Hi All
I want to tidy up the garage wiring and add a few more bits, Im thinking that a second CU would be the easiest with separate sockets\isolators for individual equipment (compressor, pillar drill, lathe etc) Im looking at 16a radial for the compressor (3hp motor) with 16a 230v Blue, round 3 pole plug\socket and standard 30a ring main for the rest (all 1/2 or 1/3 hp motors) or hand tools plus lights on 6a radial.
Should the seconday CU be fed from an MCB off the primary CU or direct from the isolator, or the incommer?
and what size cable to use to link both CUs -we're talking appox 15m.
(its all certifiable (arent we all!) I'm just doing the labour and prep work to trim the bills down)
