2 lamp ballast wiring diagram unique wiring diagram collection.
One lamp ballast wiring.
A wiring diagram is a simplified standard photographic depiction of an electrical circuit.
The yellow wires are for lack of a better description are shared so pin 1 of lamp 1 and pin 1 of lamp 2 go one yellow wire.
Here is how a 2 lamp ballast is wired to a 1 lamp fixture.
If one lamp fails the others can keep operating as the circuit between them and the ballast remains unbroken.
Ps make sure when you do this the power is off.
Connect the neutral conductors all together under one wire nut.
A 1 lamp rapid start series ballast can be hard to find but it can be replaced with a 2 lamp instant start parallel ballast.
Both ballasts should be tied to the ground wire that is in the supply cable.
1 lamp rapid start ballast.
When a parallel ballast instant start operates multiple lamps in a circuit the lamps operate independently of each other.
Wiring this can be done a number of ways.
You simply connect up the lamp sockets tombstone with the red and a blue and wire nut off the other blue.

If you had a double lamp fixture with it s double lamp ballast and two lamps hooked up and running and then one of the bulbs burned out early the other one would still work fine.
In a series circuit voltages.
The ballast blue wires connect to one end of the lamp the red wires connect to the other side.
Variety of 2 lamp t12 ballast wiring diagram.
Tie all three under a single wire nut.
The common yellow wires are capped with small wire connectors.
Is this how you have it wired.
If you are still confused there is a wiring diagram on the ballast which can help you.
It reveals the components of the circuit as streamlined shapes and also the power and also signal connections between the devices.
So the present flows via one part to obtain to the next one.
Confirm that the new ballast matches the old one photo below and then install it as shown in photo 4.
