I went to a friend's house today and he had a problem with a circuit in his basement. It was easily fixed by replacing a receptacle. But, upon further inspection of his panel, I was slightly baffled.
Someone had taken a 200 Amp Siemens load center and converted it to a 100 Amp panel. I know this is kinda common, but the way it was done had me a little confused. They completely bypassed the Main Breaker knockout at the top and used a 100 Amp breaker in spots 1 and 3 to feed it. The spot where the main breaker was supposed to be was not knocked out so there is not live parts exposed. I just can't seem to find anything in the code that covers this type of installation.
Can anyone give me a clue if this is allowed? And the applicable article to look at for reference?
