[QUOTE="AttitudeAllStar, post: 555250, member: 37890"] Thanks Andy - I am presuming it is down to the draw on the cable... if a 2.5mmsq cable is drawing 31.9 amps and the breaker doesn't trip, then the cable is at risk of melting isn't it? It's not designed to take 31.9? Maybe a ring main works differently. I'm not an electrician :confused: Very clever Binky! That is absolutely the solution. The cable that is on it is a flexible 2.5mm I think, pretty strong, maybe it is 4mm, there are no markings on it, I think it's best to just replace it with 6mm and wire it exactly as it states using the 2.5mm diagram. I'll need the oven and hob to share the load, so maybe using a dual connection plate - would I be correct in saying it is more or less the same as a surface mounted junction box with three 45A-60A terminal strips.
