Came across an ITE panel (20 Pace 40 circuit 200A) with three quads that are damaged due to heat on at least one leg. Worst one was EV breaker with 50A in middle and 20A on outsides - It started smoking when homeowner's EV charged at 9600 watts. The other one was combo of dryer and AC Condenser, and the third was induction cooktop with 20A/50A quad. The EV one heat damaged and it appears the socket/spring action was totally gone on one side and poor on the other (where the bus blade pushes into). The bus itself and the stabs are in decent shape considering its a mid 70s panel
Siemens is the correct breaker to use in this panel from what I understand ? I've only done a handful of Siemens panels - not as bad as GE but I don't like the breaker seating, usually feel loose.
So this was outside of the scope of the job - just did some investigating on the main panel after adding a heat pump outside - swapped out one Siemans and a two Bryant Quads for the customer as he picked them up. I recommend a panel swap to and exterior disconnect but I think they are tight on money.
Thinking one leg might be loose somewhere at main breaker or meter (aluminum feeders). Anyone have experience with Siemens/ITE - did the ITE have slightly thinner bus blades that might make a loose connection ? definitely seems like connection is loose and heat happens
