Western Electrical Contractors Association (WECA) 103 Practice Test

Using 150 VA per 2 ft of track, what is the track lighting demand for a 6 ft length?

300 VA 600 VA 900 VA 750 VA

Correct Answer:

750 VA

Explanation:

Track lighting load grows in direct proportion to the length of track. The rule is 150 VA for every 2 ft of track, which means 75 VA per foot. For a 6 ft run, multiply 6 ft by 75 VA/ft to get 450 VA. That is the demand the track would impose. The options listed don’t include 450 VA, so none match the calculation. If someone instead treated the length in a way that yields 750 VA, that would not align with the stated 150 VA per 2 ft increment.
