West Union, Illinois | GregWCIL - ... proper way to ground a big generator on a portable drone trailer. I'm not sure the question has been answered. All the replies so far are for connecting to a structure. But when I read "generator on a portable drone trailer" I do not interpret that as connecting to a house or other building. I read it to mean JUST that trailer. That OSHA publication doesn't address that. Well, actually it does if you read it properly.As per OSHA, a generator frame need not be grounded with a copper rod and can act as the ground itself if it is separately derived and meets the following requirements:- If the generator only feeds power to electrical equipment mounted on it or connected to it by extension cords and plugs through power receptacles mounted on it.
- All the metal parts that are not designed to carry any current, such as internal combustion engines, the fuel tank, and the generator housing, are bonded to the metal frame.
- Equipment grounding conductor terminals, forming part of the power receptacles mounted on the generator, are also bonded to the frame.
If all of the above conditions are met, the generator’s frame acts as the ground bar and eliminates the need for a separate copper rod. If the above conditions are not met, then a separate grounding rod is a must. Read the last sentence again: If the above conditions are not met, then a separate grounding rod is a must.
