Pardon me while I become wishy-washy...
Saw the panel today, a 6 circuit 125A MLO (GE), you know, the type with the 8 circuit bus that has two "poles" blocked off...
Joe was trying to put a two pole breaker in the wrong spot, he thought he'd bought an 8 space MLO panel, and he forced a breaker where it was NOT designed to go, and broke a tab holding the left bus in...
I didn't have to scold him after it all came to light... He was feeling rather sheepish...
No other problems with GE...
