![]() ![]() I have read previous discussions about providing an EGC and grounding RV pedestals with a ground rod. What is the final verdict on the proper way to ground a loop feed RV pedestal supplied from a combination service device(meter socket/ panel with service disconnect)that is grounded at the transformer. The Pedestal is listed as "suitable for use as recreational vehicle site supply equipment". The neutral is not bonded to the metal frame and a separate ground lug is provided. Thank you.

![]() ![]() The RV ped is Service Equipment. Bond the Neutral and provide Earth and Plumbing bonds(if metalic pipe) at each space. The loadcenter within th RV itself is a Sub-Panel and has an isolated Neutral. The Feeder can be three conductors only with no Eq.Gr. conductor. IP: 66.118.195.217 |

![]() ![]() Correction: I just looked it up, I might have been wrong (it's happened before) check out NEC '02 551.76 (A) + (D) I'd get an oppinion from your inspector in advance. IP: 66.118.195.217 |

![]() ![]() Jim, Take a look at 551.76. RV Pedestals SHALL BE GROUNDED by a continuous EGC run with the feeder conductors for the pedestal row. 551.76 (C), The neutral SHALL NOT be used as an EGC. Having said all of this, ground rods at each pedestal would not be required, however after much investigation, in California for some reason, the AHJ wants ground rods at each pedestal and NO EGC run with the feeders. No matter which method is used, the neutral is not grounded or bonded at the pedestals. IP: 12.18.100.210 |

![]() ![]() "the AHJ wants ground rods at each pedestal and NO EGC run with the feeders. No matter which method is used, the neutral is not grounded or bonded at the pedestals." Talk about a dangerous setup if a appliance were to go to ground the earth would not provide a low enough impedance path to trip a 5 amp breaker!!! and the whole RV would be hot to earth!! could you imagine what would happen if a elderly couple touch the door and fell dead. guess whoo they would go after? the installer not the local AHJ. 80.29 Liability for Damages.
