Transcription notes
Product number: 1105-105 (control 1201-17-1). Floor area: 48 sq ft. Manual lists total amps 43.8 A, breakers 2 × 30 A (heater) + 1 × 15 A (control circuit to contactor box), and wire 4 #10AWG+GR; it does not allocate amperage or wire per group. Single phase heaters are supplied power from two circuits which must be grouped and marked per NEC; system needs a separate 120 volt circuit to power the contactor box.
