Load Wattage

NEC Article 411: Low voltage circuits limited to 25A max (300W @ 12V, 600W @ 24V).

Wire Gauge Limits: 10 AWG for >20A, 12 AWG for >15A, 14 AWG for ≤15A.

Nominal Voltage indicates the output voltage at each tap of the power supply. If Dimming is selected, the value reflects the reduced voltage caused by the dimmer.
