I have a 13 amp. fused connection unit. This is fed from a socket which is on a radial circuit.(load on this is 100 watt)
I want to take a spur from this to feed another fcu which will feed an outside light. (load will be 300 watt)
I know that regs. do not allow me to take a spur from a spur , but as the total current is controlled by the first fcu, is this ok.
