Voltage Fluctuating

[m4tty]

Hi,

Was checking some electrics round a house on Friday and came across loads of problems. Possibly the worst I've seen. I'll post up some pictures later on when at home on computer. I found junction boxes fixed outside on pebbledashed walls with single socket cemented into the outside of an extension with bare t&e showing. It really was bad.

I found majority of sockets in house ran off a 6a lighting circuit all with earths cut off ffs.

The reason for this post was I was checking voltage at sockets and on 2 o the sockets my mft1552 wouldnt read a stabilized voltage. I've videod the display on my tester for 30 seconds and it fluctuates from 238 to 260 v. It flashes constantly jumping from 238 to 240 then 242 which goes up to 260v then back down and up. It wont stay still. It does on most sockets.

Also the kitchen light has been wired from a 32a circuit not fused down.

I'm going back beginning of September to sort out so will post more pictures then. These include melted cables outside which are

Still being used ffs.

I'll post pics later on but why would the voltage be up and down at specific sockets and not at the board ?

Cheers

Sounds like an urgent rewire is required

TBH if you've got a fluctuating voltage at only a couple of sockets then you've got a loose termination somewhere

+1. Hope you`ve covered yourself by giving `em Elecsa`s version of an "XNN" Danger notice?

I'd go with Noz and KME , urgent rewire, issue danger notice , ( do ELECSA do them ? I don't have much to do with them TBH)

You can't overload a 6A socket circuit but the lack of earth is worrying .

The melted cables outside are worrying too , what happens when it rains?

They cool down then.

Heres a few pictures of it

Bottom pic the waste water from the washer?

Don't want on blockage coming back up it.

Matty that lots going to keep you busy if you do the job.

Matty is that socket and JB outside ?

If I'm understanding the pictures, that's not actually "outside" but inside a (possibly rather poor) lean to / conservatory.

But I do agree the workmanship is poor, and the faults all need dealing with urgently. I once found a washing machine and tumble dryer connected to a socket on the lighting circuit, and someone had changed the lighting fuse to 15A because the 6A one kept on blowing ffs.

Agree danger notice would be appropriate. If a gas fitter encountered such serious faults, the customer would find themselves with no gas until it was put right.
