Fixture Wattage Calculator

Calculate total wattage and current draw across a lighting circuit to ensure you don't overload dimmer switches or branch circuit breakers.

1. Fixture & Bulb Quantity

2. Circuit Draw Results

80% Dimmer & Breaker Rule
TOTAL CIRCUIT WATTAGE
720 Watts
CURRENT DRAW AT 120V
6.0 Amps
DIMMER SWITCH MINIMUM RATING
600W Standard Dimmer
Load Capacity Safe: Total load is well within standard 15A lighting circuit capacity (1440W max continuous).

CEC Section 30 Lighting Rules

  • CEC Rule 30-104 requires lighting branch circuits to be rated no more than 15A or 20A.
  • Replacing old 60W halogen or incandescent bulbs with 9W LED pods reduces circuit energy draw by 85%, freeing up capacity on older lighting runs.
  • LED dimmers require explicit LED/CFL compatibility (ELV or TRIAC rated) to prevent flickering and buzz.
