I'm looking at my existing breaker box (circa 1975) as a prelude to mapping everything out (i.e., which outlets, switches, etc. map to which breakers) before I get a new outlet in the garage for charging my S, and found I have some which I can't really identify what they do.
I have two pairs of breakers that are 2x60-amp ganged - that is, each is effectively a 120-amp breaker, for a total of 240 amps (see picture - they occupy numbers 25-32). Considering the master breaker for the box is only 200 amps, that seems like a lot.
The major users of electricity are already mapped out (heat pump, fan, dryer, lights, etc). I have no idea what these do. I know when I bring an electrician over to give me an estimate, they'll probably be able to tell me, but I'm curious.
My plan is to get two estimates - assuming all the breakers in the box are actually in use, how much for a new breaker box with an extra for the charging outlet, the other estimate would be keeping the existing box and adding the charging outlet to the dryer circuit. I can deal with not using the dryer while the car is charging overnight.
Of course, if one of the mystery breakers is truly not used, then I don't need a new box.
Anyone have an idea what these might be used for?
Thanks,
Doug
