Hello everyone. I have a technical question about doing the ground neutral bonding on a disconnect switch. This switch will be part of an inverter tied to the grid but to keep the question simple, I ask that you look at this as just adding a switch between the meter/grounding rods and the existing panel (formerly the main panel but will now be a subpanel).
The switch is a Siemens GNF324R. What seems to be causing the confusion is that it is a 3 pole switch and it did not come with a grounding kit or a netral kit. The sticker on the switch says that it is service rated when used with either HG61234 grounding kit or HN64 neutral kit. I was able to order the grounding kit for about $10, but the neutral kit is at least $100 and I was hoping to avoid buying it. It seems that a 2 pole disconnect with both ground and neutral termainsl would have been more straight forward, but I'm hoping to make the 3 pole swithc work since I already have it.
This is a 200 amp service. In the diagram, the brown wire is a bare copper ground. The white wiere is neutral. The black and red wires are hots.
Please see the attached diagram. Does it make a difference if the neutral wire goes to the grounding block on the line or load side? I realize that local jurisdiction may differ on whether it would be acceptable but would it be acceptable per NEC?
