On a domestic inspection and testing certificate or conditional reports, I always put maximum disconnection time permitted by BS7671 as 0.4 sec. I've been given a testing job for an HMO property and on the previous conditional report, the maximum disconnection time of 0.4 sec is only given for...

hello.
Dejavu for some folk, but here’s the scenario:
My house is two-storey brick, my shed is 10’x3’ (odd size I know, but the back yard is small) made entirely of wood, no metal at all.
The gap between the house wall and shed is 300-400mm.
At present there is no power to the shed, so I have...

There was a post yesterday, can't recall the exact one. I'll start by saying I wouldn't do it and never have, there were several reasons and answers that, although they provided some sort of response, there was never any definitive proof as to whether it was against the BS 7671.
Now I don't know...
We are rewiring a stair lighting circuit and the door entry supply passes through one of our light fittings which is a seperate circuit from the lights.
Is this ok if it is marked up at the DB?
Hello,
I drilled a hole late last night after a long day and stupidly didn't check the wall directly under the plug socket (I know).
The RCD tripped and it appears to have just exposed the copper wires, just the sheath is damaged (pics attached).
From a bit of googling it seems there is no...

Hi,
I have asked an electrician to install electrics in my house's garage. I'm happy with the electrical work he has proposed and quoted for, but I wanted to check his approach to running the cable to the garage.

Hi gents,
I am going to a job to install some new external lighting on a factory on Monday. There are 5 new circuits to run in total. They want these to be controlled by a time clock an photo cell but also run through a key switch and contactor. It’s been some time since I wired contactors and...

Hi all. I know there is a DIY forum but im really after your expert knowledge rather than fellow DIY'ers/amateurs.

Hi All
I have a domestic two storey house to wire with hollow concrete slabs on the first floor and I was considering drilling all the sockets etc down through the slabs to save the wall tracking. Does anyone know if this is permitted with building regs?
Thanks
Hi
I don't know if anyone can help, but I'm very grateful to anyone who can provide input. I won't go into the full story, but my windows upstairs appear to have an electrical current running through them.
It's only the windows upstairs.
They also set off a radio frequency detector.
Even if...
Hi, I am laying a patio and have a 38mm corrugated conduit going across the ground ready to be covered in scalpings, it's 7-8m long but it doesn't have a pull cord though so I was wondering what's the best way to get cable through it. The cable will only power a small foundation pump. Thanks
Just saw this. Great demonstration of how NOT to install insulation round electrical cables. No consideration of the CCC of the cable.
Sorry pete, I know this is your job, really.....:D
