Ok, bad turn of phrase, I wasn't saying this would start a fire. The point I was trying to make is that if you do a calculation according to the BYB stick to what it says, dintbthen second guess it. That is your safety net. If you stay with that, then nothing should go wrong and if it does, you can always say, I followed BS 7671 to the letter and you are fully covered.What fire are you predicting here? 6mm SWA has a ccc of 49A single phase clipped direct at an ambient temperature of 30c which is well above the nominal current of the circuit.
