Sounds like a problem waiting to happen. I'd get an electrician in to do this for you properly.
Yes it does on a 32 or 30Amp Radial circuitThis is somewhat unconventional and is clearly ad hoc, yes it should be on its own circuit as I have also suggested but the limitations of what can be added to this spur is clouded by the cable size, 4.0. Appendix 15 which is informative does not demonstrate the use of 4.0 cables/conductors.
if the CU is in the garage anyway, why not split the tails with \Henley blocks and fit a "garage board". RCD + 2/3 MCBs. then a fault in the garage will not saffect the house CU andyou would have a spare way/s. a 4mm 32A radial for sockets, 6A MCB for lights.....
I am talking ring final circuits. But yes you could consider this a 4.0 radial so I see no need for a fcu but circuit separation should be employed.Yes it does on a 32 or 30Amp Radial circuit
Wired in 4mm2
2oAmp Radial wired in 2.5mm2
I was referring to the option of fitting an additional CU for the garage etc that was mentioned earlier in the thread..Adding/altering this existing circuit would not be notifiable.
The spur would normally be in 2.5mm2, but the fact that it's in 4mm2 is not a problem. (Might be a big garage, VD and all that)
It's a spur from a 2.5mm2 RFC albeit from the CU, no problem with that, why 4.0mm2 was used is a mystery, it makes no difference to what you can and can't add, a spur is a spur, one twin or single socket only fed directly from the RFC without a FCU involved. Nothing to do with the B32 Amp CB rules is rules is rules.Is this because it's on a B32 MCB?
Where is this rule for a 4.0 spur.
Not one as far as I am aware, Westy. I was just wondering why a 4.omm2 was used, just makes life dificult for the installer.Where is this rule for a 4.0 spur.
