[daveb1]

It is interesting seems like it is the right way of calculating it after all then.

200A 1 phase services very common in oz now,but at a guess a 500kva tranny would be ok,diversity plus reputable English and yank stuff can handle 300 percent overloads for 10 hours at a time with no effects.200A service due to the 80 percent rule means 160 plus POCO here will usually still only install a 100A service drop,they have their own rules,free air that sort of thing

Well I think 0.4 for everything seems right .. From what I see. I normally use highest breaker + 40% of rest and it's too high ,but I write it in if under a 100A. But think il use 0.4 on everything now, which will equal around 50-60A for standard domestic ... I've learn from this thread.lol
