Ok, ok, you guys have me laughing. I'm going to pull the panel apart this evening when I get home. I was just going to Lowes on the way home and wonder if anyone was able to tell me which model that panel was. I was not sure if there was any sticker that said what it was.
I didn't want to leave the house without water or A/C to take the breaker to the hardware store to figure out which breaker it was, but if it needs to be done so be it.
Why 100a.... why not? Its all I need in my garage.
Panel leans a bit, but will be fixed once I begin the work on it. There will be no city inspections on this project, just a licensed electrician over my shoulder the whole way.
The subpanels I buy are all Square D. Bought this house a few yrs ago and when I bought it the panel was leaning then. When the inspector saw it then he said it needed to be fixed. They put a screw in it and called it a day. That's why I say it will be fixed right when I'm adding a subpanel. It's while your in there kind of work.

The whole area needs to be cleaned up and will get done. This is the first major project that I have been able to afford to do to this house. In the past history of this house it has been abused and not taken care of. My wife and I slowly fixing it up to where we like it to be.
I really appreciate the help and the comments. Thanks everyone.
