Electrical / Power question (Help!)

I wasn't sure which forum to put this question in so here goes. I'm not too familiar with current and electrical concepts so maybe one of you can help me.

 

Whenever there is a light (small or large switch) in my office or even in the room next to my office that gets turned on / off, if I'm listening to music on my head-fi setup (in office) the music/power gets interrupted for a split-second. Most of my gear is connected to a large battery backup surge protector. Even when I have taken my amp or dac and plugged it straight to a wall, the same thing occurs. It's VERY annoying. Does anyone know what could be causing this? Only guess i had is maybe the circuit breaker isn't powerful enough for all the electronics in here? I think currently it's a 20A breaker. Please help if you have any clues.

I think you may have loose or oxidized connections on either the breaker and or the receptacles. If the resistance increases and the current surges, the voltage will dip. If it doesn't stay low, it will bounce your regulator relay and you will get short dropouts. Those battery backups aren't re-generated supplies so any decent change in supply voltage will have some impact similar to what you describe.

Put a voltage meter on your receptacle and activate the switch. See how low the voltage drops. If it drops more than 5%, have an electrician review your power wiring circuit.

Thanks for the info! Great idea about the voltage meter. I'll check it out.

Hmmmm, I wonder if you have a dead battery in your "Battery back up surge arrestor"?

If it does have battery back up it should kick in and let you listen to your music uninterrupted if everything is plugged into it.

Check the batteries with a voltmeter.
