2 different AC voltages on 1 circuit

  1. Sep 2, 2011 #1
    Hi, I have a Mains AC 251v to 220v transformer connected to my house.
    I am thinking of installing a solar power grind in system rated at 240v output.
    What would happen to my mains transformer if i connect the 240v supply to the secondary side at 220v of my wiring therefore having 2 different voltages on the secondary and at the same time using my mains transformer as a step up and down at the same time.
    Am just not to sure!

    If you have to ask, you shouldn't consider messing with this kind of power.

    Don't mix voltages, and don't DIY.

    Hire a licensed electrician, and discuss the matter with the utility which supplies one's home.
