    Generator back up for house

    Not so much an electrical question, but physically. Got a customer out in the sticks who’s suffered with powercuts frequently during the recent storms. Now, easy enough to fit a changeover switch, but in this case, the mains comes in in the centre of the house. Not a handy place to drill a hole...

    Wiring a generator transfer switch

    Ok. So my generator is a duromax 12500 dual fuel. I want to wire it to my panel. I know I need a transfer switch. Here is my dilemma. The bozo that wired the house put about half of what I want to wire to the transfer switch on a 50 amp sub panel. So basically half the house is on the 200 amp...
