Daniel Carruthers Posted September 5, 2007 Share Posted September 5, 2007 Hi I got a music video coming up and we are shooting in an old farm house. apparently the farm house only has one 120v circuit. So my question is how muck power can that circuit take, could it handle 2 650s? Link to comment Share on other sites More sharing options...
Bobby Shore Posted September 5, 2007 Share Posted September 5, 2007 hi, You definitely want to check the amperage of the circuit as well, which will give you a better idea of how strong a load it can handle. Chances are it'll be a 15 or 20 amp circuit, so yeah, you'll be fine with 2 650's. General rule of thumb: 1000 watts of power requires 10 amps on the circuit (it's actually 8.3 amps, but it's always safer to round up). Hope that helped.

Robert Hughes Posted September 5, 2007 Share Posted September 5, 2007 (edited) Keep in mind that the electrical service at a rural location such as a farmhouse may have significant distribution wiring losses; if you're counting on a full 120V circuit you may actually be getting something closer to 90 volts. Will your lights still strike and operate at that low voltage? You may want to bring a generator along as a backup.

Jonathan Bowerbank Posted September 5, 2007 Share Posted September 5, 2007 (edited) As already stated, it's amperage that you have to worry about the most. Voltage is a factor you use in figuring out how many amps your lights are using. Watts / Volts = Amps 2(650) = 10.83 120 So as long as you're on a 15 or 20 amp circuit, you should be fine.

Be sure to shed any existing loads in the house first, and bring some spare fuses. Check the location to see what kind. -- J.S. Link to comment Share on other sites More sharing options...
