How to Calculate Circuit Loads and Sizes
[ad#block]I’m installing basement lights, how do I know how many light fixtures I can place per circuit and what size breaker do I use.

This electrical question came from: Larry, a Homeowner from Hebron, Ohio.

Thanks for your electrical question Larry.

### How to Calculate and Determine Electrical Circuit Loads for Lighting Fixtures

• The electrical circuit calculation for light fixtures is based upon:
• The number of lights that will be installed
• The size of the lamps
• The total number of lamps.
• Once this information is determined then the lighting circuit may be sized consisting of
• the appropriate cable
• and circuit breaker.
