Help needed from Expert Electrician!

JaiS

Hello there,

What began as a simple kitchen refurb has turned into a bit of an electrical nightmare as we have discovered 30 year old wiring in the house alongside new wiring. I am sure there is a solution here but we have tried everything.

Here is the problem, if anyone can help or point me in the right direction that would be much appreciated as the electrics probably need condeming at this point.

This is for a property in Nottingham.

We have just upgraded the consumer unit from a very old wylex unit wıth the old fuse wire as the lights went off randomly and was advised by many electricians to upgrade unit so it meets new regs.

We have noticed there's no PME at all from main feed into the house and have wired all up to correct fuses but still no lights.

We checked all the terminal boxes under the floorboards and all the wıres are still connected.

Also the cooker every time we try and switch the oven or hob on it also trips the whole consumer unit out!

An electrician has been in and cannot fıgure out what the problem is!

Also wen tryIng to rewıre a new lighting circuit we came into a lot of old 1977 wiring running throughout the house but to nothing. Yet still connected to the current ones so we cannot fıgure out where there comıng from.

The electrician has spent nearly 4 hours with a electro reader and cannot locate as they go to the ring main and he saıd this dangerous as it means we have a free flow live.

Any ideas or questions or suggestions would be extremely helpful as we are a bit lost!

Thank you!

If you are rural, it may be a TT system. Check with the power utility company for your area.

The person who installed the new consumer unit should have carried out a full EICR prior to changing it.

The problems you are having would most-likely have been identified before changing the consumer unit over.

The DNO will only supply PME (to make it into a TCNS installation) if the supply system and the system to which it connects are up to it. If the supply system is no-compliant with a PME solution then you won't get it. Your electrician should know this. Get another sparky to examine your installation and give you an opinion.

Thanks Myser,

A full EICR was done and we are not rural but in Nottingham center, that's why so many people are totally confused!

Have you contacted your local power utility company?

You mean the DNO of course not OPs electricity supplier (the company he pays his bill to)?

Cheers

Myser

Yeah I do mean the Distribution Network Operator. I didn't want to confuse the OP with more acronymns!

Yes good point although I half expected that if he knew PME then he would know DNO. For those that can't be bothered to look it up it's Distribution Network Operator.
