Looks like a 20A to me. What on earth are they going to be running that couldn't have gone on a 15A circuit?
Paul, a lot of "home ent. centers" now feature high-powered, multi-channel audio receivers, satellite recorders, dvd players, satellite radio receivers, etc. The total draw on many systems just playing a dvd at moderately loud levels can overwhelm a 15amp circuit.
For the film screening rooms I install in homes, we have to have a
subpanel to handle the demands of the film projectors, video projector, sound rack and touchscreen automation as well as screen curtains and maskings.
Typical circuits used are(these are breaker sizes, not necessarily continuous loads):
2 x 20 amp, 120v film projector motors;
2 x 30 amp, 240v Xenon lamp power;
1 x 20 amp, 120v for Xenon lamp exhaust blower;
1 x 20 amp, 120v worklight and service recpt at proj. bases;
1 x 20 amp, 120v for video projector and lift;
3 x 20 amp, 120v for audio power amplifiers;
1 x 20 amp, 120v for audio source equipment and AMX controller;
1 x 20 amp, 120v for film inspection bench;
1 x 20 amp, 120v for screen masking motors;
1 x 20 amp, 120v for screen curtains.
Booth lighting is on a 15 amp circuit.
So in this case depending on what they're going to expand into (especailly if the LCD/Plasma TV is powered here) they're actually
underpowered!
