Hi George,
Good to see you here again. I was looking this up as you posted.

I will take exception with your overkill opinion. I got the same argument from an HVAc tech on site. I happened to be near when he got a phone call, left the area of the condensing unit to talk, and I flipped the breaker back on (then off again). When he came back, he walked straight back to the unit and started to work. I told him to stop working because dead guys aren't allowed to service AC's. I explained what I had done.

Anything can and does happen on a job site. A fusible disconnect is as foolproof as you can get. Breakers are mechanical items. Sometimes they fail. Or they can be reset without the knowledge of the worker they are supposed to be protecting.

DO NOT LET THIS GET AROUND, but occassionally the guys in our City do the right thing. This requirement is one of them.
