Adding circuit to existing conduit
I've got a conduit used for a 50A hot tub circuit. The conduit runs along the outside of the house to a small subpanel with a GFCI, then connects to the tub.
At some point I want to rewire my garage. I'm wondering if there's room in the conduit to run a 60A circuit to the garage. I would use the existing conduit up to the hot tub subpanel, then run a new conduit out the other side of the sub to the garage.
Just guessing, but the conduit is maybe 1-inch. Anyone have an opinion on whether there's enough room? Thanks.
