Question:
Greetings,
Can you connect branch circuit neutral wires to a grounding bus bar that is mounted directly on the service panel enclosure?

Answer:
Hi Andrew,
Sometimes service equipment panelboards, especially on dwelling units, are suitable for use only as service equipment. This equipment can be installed only in the service position. In this situation, the neutral bus (grounded conductor busbar) is connected directly to the enclosure for the service panelboard. In this case, the neutrals and equipment grounding conductors terminate on the same busbar. There is usually a wiring diagram included on the equipment labels that shows where connections should be made. It is also typically addressed in the installation instructions. Hope this is helpful.
