It is a violation of the NEC to ground the neutral and shore power in the rig. Shore power is only grounded at the service connection point. The genset must have the neutral bonded to ground.
Really. I have worked on motorhomes and Gensets for 40 years. The 120 pigtail coming OUT of a Genset for 50 amp and above Gensets. Has 4 to 5 wires.
2 wires are the Black HOT output
1 or 2 wires(depending on the Genset) are WHITE Neutral wires
then 1 wire is the ground output.
ALL go straight to the ATS or the 50 amp female receptacle(if no ATS system). At no point is the Neutral grounded. The Neutral wire goes straight to the inside 50 amp breaker panel from the ATS system to the Neutral BUSS Bar. The GROUND goes straight to the GROUND on the Inside Breaker BUSS bar. At no time are the Ground and Neutral connected. I am NOT an expert on the NEC or how it relates to RV systems. ALL I KNOW, is, HOW 120 systems are connected and used in RV's. ALL RV's have a separate Neutral BUSS Bar and a GROUND BUSS bar.
Last, ATS systems do NOT look for true 50 amp out of phase HOT to operate. 50 amp EMS systems do. Doug
