[QUOTE="phil d, post: 443267, member: 27126"] A while ago I posted the values the dno uses to work out its loadings on it's circuits, off the top of my head for a house with gas central heating it's something like 3 or 4 Kw per house. Thats what they use to calculate their loads for feeding say a housing estate, it obviously works because if it didn't you'd get substation fuses blowing all the time, as someone else said, it's surprising how little current a house actually pulls. I was looking for a fault once and I had everything on, electric shower, electric cooker, water heater and loads of stuff on the sockets and I was still pushed to pull over about 40 Amps, Diversity plays a big part in calculations and loading, plus a fuse doesn't blow instantly and it takes a while to blow.
