please, answer any way u like. Someone asked me to add some circuits to a 200A panel. After probing it under normally operating load, they were using about 183A. So I thought about bringing another service off of the main. When I looked at it, there was a 1000A main with 200A breakers going to five different units, including the one I was scoping. Now, my question is this: assuming all the other units are occupied and using their allotted power, even with an empty spot for another breaker, is there ANYthing that I can do to get more power to the unit where I need it??? Thanx in advance for easing my mind. Just trying to see if there's something or some way that I don't know about.
