The ballast has a hot and neutral wire at one end to receive power, and two blue wires a red one at the other end to supply power to the lights.
What are the red and blue wires on a ballast?
The ballast has a hot and neutral wire at one end to receive power, and two blue wires a red one at the other end to supply power to the lights.
What is the black and white wire on a ballast?
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.
Which wire is hot on a ballast?

Originally Answered: What are the two yellow wire from a ballast for? The yellow wires are your commons/return paths on the output side. The yellow wires are your commons/return paths on the output side.
Can one ballast power two bulbs?
The two bulbs will always have slightly different impedances, so more current will flow through one or the other. It’s difficult to balance this out. The condition where one bulb is fired and the other is not is obviously the worst case for this.
What is the GREY red wire on the ballast for?
The gray/red wire is the return path for the second set of lamps. In other words, it is the neutral for the second set of lamps.
Can you use a 2 lamp ballast for 1 lamp?
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.Can you wire fluorescent lights in series?
Measure the distance between each fluorescent fixture. Cut a length of 14/2 nonmetallic cable (NM) that measures 12 inches longer than your measurement. Repeat this step for each fluorescent light you will wire in this series.
How do you connect two fluorescent light fixtures?Run a length of two-conductor wire from the existing fluorescent fixture to the new fixture. Loosen the screw on the side of the cable clamps on both fixtures. Feed the ends of the wire through the cable clamps and tighten the screws until the wire is secure.

If the ballast has no direct ground connection then you can use a blue (for #14 and #16 wire) stake-on fork on the stranded wire from the cord and attach it directly under the ground screw or you can wrap a short piece of solid green or bare #14 wire around the screw and attach it to the cord by a wire connector.
Can you splice ballast wires?
In the case of installing an electrical fixture, a splice is used to connect the lead wires of your fixture (it doesn’t matter whether it’s a ceiling fan, ballast, or downlight housing, they all have cable leads) to your house’s line voltage.

Can you run hid without ballast?
A ballast is essential in HID lighting technology because it provides the voltage to start the bulb and it also helps in maintaining an adequate flow of electrical current to the bulb. … Simply speaking, a ballast is essential if you want to enjoy the real strengths of HID bulbs.
How many fluorescent lights can you put on one circuit?
It’s possible to supply 48 lights with 40 watt light bulbs and still have a 20% safety margin with a 20 Amp breaker. When you only want to put 4 lights on a breaker, it’s unnecessary to have a breaker that is high.
Are fluorescent lights in series or parallel?
In fluorescent lights, each tube is in series with it’s own ballast; a dual tube fixture will have two independent ballasts in a single box.
Do Fluorescent lights need a ground?
The short answer is: no, they don’t need to be grounded, but it is way safer if they are. Many, if not all, electrical codes require installed light fixtures of all types to be grounded. The GREEN wire should be connected to any and all of the lamp’s metal or conductive structure that can be touched by the human user.
How do you wire a 3 way ballast for 2 lamps?
Cut and cap one yellow and one red or blue wire with a wire nut. Connect each of the blue ballast wires to the each of the two blue lampholder wires. Connect the red ballast wire to the third blue lampholder wire. Connect the yellow ballast wire to the red lampholder wire.
What is the difference between rapid and instant start ballast?
Rapid start configurations have two wires connected to each side of the lamp. There is a small voltage between the two wires that is used to provide heat to the lamp’s cathodes. … With an instant start configuration, a high voltage pulse is used to start the arc between the lamp’s cathodes.
How many fluorescent lights should be in a garage?
If you want the garage to have even illumination, reduce that amount by half. Four, 3-lamp fixtures should achieve even lighting over nearly all of the garage. If you don’t need to have the whole garage lit up, one or two of these fixtures should suffice.
Can you replace a fluorescent light fixture with a regular light fixture?
Sometimes, you want a light fixture with a little more pizzazz, or one that produces light that’s a little warmer than the cold, bright light that’s so common with fluorescent fixtures. Swapping out a fluorescent fixture with a regular, incandescent model is easy to do.
Where is the ballast on a fluorescent light fixture?
Locate the wiring cover plate, usually in the center of the fixture. On either side of the cover, there will be tabs that catch in slots in the fixture. Squeeze the sides of the cover inward to slip the tabs out of the slots, and pull the cover down. This will expose the ballast and its wiring.
How do you know what ballast you need?
It needs to fit the electrical requirements of the lamp that it will run. When purchasing a ballast, you’ll need to read the type of lamps it’s designed for, how many lamps it operates, and the voltage the lamps will run on. Choosing the right ballast for a lamp will optimize the light output and life of the bulb.
Does the ground wire have to be attached?
Grounding refers to the wire that runs from an outlet into the earth, inherently protecting homeowners from coming in contact with electric energy. No matter the method, it’s important that the ground circuit provides an unbroken path to the earth. Ground wires must be firmly connected at all points.
Why is my fluorescent light yellow?
Why do fluorescent lights turn yellowish when they are used for a long time? – Quora. There are several reasons for this. The phosphor coating on the inside of the tube deteriorates with age and so the quality of light output changes as the tube ages.
What is T8 vs T12?
The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.
