I am building a new Red Iron Garage. I am wanting to know about wiring. I would like to run 3/4" or 1" conduits from where my panel will be located, under slab and stub up in each bay in the walls. I will be lining the walls with metal. I would like to run the electric behind the paneling in conduit instead of having it run on the outside of the paneling? What are your thoughts on this?
