Electrical system in our now 70 year old house had a 100 amp fuse box. In order to install AC, we up-graded to a 200 amp circuit breaker panel (see photos), retaining the fuse box as a sub-panel. Breakers in the panel currently include: 50+50 (fuse box), 40+40 (AC), 20 (Kitchen appliances), 20 (fridge), 15 (garage lights), 15 (garage power), and 15 (misc.) = 245 amps worth of breakers. Of course, we never have all of those maxed out at the same time. I think most of those circuits would be at less than rated capacity even if every power draw on the circuit was active at the same time. An added issue is that light sthroughout house dim briefly every time AC comes on.* I would like to add another 20 amp circuit to run a 10-gal water heater. How do I determine if it is safe to add the new circuit?
*AC is new, has done this since install, and previous one did the same, so AC not the cause.
