I am about to rewire my consumer unit (the current one is very old and
doesn't
support RCD). To diy it, I think I need cut off the mains supply first.
However,
I can't find any switch around the incoming mains. Should I contact my
power
supplier to temporarily cut off the power during the installation? Any
suggestions and comments are very much appreicated.
Best wishes,
Bing
Cut the seal off the mains fuse and pull it out. Simple really. If
you're
going to be pulling everything off the wall and installing all the gear in
new
positions, then it might be best to pull the neutral supply out of the
head as
well to be sure of not touching that to earth and causing sparks or
tingles
through you body.
Once you're all done with the installation, then contact your supply
company and
have them come do their tests, checks, prods about as they do, and re-seal
the
head end for you.
Don't worry about cutting the seals off the mains head end cover and the
terminal cover of the meter, it is not against the law to do this, it's
only the
seals of meter that are protecting the adjustment gear inside that really
worry
the electricity suppliers.
So. Don't touch any other seals on the meter other than the ones holding
the
cover over the connection terminals.
And REMEMBER, once the fuse is taken out of the main head end supply. The
exposed parts inside are at high mains voltage. So make sure you don't
touch
them with anything.

While on about, meter adjustments, would disconnecting the main supply fuse
interfere with the settings on the newer electronic digital meters? Do they
have a non volatile memory and if so, how long have I got!?
