[QUOTE="ProDave, post: 503169, member: 6969"] I have never "understood" 4mm cable. I don't personally use it. Why would you? In theory it;s good for 32A under certain circumstances. Okay. Simple question. Would ANYONE here use 4mm for a 7kW electric shower? No I didn't think so. So if not, why would you use 4mm for anything else fed from a 32A mcb? [/QUOTE]
