i have a small catering unit in garage conversion at home here in the uk, 3 phase is way out of my price range and i need a bigger oven i have a 3 phase one that is 7kw per phase and i can get it converted to single phase it is 4 deck and if i had all decks on ive been told it would need a 72 amp supply yet the whole house/garage is on a 60 amp main fuse,would the electric supplier up my supply and change the amps or would a 3 phase generator be better or maybe an inverter, the oven itself is a tom chandley convection oven and has no motors or blowers just top and bottom heating elements thanks to all the yahoo expert users who answer the questions

your electrical service needs to be updated unfortunately it is at your cost
