Is it permissible to reduce the service neutral on a 200a 120/240v 1? service for site lighting at a commercial parking lot?
I would like to use URD 4/0-4/0-2/0 cable in my 2-1/2" PVC from the pole to the meter socket.
Most all of my loads are at 240v. The only 120v load is a 1500w heater in the control cabinet, the control power and a convenience receptacle.
What code article allows the reduction in size of a service neutral?
