Guys
Is it good practice to zap the old wiring with a 500 volt insulation test before any consumer unit is installed?
Or do you just go ahead and rip out the old one and fit the new?

Hi Guys,
This is the second time I've come across this on an EICR, but with slightly different circumstances.
It has made me ponder if my previous code, and if my current idea for coding is correct or not.
Basically someone has bodged an extra single phase supply off the incomer side of a 3...

Hi Guys and Gals, currently I am finishing off my NVQ & i'm being asked the question on One file "Check the safety of electrical systems prior to the commencement of inspection, testing and commissioning".... Is this just fancy wording to say check Ze before you do anything else?

I'm now waiting for double socket with integrated toilet roll holder.

A question for testers to settle a debate at work - GN3 & regulation 612.3.1 state that when doing insulation resistance, the CPC/armour of swa MUST be connected to Earth.

Morening all,
I have a dilema that you may be able to help with.
Manufacturers instructions ask for the unit to be fed from a C Type 16Amp MCB. At the moment this is all the technical information I have.
In one in twenty cases they experience nuisance tripping and have now recommended fitting...
Hi guys got my assesment in 3 weeks and want to get my testing spot on. Little confused whether to test Zdb on 2 way CU before dead tests?? Or do I jump straight into continuity? Thanks in advance.
I was asked by a friend to connect up some lights in their store room. You can make out the cable on the ceiling coming out of the conduit ready to be connected to one of the CU's.
This is what I came across.
I said 'No'! :)
Hi,
If you're a spark, you're reading this, your name is Kevin, you work in the Manchester area and you did a job in Rusholme yesterday on lights that kept tripping the RCD - Please reconsider your career before you do serious damage.
It's forgivable that you were unable to diagnose an...
I have been reading posts on this forum for quite a time, and some people have been criticising Part P as though it was a wonderful world before Part P came along.

Been doing a CU change today. House was rewired in 1999
Picture of inside of Wylex board:
This was one of several marks that the cables had left - and yes its heat damage to the enclosure..
The cables aren't damaged, and as all the rings were protected by 16A MCB's its not exactly a high...
Got a job where im having to do the usual testing.
I have never tested a set up where due to the tails needing to being so long to reach the consumer unit there has been a switched fuse, this is i believe a standard directive from the DNO the tails then terminate into swa and run from the...
