A few years ago I was asked by a home owner, one of our city's finest and his wife sold home insurance.
Why now does my celing fan run when I turn on the range but the range don't heat up all the way?
They had hired a cabinet maker to remodel the basement. when they asked him to recomend an electricial contractor who could increase the panel size.
Well the cabinet maker replied. I have a friend who can do it a lot cheaper and he is not working now.
When I went and checked the panel all the branch circut white wires were on the breakers and the blacks were on netural bar.
So I asked the owner who did this. I then proceded to check outside for the meter, it had not been touched he changed the main panel with the main taped up and reconeced the new one. He was not even an Electrician.
