Power Load & Circuit Calculator
Power Load & Circuit Calculator
Enter your fixture power and quantity, choose a supply, and we’ll calculate total load, current draw, and suggested circuits (with optional 80% headroom).
Tip: If you’re running mixed fixtures, calculate each group separately then add totals.
Total power = W × qty
Current (A) = Total power ÷ (V × PF)
Circuits needed = Current ÷ (Circuit rating × headroom)
