i know exactly what you mean but i would rather give the option rather not give the option to do house work if i can, money is money and all that. also on the panel building there would be no standards has such because i build them them now for the odd cash job and so long has the parts used are...

twin compact hf ballast 80w so 160w a fitting switching is being done by contactors so nay bothered about switch current rating, and they will be split over 3 phases but just wondering what size breakers to put in.
