How do you wire a single phase 480 volt starter with a photo cell for lights?

Answer 1

You will not be able to use the line voltage to operate the photocell directly as the photo cell is usually rated for 120 volts or in some instances 240 volts. You will need a step down transformer 480 to 120 volts. The starter will also need to have a 120 volt coil. The black and white wire of the photo cell connects to the output of the transformer and the red wire from the photocell goes to the starter coil. From the neutral terminal of the transformer a wire is taken to the other terminal on the starter coil. The transformer should be about 50 VA.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.
