Setup: 2x MPII in split phase configuration running to Autotransformer 100A for load balancing, feeding a main breaker panel in a shed. Neutral and Ground are bonded inside the main panel. The Autotransformer instructions say that the ground relay in the AT only should be used and the ground relay(s) in the MPs should be disabled. However isn't there only supposed to be one location where N and G are bonded? Since they are bonded in the main panel, does that mean none of the ground relays should be used?
