Yup, another subpanel wiring question!


Ok guys, learning a lot from you all. So I have my detached garage with a sub panel in it. It has two hots and a neutral from the main panel. No ground run. (I know this isn't 2008 code as I have learned on here). At the main panel, the ground and neutral bars are connected by the bonding screw (Cutler-Hammer) and it has a grounding wire going to a ground rod.

At the subpanel, the set up is the same. The ground and neutral bars are connected via the bonding screw and a grounding wire running to a grounding rod.

So, is this correct? I have read so much on here about the 4 wire feeds, but very little on the 3 wire feeds. Thanks for any answers.

Yes this is correct, as long as there are no other metallic paths back to the house. This can be a metal water line, or phone or tv cable.
