One of the pump/gate stations we looked at today had one of the funkiest electrical setups I've ever seen that was installed by supposed electricians.
The conduit work looked like spaghetti thrown all over the wall, and the actual service panel was totally hokey. The service entrance neutral (which was green wire rather than white) wasn't connected to the panel's neutral bar, it was connected to a ground bar and they were using the panel itself to carry current.
Damn. Pretty lame shit.
