally thick skin and good sense of humour!
All the best for '25 old sport.
Happy new year David, looking forward to more childish content with a bit of electrickery thrown in.

When the call comes in on the last working day before Xmas, they'll get whatever's in stock on the van! All the best for '25!
@ Indeed! 😂
A happy new year to you kind Sir!
And to you Jim. May you get plenty of cocks in '25!
@dsesuk hehehehe. Love a cockatoo.
BuLbS gRoW iN tHe GrOuNd DaVe 😅 Hope you had a great and pissed Christmas .
Mate, I've been perma-drunk for over a week now! It's great!
Lamps are for lighting, bulbs are for planting 😂

Why do electricians have to use different names for common items from the names that the other 99% of the population use?
That would be more of an Eccumenical Matter
That's what they all say when the law catches 'em with a Terabyte of child porn.

Great content as always. What software do you use to keep office admin ? Wish I was as organised as you. Happy new year David 👍

Thank you for a whole year of entertainment may 2025 be just as good
Was it a whole year? I must have missed some vids 😂
There’s better replacements for them flood lights that aren’t a roll of paper inside a tube but more of a molded glass bulb with a cob filament.
Still trying to ping that ming
How dare you make me learn some things surrepticiously (does the lego provide an adequate “feel”. Asking for a friend).
There's much trial and error on sizing and shaping I find, although brick colour turns out to be surprisingly unimportant even if it does end up looking like Marge Simpson or Peppa Pig.
Peter Bryant must have been comparing you to Artisan 🤣 Happy New Year Dave
Comparing or confusing ?
comparing... we know hands down Dave's a better spark
I would have done an led flood. If its not on that much and its inside so its no so suceptibal to moisture etc. Or you could jave sold rhem an par 56 led fresnel and a basic dmx controller or keot the switch if they only need on and off.

Say are them "FLIPPERS" on your feet - to a scuber diver - that makes them boil !!!
20th December, how cold do I expect it to be? Hmmm, I think it was round 29c on the 20th. Brrr.
It could be a heatwave outside, churches are still fecking freezing
@@dsesuk It only stands to reason, if hell is a pit of flames, and heaven is the opposite, it must reasonably be freezing cold.
You said that replacing the mcbs with rcbo's that an IR fault would only take out that particular rcbo, but that would only be true if DP rcbos were used as a N to Earth fault would still be present with SP rcbo's.
I know I'm a twat :)
Do you mean as far as the upfront RCD is concerned? Because we'd have whipped that out for an ordinary main switch.
@@dsesuk No ... if you have an all rcbo board utilising single pole rcbos instead of double pole ones, they will not clear a Neutral to earth fault.
Two electricians to change a light bulb?????? No wonder bills are so high
How is Nigel?
Overpaid and underworked according to his communication on Christmas Eve.
@@dsesukhe found the holy grail 👍
