I am working my way round the house room by room, and have just started on
the sun lounge.
I have an arrangement of two sockets side by side in a fancy double wall
One socket is a single 13 amp 3 pin, the other is a single round pin 3 pin
(like the old 5 amp IIRC).
The wiring is grey sheathed T&E 1mm or 1.5mm AFAICS and wired as a ring
i.e. two cables both wired into the socket.
The extension was built in the sixties or seventies (we think) and this
wiring will have been done then. The wiring in the rest of the house does
not use this scheme.
As far as I can tell this is not current(no pun intended)ly in use but
when I put my cheapo digital multimeter on the A/C setting it shows U/L
(overload) very briefly then settles down to showing about 9V between the
live pin and the neutral pin or the earth pin; earth and neutral are at
the same level. I assume that this is acceptable.
I am assuming that there is no connection to anything live, and wondering
what this may have been used for in the past.
I was considering replacing the wall box to allow me to fit a twin socket,
but looking at this the easiest thing to do would be to add another single
socket to replace the round pin socket. Probably as a spur depending on
the amount of free cable. Is there any benefit in doing this over using a
distribution board/extension lead?
Bit of a rambling post, but there you go.
