The word on the street is to use the "first" box on the circuit -i.e., the box that, when disconnected, kills every other box fed by the particular fuse or circuit breaker. This is as close to having a "dedicated" circuit in an apartment as you can get.
Dedicated circuits...am I missing something?
As I live in an apartment, I don't think that the management would take too kindly of rewiring the place! However, if I am able to unplug/turn-off all other electrical equipment on my sound system's circuit breaker, then haven't I created a dedicated circuit or am I missing something?
