A hot tub with an 11-kW, 240-V
heater and a 240-V motor that draws 6A is located
80 feet from the main distribution panel. On average,
the heater and motor will
operate 3 hours per day. Prepare a paper dealing with
the advisability of using
heavier gage conductors than required by the NEC. Using
prices for electric energy
and materials in your area, estimate how long it would
take to recover the
additional cost of using one size larger conductors for
this hot tub installation. Visit
this website for some ideas to help you get started.
