Dedicated circuit with 15 amp breaker.

[TABCON]

I just had this installed. The dedicated 15 amp circuit runs directly to the Gray 600 and from there to the receiver, the projector, the sub, the dvd and the satellite receiver.

Is 15 amps enough? The guy that installed the system said I should get a 20 amp breaker. Is he full of kaka?

I ran two separate 20 amp circuits to a conditioner. for my system.
My sub is on one all by itself.
A test to see if your need to go that big is:
Check to see what your full load amps and or watts will be.
By totaling each components wattage.
The only problem I see is, if your are drawing too much current, you can't just change a 15 amp breaker to a 20 amp. Unless 12 AWG wire was used.
With a 15 amp breaker, 14 AWG wire was most likely used.
It's against the NEC, and not safe. The max ampacity of 14 AWG wire would be reached, well before a 20 amp breaker tripped. I hope this helps. Rick

Unless you have a mega projector you will be fine. The projector is th eone that will use pretty much constant power with its bulb. The audio will be at low power most of the time and the peaks don't last very long. Satellite is minimal as is the DVD player, maybe 20 watts.

My DIY 15" Tumult sub driven by a Mackie M1400 pro amp will pop its dedicated 15A service when tested with short 5 sec duration sine waves reaching for SPLs above 110 dB. Can not test the max possible SPL out of the sub . But it provides enough bass during DVD playback in a 7000ft^3 room .

Actually, the size of the breaker is determined by the gauge of the wire. The idea is that the breaker opens the circuit in the event of a short. A heavy gauge wire can draw a lot of current, whether shorted or in use. The correct breaker will protect in the event of a short and will not open during peak load.

I ran 8 AWG wire to my amp and it's protected by a 30A breaker. 12 AWG can safely use a 20A breaker.

It should. Doubt those LFE peaks are 5 second duration, right?
