Hi guys,
May be doing a partial rewire of a house including a new consumers
unit with slip load RCD protection and the main task of rewiring the
lighting and adding main equipotential bonding conductors ans
supplimentary in the bathroom.
The old lighting circuits both share one MCB of the old MEM push-pop
type and are wired in twin core rubber cable. Intresting feature is
the plateswitches have no backboxes so they really do need this work
doing.
Any advice on how to rewire this lot in a furnished ocupied house
without causing a lot of disruption and damage to decoration.

The exisitng installation has has got a 6 way MEM board with type 1
MCBs and a 2 way Wylex board with a 30a BS3036 for the shower which is
not permitted. Im planning to replace both with a Screwfix special
Volex consumers unit. I shall be removing the boards fuse to isolate
the supply as ive doen it before and have an ERG39 cirtificate anyway.
But the meter is right ontop of the cutout only separate by what looks
to be an enclosure with seals and the new white digital meter ontop.
Ive never had to acces the terminals on these before any tips ? As i
will be replacing the tailings with 25mm2 and a 16mm2 main earth both
tails will firstly run into a DP switch in an enclosure.

Cheers,

Jon.
