In my situation the Nat gas and fies box are far apart. I'm installing the generator near the nat gas and running wire to the fuese box where the transfer switch will be.
Its a 15kW unit so large (#2 minimum) wire will be needed to carry the single phase power to the transfer switch.
I'm having trouble finding this in a bundle. Will I have to run individual wires in a conduit? The run is ~140 ft.
Where's a good source for electrical wire of this size?
