I have deleted my earlier comments as being a grumpy old spark who’s opinion means nothing. I feel I may off offended some people witch mean’s my research was pointless. Never mind the fact I was right. Fantastic video as always Gaz 👍👍👍❤️
In an instal that old would the incomers be live because I couldn't tell if there was an isolator. Or did the main fuse fall out of its own accord when you weren't looking.
New On-Site Guide (Amendment 2) now states that "where the insulation resistance measured is less than 20MΩ the possibility of a latent defect exists". This was in the previous GN3 but not the On-Site Guide.
@@MizunoIronMan it also say the an IR test at 250 v DC shall be carried out between line conductors and the protective conductor be for equipment is installed? This is to avoid damage to sensitive electronic equipment. This implies that we test line and neutral combined to earth earth, this is a test we have always done at 500vDC And as there is no pertenchal difference it’s highly unlikely that such a would damage any electronic equipment.
@@seandempsey7351 I know what the correct values are thanks. I was just highlighting the fact that there was a frustrating inconsistency between the OSG and GN3 before the new Amendment 2. Maybe it’s the punctuation that threw you a bit .
Why did he have to change the CU? Don’t anyone bother with the onsite guide ie page 99 consumer units in dwellings , and the health and safety executive’s note page 4 of BS7671 . With out an explanation as to why he has to change the CU tells me it is another CU change for no real reason. Other than adding the cost of the new one to the bill.
Unfortunately having many circuits on a rewireable fuse causes issues when a fuse blows. Separating circuits on to separate RCBOs means that any fault on one circuit will have less of an impact for the customer. Also flipping a switch is a lot quicker than having to replace the blown fuse wire.

Love these "on site" videos as opposed to the staged videos. Brilliant. 👍
Are you guys going to do a follow up video to show where the fault was?
Betting it will be the external lighting/joint box.
It was the outside light 👍🏻
I am a training channel so the classroom videos will always be my go to however I do have about 10 on-site videos ready for release 👍🏻
Thank you ❤❤❤❤❤
Yet another great “tutorial” simplistic and precise, I would take the knot out of the test lead tho, just to be pedantic 👍
🤦🏻♂️
It's a current limiting knot 🤭
Been too long since I've heard.... I hope this video has been some help, great work chaps
Thanks Andrew for returning 👍🏻
Very helpful informations
Thanks 👍🏻
I really enjoyed this
Thanks
Great video guys
Massive thanks 👍🏻

Excellent video with Gaz in his best role as questioning tutor. Marcus is clearly first rate: presumably a former student?

It’s said that for along time 👍🏻

Do you have to disconnect the loads when you are only testing between the live conductors and cps?
Have you got a video on the 014 assessment would be great to see one on that
I'm hoping to do my 2391 this year

Did you take the lamp out the outside light before testing?
It didn’t have one 👍🏻. All loads removed
👍
The board looks so simple compared to the elaborate offerings nowadays K.I.S.S 😅

@@seandempsey7351 Look up the reasons you require "additional protection" in a dwelling and there's your answer/s for a consumer unit change. 👌

@@seandempsey7351 I think the understanding is they were checking before doing a CU change.
