Your ballast is a tri-tap meaning it is tapped for different supply voltages.

The bars and squiggly lines are the transformer

Here is the Primary side

Locate the wire that is stamped 120v. This wire is connected to the HOT side of the power supply. In Canada this is the black wire from the wall/house socket. US should be the same. So wire your plug and extension wire the same so the 120v wire from the ballast connects to the hot side of the wall socket(black).

Locate a wire called COM from the ballast, this connects to the WHITE side of the wall/house supply. Wire this correctly to the wall socket (white)from your plugs and extension wire.

Clip off the other wires from the ballast primary side that are labelled 227, 208 etc. These are not needed, but ENSURE they can not short circuit anything. Wrap them in electrical tape.


Secondary side

Locate another wire labelled COM from the ballast and connect this to the lamp mogul socket. It should be connected to the socket so it is connected to the outer portion of the bulb socket (common side).

Connect the wire labelled cap from the ballast to the capacitor.

Connect the other wire from the capacitor to the mogul socket so it is connected to the bottom portion of the bulb(Hot side)

When you package your ballast in a case you SHOULD also ground the case, using the green wire from your wall/house supply. Quite often it is the bare wire/green wire that conencts to the outside of the wall socket.
