For location shooting, power will often take the form of a gas-powered generator. Generators can be AC, DC or both and can range in size from small portable 30 amp units to towaways the size of tractor-trailers. Be sure to rent a generator that comfortably accommodates your power needs. A high capacity generator is typically quite affordable to rent and simple to operate. A common misconception is that generators should be grounded. The modern line of thinking is that it’s actually safer to let the generator housing act as a ground. The only time to actually ground a generator is if local ordinances require it, or you’re working with a combination of generator power and facility power, in which case you should tie the generator ground into the facility ground to avoid any potential difference between the two.
