Mayhem,
You're right. I thought he mentioned his pack could be loaded to 2400 watts total (20Amps). In which case it woud be limited to 1800 watts on a 15 amp
circuit. However, most outlets in commercial buildings are 20
amps will give out 2400 watts. His pack is most likly fused at 20 amps.
ALWAYS check the
dimmer for the rating. Never assume that the dimmer can handle 2400 watts on a 20 amp circuit.
