Should a ballast have continuity?
If it shows continuity on all connections, your ballast needs to be sent in for a fast service. You will always get a small resistance reading through the circuit. A reading of 10 ohms or less is satisfactory. If there is a problem in one of the lines it will be obvious.
How do you ground a ballast?
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.
How do I test a ballast with a multimeter?
To measure it, set your digital multimeter to around a thousand ohms resistance setting. Connect the black leads to the white ground wire on your ballast. Afterward, test every other wire with the red lead. When you do this test, a good ballast will return an “open-loop” or max resistance.
Will a ballast work if not 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 I know if my T12 ballast is bad?
If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Flickering.
- Buzzing.
- Delayed start.
- Low output.
- Inconsistent lighting levels.
- Switch to an electronic ballast, keep lamp.
- Switch to an electronic ballast, switch to a T8 fluorescent.
How do you check continuity on a ballast?
How do you test a ballast with a multimeter?
How to troubleshoot electronic ballasts?
How to Troubleshoot Electronic Ballasts Step 1 – Disconnect the Electrical Power From the Light Step 2 – Remove the Protective Covering and Observe the Ballast Step 3 – Testing the Ballast Step 4 – Testing the Low Voltage Side of the Transformer
Can a T12 ballast be wired in parallel?
Parallel ballasts can only be wired in parallel according to the diagram on the ballast. Changing the wiring on a fluorescent light fixture from series to parallel, involves changing the ballast from a series to a . T8 lamps with a newer electronic ballast use about 20 – 30% less energy than a T12 magnetic ballast.
What should I look for when buying ballast wire?
Also, pay attention to what color each wire is, as same colored wires usually go together, but sometimes they don’t. Ballast wires are very small in size, so make sure your wire crimps or wire nuts are sized for small wiring.
How do you wire a 4 foot light ballast?
The DOE ballast ruling effective April 1, , prevents the sale of 4 foot and 8 foot lamp. Connect the ballast to the power from the breaker panel by wiring the black wire from the breaker panel to the black wire on the ballast, using a wire nut.
