Hey Guys,
For a service entrance rated switchgear, is the neutral bus and ground bus both bonded to the enclosure? I don't believe you would have a system bonding jumper like you would for a service disconnect in residential, for a switchgear where you have the ground bus spanning the length of the gear it would make sense to have the two busses bonded to the enclosure. The neutral bus would not be insulated.
We're talking 208V, 3 phase, 4 wire system.
Thanks,
EE
