Advice on regs please

[Shock Doctor]

Hi all,

Ive just come back from looking at a job. Customer has 3 electric heaters in thier flat only one is working. Had a look and the one that works seems to be wired into the ring main. The 3 15a radials wired in for the heaters have no power getting to them. The board is a split feed with no RCDs one side works fine but the side that has the 3 heaters on has no power. If I disconnect everthing and straighten out the feeds so I get power am I required to RCD them as well? There is a 40a add on to the side of the CU for the shower which has no rcd either. If I get involved in this am I going to be responsible for everything else?

All advice as usual gratefully received!

When you say "one feed is split" are you talking about the Line or Nuetral conductor? it's difficult to pass comment without at least a couple of pics and more info. What is the current rating of the heater being fed from the ring main and how is it fed i.e from the board or a spur?

IF it's hard wired & not in a special location surelly it dont need rcd protection. are cooker's rcd protected.

Err, yes, if installing to 17th ed, everything is rcd protected unles you meet certain rules,

however if none of the circuits are being modified and you are just fault finding and replacing faulty equipment then as far as i know you will not have to add rcd protection.

I would start by downloading the part p document from here Approved Document P: Electrical Safety - Dwellings (2006 edition) - Planning, building and the environment - Department for Communities and Local Government

A book worth buying is the electricians guide to the building regulations.
