I am trying to install outlets and lights in my shed. I ran 10/2 with the intention of having a single branch circuit. After initial inspection, I was told I needed to install disconnect, sub panel, and grounding system. I stopped by an electrical supplier to see if I could do this without replacing the 10/2 with 10/3 and this was their suggestion:
Install 30 amp double pole in basement sub panel using the black and white wires as the two hots. Connect those to another 30 amp double pole breaker in the shed sub panel and then jump them to the two hot bus bars in the sub panel. This will leave no neutral between the two sub panels, is this going to be a problem? Do I float the neutral bus bar in the shed sub panel? Will two 8 ft grounding rods connected by #6 copper wire to the shed grounding bar be sufficient for a grounding system? Are the white wires in the shed circuits connected to the neutral or ground bar in the shed sub panel?
I really do not want to dig up the 10/2 and replace it with 10/3 but I would like to complete this project without violating any codes.
Thanks to all who help with these answers.
