I spoke to Duquesne light since I am considering a service upgrade.

Kinda surprised!

All existing Triplex is cleared for 200 AMP service and they really
dont care what you do.

I have pulled meters, broken fuse, stuff like that twice. they said
pull meter if you know how safely just let us know so we can reseal it
when you are done.

basically they sell power and dont care as long as you are paying for
it legit......
