How do you connect fluorescent lights together?
Attach the black wire from the last fixture to the black wire from the power supply using an orange wire nut. Connect the white power supply wire to the white wire from the last fixture with another orange wire nut. Connect the bare copper wires from the power supply and the fixture in the same manner.
Can fluorescent lights be wired in series?
Older magnetic fluorescent ballasts are usually rapid start and wired in series. Newer electronic ballasts are instant start (wired in parallel), rapid start (wired in series), programmed start (wired in series-parallel, dimmable and CFL ballasts.
What wire do you use for fluorescent lights?
Fixtures wire shall not be smaller than 18 AWG.” Once inside the fixture you can use #18 for not over 6 amps. It must be a type listed as fixture wire. Most Electricians would just use #14 and be done with it.
Can I wire 2 fluorescent lights together?
As long as the combined maximum amperage rating of all the fixtures combined doesn’t exceed the circuit breaker rating, you can install as many fixtures as you want. On a properly installed circuit, adding more fixtures is a simple matter of running and connecting additional wiring.
What happens if you wire a ballast wrong?
If a ballast fails, it can cause a short, burn out tubes or even cause a fire, so it must be replaced. Lights that don’t turn on, fluorescent tubes blackened near their ends, and brown, burnt tube electrodes are all indicators that a ballast is bad.
How many fluorescent lights can I put on one circuit?
You can put up to 30 lights (based on 50 watt light) on a 15 amp breaker. You can put up to 40 lights (based on 50 watt light) on a 20 amp breaker.
How do you connect two light tubes?

What does a choke do in a fluorescent light?
The choke primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive ‘kick’ forming a momentary higher-voltage pulse to start the lamp.
What color wires are on a 2 lamp ballast?
2 and 3 lamp instant start ballasts use blue wires for individual connections, and red wires for common connections. Black wire is for line voltage and white wire for neutral. An instant start ballast uses a single wire which connects from the ballast to each of the lamp terminals.
What are yellow wires on a ballast?
The common yellow wires connect from the ballast to push-in connectors on one of the right holders of lamp 1 or 2. Two yellow wires connect the common lampholders together.
How many wires are in a ballast?
Light Fixtures with Two Ballasts
The common wires of each ballast are connected to the other side of the fixture from each of the individual wires.
Which wire is hot on a ballast?
Generally, the hot wire on the ballast is black, and the neutral is white. The other colors are the wires that connect the ballast to the fluorescent tube holders and to each other.
How are fluorescent lights wired?
The tube just needs a voltage kick across the electrodes to establish an electrical arc. This kick is provided by the lamp’s ballast, a special sort of transformer wired into the circuit. When the current flows through the bypass circuit, it establishes a magnetic field in part of the ballast.
How do you wire a 4 wire ballast?
Quote from the video:
Quote from Youtube video: I said this is a four-wire ballast. You have your black inner right here.
Does ballast need to be grounded?
The fixture or ballast does not have to be grounded through an equipment ground to operate. Yes, the ballast case has to be electrically connected to the sheet metal behind the lamps for them to ignite.
How do you hook up a t8 ballast?
Quote from the video:
Quote from Youtube video: Take the stripper rip it off push it into socket locks in always check it here we have all four sockets on this side of the ballast.
