4:27 Hmm... Are you sure that water pipe has a metal incommer...? It looks like black plastic (used before they were blue) to me! Also, isn't it preferential to use a separate bond for both the gas and the water, rather than just daisy-chaining only one main bonding conductor?
It's preferential, but within regs to use an *unbroken* link through from one to the other. Copper is expensive, why run 20m of cable if you don't need to
Gaz, FOR FINAL CIRCUITS (TN) unless the circuit is supplying only fixed equipment where it’s still 32A max for 0.4s, Doesn’t the 18th Regs now indicate a max 0.4s on any circuit containing a socket up to 63A up from 32A?
I never really understood why anything up to 32 amps disconnection time is 0.4, but anything over 32 amps is 5 seconds. I thought it would be the other way round, seemings over 32 amps is more dangerous no? Why am I missing here?
On circuits of less than 32a,especially a socket circuit there's a very good change a person is in direct contact with an item of equipment such as metallic kettle or other appliance so circuit needs to disconnect quicker. Above 32a the circuit is likely a distribution circuit or supplying fixed equipment that a person is not holding at time of a fault.
When I did the 17th Edition of bs7671 exam course it was called "International protection" but when it came to the 18th Edition it was back to Ingress Protection
Well presented again. Love watching your video's having been in the trade 45yr myself. Nicejob.
Massive thanks for that fantastic comment 🦾💕🦾
Bteat video and well explained though it could do with bringing up to date
Thanks a lot. Really helpful, relevant content. Cheers!
Thanks
Nicely explained 👍👍

I would say so as you then have added safety as gas and water is separately bonded and you won't get any false readings as can test cabling separately

Notice you say the protective bonding conductors are connected to gas, water and oil instead of saying its connected to extraneous conductive parts ?
Sound was appalling.
Shame about the mic quality here Gaz otherwise great video
Totally agree and sorry
Really need to sort the audio out.
That water pipe is earth bonded when it shouldn't be?

The video is 8 years old 🤦🏻♂️
@@GSHElectrical LOL. Thought Gaz was ‘looking good’ 😁
You always say it's not an earth it's a cpc , in cabling etc. But you are saying an earth pin on a socket. So what's correct ?
4:49 - I thought that 50V was the limit where it started to arrest your heart, not just become uncomfortable?
Touch voltage is 50v and above and 30ma gradually working backwards has different effects on thr body and heart ♥️

Whats with the curly wurley earth, get a grip
It's incase cable gets snagged allows abit of length
Thought IP stood for Ingress Protection
Internet Protocol 🖥️ Injured person 👮 intellectual property
Same
When I did the 17th Edition of bs7671 exam course it was called "International protection" but when it came to the 18th Edition it was back to Ingress Protection
International protection code
Ip 😂 stands for = I like Pizza😅
why cpc curly? come on!
Incase gets snagged but 😂is abit over top curly
Bad audio
I had real difficulty hearing a lot of it, sounds like the microphone is under water.
Sorry
@@GSHElectrical
Start again.
Plugtop? That is the lid on plug.
Nicely presented video however the audio quality was poor.
Gutted and sorry
