Power Requirements
We require the same thing for power indoors and outdoors, unless you do not desire lighting. Lighting pulls the most continuous power. (40 amps, approximately)Basically, our power needs are this:
- Four light trees X 1200 watts per tree = 10 amps per tree. We can put two trees on an isolated (separate) 20-amp circuit, and operate normally.
- Two amp stacks X 2400 watts per stack = 20 amps per amp stack. We will need two separate circuits for the amps.
- Fog machine = about 800 watts (close to 10 amps). This can be combined with the band power.
- Band power - powers assorted instruments, sound board/effects, and small on-stage amps. Usually can run everything with no problem on a single 20-amp circuit.
Outdoor Concerts
If you elect to have a concert outdoors, that's great! Outdoors is common ground, unsaved people generally feel less intimidated at outdoor events. We will need the same power for outdoor concerts as for indoor concerts. Generators are acceptable, as long as they have sufficient 120-volt connections and wattage. We have a power panel setup which allows us to tap into 220-volt commercial generator power and provide ten 20 amp breaker-protected circuits when a commercial generator is provided. If you elect to rent a commercial generator, plan to get one which is rated at least 12,000 watts (100 amps @ 120 volts). Please feel free to ask us if you have any questions.
Summary
We need five separate 20-amp circuits to run everything including lights. When I say, 'separate', that means nothing else plugged in on the circuit anywhere else! Refrigerators, fans, air conditioners on the same circuit will not only pull power down, they can introduce a loud 'huuummmmmmm' on the system.
