but when you’re generating that much power, working with equipment that uses that much power, you need a good ground. your generators can’t provide a very good ground, since they’re insulated from the ground, and you can’t exactly drive a grounding rod into the street… so what is a film crew to do?
bring your own ground, of course!
fire hydrants are big metal pipes that extend deep into the ground, and are one of very few bits of metal sticking up from the ground you can trust to be grounded
so you hook one of your camlock connectors up to a big clamp, you find a hydrant near one of your generator trucks, and you clamp your ground onto the hydrant!
