Generator Grounding -
Generator Grounding -
The generator frame only should be grounded and it probably is already if it is bolted to a concrete slab with re-bar. However, in order to do the electrical grounding, you must take a look at the transfer switch. If the neutral is solid and does NOT open at the transfer switch then DO NOT GROUND THE NEUTRAL at the generator. The grounding for the generator is already in place from the main electrical service. DO NOT install any bonding jumpers from the neutral in the transfer switch either! It is not necessary to perform any further grounding.
However, if the neutral is switched in the transfer switch, then it is necessary to bond the neutral to the ground at the generator and also bond to a grounding electrode.
