fxdude, It looks like you've got the room for an additional 30A ckt. based on what the panel label says. The number of breaker spaces available does not mean you can slap a 100A circuit breaker in (like brew_ny said). When you calculate your load, some are considered continuous (hot water heater) and others non-continuous (A/C). If the new circuit is for a brew rig, it's considered non-continuous. There's probably an electric meter room that will have electric meters and panel disconnects for each occupancy panel. You could probably ask the property management people (or the property super) what the panels are rated for. Contractors, especially in areas like Hollywood and New York have to charge more because the cost of living/doing business there is higher (license fees, insurance, accountants, rent, etc.). I think it's a little on the high side, but not sore butt bad. It's better to let a licensed guy do the work and not have to worry. If you choose to do the work yourself, don't do it alone. Have someone there to help if you get hung up on the circuit or to call 911. Pete
To add to what grathan said; 10/3 romex is about 1$/ft. you can buy shorter rolls if you want. I always like the additional wire in there in case you need it. The added cost will be insignificant (10/3 vice 10/2)
