I'm having some issues with the circuit breaker in my home theater room tripping. Here is a list of what is hooked up:
Panasonic 50" plasma
Pioneer Elite sc-35 receiver
Pair of Def Tech 7002 towers
Pair of BPVX rears
C/L/R3000 center channel
Supercube I subwoofer
Xbox 360 elite
comcast HD cable box
Everything but the sub is plugged into a monster Powercenter HTS 1600, while the sub is just plugged into a nearby wall outlet on the same circuit for now. There is also some recessed lighting as well, hooked up to a dimmer switch.
The ciruit breaker is a 15a AFCI I believe.
There is also another tv set up next to the home theater on the same circuit, all hooked up to a cheap power strip, but I usually turn off that power strip when it isn't in use. That setup consists of a 50" DLP, nintendo Wii, and the old PS3.
The issue I'm having is that the circuit breaker seems to trip randomly. I could go weeks watching movies and playing games at high volume with no issues, and then one day the circuit breaker will trip, sometimes even when I'm just watching a tv show at regular volume. I'll reset it, and usually it will trip again and again until I unplug something, like the sub or the towers. I'll come back the next day, plug everything back in, and it might work fine for weeks. It has always tripped after the gear has been on for a couple minutes, and never has tripped while in the process of turning everything on. I've even had the other tv and ps3 on along with my entire home theater, and won't have any issues. I haven't noticed any patterns as far has having lights on or off either.
I realize there is a lot hooked up to the circuit, but I have a hard time believing it is just overloaded when it seems to trip so randomly. I would think if it was overloaded it would be tripping while turning stuff on, or only during loud parts of movies, or during times when the sub is going crazy, but not when I'm just watching a TV show with everything but the tv, receiver, and cable box turned off. I'm by no means an expert, so I may not really understand whats going on though.
Any help would be appreciated. Let me know if more info is required.
