Part of the equipment I'm bonding is a wire reel with a large clamp on it, the clamp is connected to the plane to drain static. It was my assumption that the static came from the plane but thats wrong. The static comes form the fuel being pumped thru a filter.The filter housing is metal but its lined with plastic. In this case the fuel won't be pumped so fast(10 or 12 gallons a minute) but generally jet fuel is pumped at 200 gallons (or higher) a minute. Once I talked to the engineer he thought about it for awhile and he decided the most important thing was to bond everything and forget about the ground rod until he(we) come up with the answer. Apparently he has done this many times with the rod. [Linked Image] I'm going to try the states head electrical inspector and see what he says. The place isn't open yet so I have time. Bringing a piece of #6 back to the service wouldn't be very practical at this point and it was one of the first things I suggested.
