  1. Patrick says:

    I have a 125 amp main lug panel that was used as a main breaker panel fed by a 3 wire feeder. I notice that the neutrals and grounds are all sharing the same bar. How do i know when neutrals and grounds should be seperated in a panel?

  2. Dave Rongey says:

    The neutral and grounds are terminated together at the main electrical panel where the grounded conductor(s) from the ground source(s) is located. If a sub-panel circuit is fed from the main electrical panel, then a four-wire cable is installed containing a separate neutral and ground wire. At the sub-panel the neutral and ground are not bonded, but terminated separately. If the sub-panel has a jumper or bond between the ground or the enclosure to the neutral terminal strip then this bond or jumper must be removed thereby providing separation between the ground and the neutral.
