Problem
Camera lights draw enough power that a circuit breaker trips during a multi-camera production.
Solution
Root Cause / Diagnostic:
High-output studio fixtures (COB lights, softboxes, hair lights) combined with computer power supplies on a single residential or commercial 15A/20A branch circuit exceed the circuit breaker’s continuous 80% thermal trip threshold (e.g., 1440W on a 15A 120V breaker). When all key lights are turned up to 100% intensity, the prolonged draw creates resistive heating in the bimetallic strip, ultimately snapping the breaker mid-broadcast.
Actionable Fix:
1. Calculate the total cumulative wattage of all lights and production gear, ensuring no single 15A circuit exceeds 1,440W (or 1,920W on 20A circuits) under continuous operation.
2. Distribute lighting gear across distinct, verified wall circuit breakers using heavy-duty 12 AWG extension cords to branch off to separate circuits.
3. Test all studio lights simultaneously at 100% output along with all production PC/monitor loads for 45 minutes prior to broadcast to confirm thermal circuit stability.
Pro Tip:
Label your studio wall outlets with their corresponding circuit breaker panel numbers, and keep a clamp multimeter in your gear kit to measure real-time amperage draw before locking in lighting setups.
