Voltage difference

[JohnW2]

Easy to check, measure L - N and L - E at both sockets.

That's 'almost' what the OP had done, after I asked him to measure L-E at the 'non-working' ("208V") socket....

We know that the non-working socket has 208V L-N and 241V L-E. We also know that the working socket has 240V L-N, and I would be very surprised if L-E at that one is not similar (i.e. around 240-241V).

Kind Regards, John

You're right John. L-E at the working socket is 240v.

You're right John. L-E at the working socket is 240v.

Thanks. That obviously re-inforces my suggestion.

In passing, I forgot to mention ... what SimonH2 said a while back seems to be true - i.e. that what you said in your initial post seems to suggest that what you have done is probably non-compliant with regulations, if that concerns you (if I, and Simon, are understanding correctly, there is a theoretical danger, but probably not an 'appreciable' one).

Kind Regards, John

Thanks for your help John. I will get an electrician in to sort this out.

Regards.

John.
