Ring Circuits - Fixed Electric Heating

Former Community Member
Former Community Member

Dear All,

I have been asked to review a proposal for an apartment where it is intended to use a ring circuit (4.0mm T&E) to supply 4 No. fixed electric panel heaters in the living room @ 1.5kW each (6kW).

Does this meet the BS7671. Regs/On-site guide refer to ring circuits and 13A sockets.

Any guidance would be appreciated.

Thanks

  • Why use a RFC?

    what about the revolutionary idea of supplying 4 times 2.5mm² radial cables protected by 4 times B10A MCBs?

    Add in a socket circuit and there’s around threes times the amount of cable actually required.

    CEF prices not discounted

    2.5mm² = £80.00

    4.0mm² = £180.00

    So I'd expect the ring verses radial would cost about the same without the same discrimination.

    We do not know why the OP wanted a ring, or indeed 4mm - it may be distances and voltage drop, it may be grouping factors, it may be a misplaced desire to do what feels like a belt and braces job.

    The question was not 'are there alternative layouts that might be better?'

    That answer to that one is 'probably yes',

    The question was  just 'is this OK?'

    also 'probably yes'...
