Our discussions with 2 separate NFPA staff on 2 separate occasions resulted in the same interpretation. Grounding electrode system required for the subfeed of mobile homes since they are a separate structure.
I have no problem with that. Ironically enough Mr. Sargent is quite respected in the electrical industry and believes otherwise. In many circles, Section 550.16 will provide for all grounding and bonding needed and as long as the EGC is properly sized and provided then I could say what advantage does the additional electrodes play at the mobile structure? Considering we are speaking in regards to issues with transient voltages and lighting mind you. We only need to venture into Section 250.34(B) to understand why vehicle mounted generators do not require a GES when all conditions are met to maybe understand the question...Will adding the additional electrodes at the mobile structure ( which is not installed on a permanent foundation ) benefit the safeguarding of that structure. I guess that is to be decided by the local AHJ at the time of inspection I guess.jar546 said:Our discussions with 2 separate NFPA staff on 2 separate occasions resulted in the same interpretation.
