My father in law had a metal shop built. Metal framework and sheet metal roof and sides. Now he wants me to help him run electricity to it. They did not install a ground rod through the slab, but did stub up for electrical conduit. Here is my thoughts and let me know if this is correct. Connect 6/3 UF wire to 60 amp double pole breaker in the house breaker panel. Run in PVC conduit underground to new breaker panel. Remove bonding screw. Install grounding rods outside of Bldg. Connect wire from Ground rod to Ground buss. There will be no other lines connecting the buildings.

Here's my questions. Does the Ground wire to the rod needs to insulated or not? If I leave it uninsulated it will it bond the building to the ground. Should I install the service panel on 2x4's or can it touch the metal studs? I plan on using metal junction boxes and rec. boxes, Is there any special attention needed for those?

You could sleeve the UF where it enters and exits the ground. There is no need for UF to be in conduit unless to protect from physical damage. Individual conductors in conduit is much easier.

Yes you will need a ground rod at the outbuilding. The grounding conductor does not need to be insulated.

At least #10 copper, green or bare. I don't like pulling bare wire in conduit, but #10 isn't that bad for a short run.

Will I still need to ground the metal boxes, if I'm screwing it to metal studs? What about the breaker panel can it be mounted to the metal studs or does it matter?

Yes. You need a pig tail from the metal box to the receptacle. Screwing the panel to the metal studs is fine. However, I would use a back board. This way you have a way to secure the conduits or cables as they leave the panel.

So will it be ok installing the panel to the metal framework of the building? Or does it need to be framed out with 2x4's?

Please explain more about what you are doing.

You will need 4 wires from the main panel as you must pull a ground as well with the circuit. And in the sub panel you will need to isolate the neutral buss from the panel, and bond the grounding buss to the panel. And the grounds and the neutrals need to land on their respective buss. The length of the run will determine the circuits wiring size at any given ampere rating.
