Hi all,
I have a shed wired for 3 phase. All the red 440v sockets are working, however in recent days the standard 3 prong & blue 240V sockets have stopped working. I have a decent knowledge of electrics that I have learned myself. The 240V comes out of the breaker board from a single wire to all plugs, there is one single blue breaker that seems to not have the same spring in it when pushing it. It reads MCG SP632C. I'm not going to repair myself but can anyone indicate what could be wrong? The plugs and wire going to the board seem fine.
