rewiring

[AJAY198887]

Hi, I have just bought a ground floor massinette, and asked my electrician for an electrician certificate. He went into the property and opened a few sockets to have a look at the wiring behind. The wiring looks in extremely good condition but is only black and red separate single wires (not 2 wires in an outer casing). There is no earth wire. The sockets have a wooden box behind them instead of the more modern metal ones. My electrician has stated that I have to have the full rewiring redone in the whole flat. I just wanted to check if there was any way around having to get the full rewiring done as the massionette is fully decorated to a high spec.
Thanks in advance.

More likely a" Socket and See Tester" could be a DIY Dave electrician.

And was is wrong with Dave.?

is there any test date on the 17 th board .

Yep "the reading was a bit low"

Which Dave are you talking about?

could even be conduit with the condiut used as cpc. further investigation by a competent electrician id needed before you go ripping the flat apart to rewire.

Get another opinion from another electrician.

Like others, I haven't seen an installation where the socket patrices are wooden - only light switches.

Used to use these on wooden switch boxes, believe you can't use them anymore.

IMO, he could be correct, wooden back boxes is a no no, in the sense if it needed rewiring they would need to be changed, is it red black pvc or VIR.? More info is needed regarding his test, could be low IR.

Yes sir the red and black wire are pvc and very good condition

How do you know that they're in good condition? Looking at them inside the dB or at a socket or switch tells you nothing I'm afraid. To know they are in good condition you need to put 500v through them and see what the meter tells you.

Also, you would need to know if there is a CPC serving the length of the ring final circuit, which as there's no earth conductor and wooden boxes I would highly doubt it. Again though, this needs to be ascertained through the correct test procedures.

It's in steel conduit, therefore there must be a cpc at every point already

Has anyone ever seen wooden back boxes??? I have seen plinths/pattress but never sunken box. I suspect this is metal conduit with singles drawn through. If so I may be possible to draw an earth through and change the boxes. A picture would soon scotch that conjecture.

Steel conduit is a cpc so why would you add another one inside it?

picture would be nice.
