That area is over concrete? How far is the panel? You could potentially use wire mold raceways or try and tuck the wiring behind a molding if you wanted/needed to run a second circuit.Unfortunately I couldn’t upgrade the wiring, I’m stuck with one 20 amp,
Even if both heaters, the chiller, all the lights, all the pumps and power heads are on at the same time, it shouldn’t trip.
I’ll have to watch it if I add a frag system though.
