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.
Voltage Drop Calculator
Build power and lighting plans that account for voltage drop. Our voltage drop calculator helps you estimate maximum wire lengths based on gauge and load, so your LED installations shine from start to finish.
