[QUOTE="Zeespark, post: 233775, member: 400"] Right to Tom and Slipshod, I apologise. I have just redone My numbers by the OSG (Red) Table 1B page 97: 10A + 30% full load + 5A if a socket outlet is built into the cooker switch. 12000/230 = 52A 10A + (30% of 52A) = 25.6 + 5A = 31.6 A A 32 Amp MCB would suffice for the job Tom. Its been a while (2 years +) since doing a cable calculation, so I apologise of I have screwed the pooch so to speak. AndyGuinness [/QUOTE]
