Evening all.
A customer has asked for a dedicated radial circuit to feed 4 2g sockets.
He has asked for the cable to be rated at 45amps as he said at times the hifi equipment may reach this current. He is very specific that he wants the cable rated at this as a minimum.
He has asked for the 6mm to be terminated into an enclosure by the hifi which then feeds out in 2.5mm 'individually' to each of the sockets which are right by the enclosure (like an old spider circuit for lighting).
My plan was to use a 45A MCB for the circuit as the 2.5mm cable supplying the sockets will not need overload (O/L) protection and fault protection will be offered by the 30mA RCD (TT). Reference method will be 'C'.
I'd be interested in any opinions on this as it is a different style of circuit to 'normal' and those shown in appendix 15, but as stated fault protection is in place, O/L protection in place for the 6mm cable and protection against O/L can be omitted for the 2.5mm cable feeding the sockets (433.3.1 (ii)).
Cheers.
