I'm buying stuff to run a 4mm2 radial... what depth back box do people suggest? 35mm?
I normally use 25mm ones for ring mains but I'm wondering if I might struggle to get two 4mm2 T+E and a 2.5mm2 T+E in the box behind a DP switch.
(No need to reopen the FCU/DP switch or is a DP switch rated to 32A arguments!)
Thanks
