    Fire in the hole.

    Got a call the other day from a home where I installed two new twinned furnaces a few months ago.

    They said they smelled a burning smell coming from the unit. I get there and I can smell smoke also,
    go into the basement where the furnaces are, and basement is full of smoke, definite electrical smell.

    Quickly go cut power off to the house, come back and see the breaker box toasted.

    Turns out the 100 amp 3 phase breaker for the house elevator caught fire. Electrician had to
    replace the box, as you would guess.

    Home owner is very lucky fire stayed around electrical box.

    Lucky you got there quickly.
    Pull the meter?
    Have a picture of the inside of the box?
    Strange they didn't call the fire department.

    I was surprised they did not call fire dept either. I was close by when I got the call, so I got there in
    about 20 minutes.

    They simply thought the ac system was acting up.

    Outside they have electric meter in one enclosure, and a large disconnect with a big lever. I just pulled the
    lever down. This house has a sizeable 3 phase electric service.

    Here is a picture of the buss bar burned.

    Just goes to show that money can't buy brains.

    Who calls a repair tech while their basement fills with smoke?

    As I think about it. Pulling the meter would not have killed the power. Those 3 phase use coils for metering.
    Hence the disconnect.

    Pulling the meter would not have killed the power, because the meter uses the round donuts to read the power useage.
