Hello all,
I've recently moved into a house which has an old style 6 way fusebox, circuits arranged thus:
40A Cooker.
6A CH pump/boiler/controls
30A Sockets (study, hall, beds 1 & 2)
30A Sockets (lounge/diner, kitchen, utility, beds 3 & 4) Single socket in garage is also spurred off this ring.
6A lights (upstairs)
6A lights (downstairs, bathroom & garage).
There's also a seperate single 45A fuse/switch unit for the shower.
We're doing the kitchen soon so I'm replacing the fusebox with a split load CU. I'm keeping most of the circuits as they are except I'll be putting the kitchen/utility on its own ring and running a separate feed for the garage.
Additionally, the shower (10kW) is on 6mm cable, so I'll be replacing that with 10mm.
Also the meter tails are currently 16mm so I'll be wanting to replace these with 25mm!
My questions are:
1) Who is responsible for the cabling from the master fuse to the meter and from the meter to the CU/fusebox? Is it the distribution company or me? I tried phoning them but was told by the robot to 'call back later', so I did, and was told to 'call back later' so I used the online enquiry. They'll get back to me within 10 working days............
2) Will the shower need a seperate RCD or can I just take it to a 50A MCB on the RCD protected side of the board (80A, 30mA RCD)?
3) I'm going to need at least 6 double sockets in the garage, I will probably be using some fairly heavy equipment in there (MIG welder, pillar drill, lathe - although not at the same time!!) as well as having the usual bits and bobs plugged in (freezer, phone, radio etc). My thoughts are to have a separate CU for the garage, fed by 6mm T+E cable direct from the CU (effectively using the CU as a junction box) and have a RCD and a 32A MCB ring for the sockets and a 6A MCB for the lights (6x36W flouro). Would this be OK or is there a better(correct!) way of doing it?
Also, should the sink/pipework in the garage be earthed back to the (garage) CU?
4) What size cable should I be using from the CU to the earth point? AT present it's 6mm.
Advice much appreciated.
(I will be notifying BC about this BTW )
