    Hi

    I need to be very sure before buying any isolation transformer. Assume I want to buy an insolation transformer (24OV AC input and 110V output) Power rate is about 3300VA. So that means the load cannot exceed than 30A. Is it possible to run load about 20A with my isolation transformer running from my socket at home?

    Regards

    If I knew what country you are in, I might make a guess. I have no idea how your building is wired. In USA, the answer would probably be, "yes".

    20A at 110V will be 2200 va or 2.2KVA. Check the rating of the socket you want to connect, if it reads 240V /5A then you cant load beyond 1200VA. If it reads 240V/15A then you can load upto 3600VA.

    Sockets in the kitchen and bath room will have higher current rating.

    Better check the power rating of appliances like AC, fridge or Electric Heater. If the appliance reads 2.2KW and that works at you home then you could probably use those sockets for your 110V@20A transformer..

    If your mains wiring has the correct fusing and wire dimension you may do it. But I think that kind of current also will require high current socket. Can you tell us more what you are trying to do.

    Hi basically what you need is a source of power capable of supplying 15 amps, that is 3300va/240v =13.75amps. You can place loads up to 30 amps on the secondary side.
