Instructions to Wire a T8 Ballast
A counterweight is an electronic gadget that controls the current required to light up a fluorescent cylinder. T8 weights are intended to cooperate with T8 bulbs, which are normally found in 4-or 8-foot lengths. Wiring an immediate substitution T8 balance can be moderately clear, despite the fact that retrofitting another kind of installation, for example, T12, might be additionally testing. Notwithstanding whether you are wiring another apparatus or retrofitting a more seasoned, existing installation, consistently ensure there is no voltage present and keep up a protected workplace. 2 lamp t8 ballast wiring diagram
Mood killer the breaker that provisions capacity to the circuit you’re chipping away at.
Evacuate the focal point, if present. Expel any bulbs inside the apparatus. Take care not to break the bulbs. Fluorescent cylinders contain dangerous synthetic substances. On the off chance that any of the bulbs are flawed, discard them as indicated by your city or province guidelines on risky waste transfer.
Expel the lodging of the weight. Regularly, the counterweight lodging is a bit of metal held set up with little tabs. All that might be important to evacuate the lodging is to physically crush the sides of the lodging together to discharge the lodging from the tabs. Different styles of lodging may require the expulsion of at least one little machine screws or hex screws. Utilize the suitable size driver bit and a cordless driver, or utilize the fitting hand instrument, to evacuate any tightens holding the lodging place. Try not to dispose of the lodging.
Hold a non-contact voltage analyzer beside the majority of the wires in the apparatus to guarantee that there is no voltage present. In the event that you discover voltage, watch that you have killed the right breaker. A partner might be important to flip breakers for you while you test for voltage.
Retrofitting an Existing Fixture
Expel any wire connectors from the high contrast circuit wires originating from the electrical box to which the bright light is mounted. These are the wires originating from the roof or divider giving 120-V control from the house board. Likewise expel any wire connectors that might be available between the old stabilizer’s wires and the wires prompting the light attachments. These wires are frequently red, blue and yellow. The accurate blend of wires will rely upon the kind of counterbalance that was available in the apparatus.
Check the kind of the first stabilizer. On the off chance that you are supplanting a T8 weight, the wiring of the old stabilizer ought to be equivalent to that on the new counterbalance. In the event that the old counterbalance was an alternate kind, the wiring in the apparatus, including the wires prompting the attachments, may should be supplanted or adjusted. The attachments themselves may should be supplanted. In the event that you are uncertain about the similarity of the apparatus and your T8 counterweight, counsel a lighting specialist. 2 lamp t8 ballast wiring diagram
Expel the old counterbalance by retreating the mounting sinks holding the stabilizer place. These screws may have nuts connected or the screws might be strung into tapped openings.
Check the situation of the mounting screw openings of the new stabilizer against the situation of the gaps on the old counterweight. In the event that the gaps contrast, drill and tap new openings that harmonize with the situation of the gaps on the new balance. Utilize 8-32 screws to mount the new weight to the apparatus. Take care to not dark the passageway gap for the 120-V supply wires with the weight.
Strip away 1/2 inch from the high contrast wires on the counterweight, if fundamental. Interface the highly contrasting wires from the house circuit link to the high contrast wires driving from the counterbalance, utilizing wire connectors. There ought to likewise be a red and blue arrangement of wires on the counterweight. Strip 1/2 inch of protection from these wires’ finishes, as required. Associate the red balance wire to both of the red wires driving from the light attachments. Associate every one of the blue wires driving from the attachments to one of the blue wires on the stabilizer.
Supplant the stabilizer lodging. Supplant the bulbs and any focal point, if present. Reestablish capacity to the circuit and check the activity of the new counterbalance by exchanging on the light.
Wiring a New Fixture
Mount the new installation to the roof or divider. You may need to expel the counterbalance lodging to get to the mounting openings. Ensure the installation is securely mounted, either to the roof joists, divider studs or with a code-endorsed electrical box intended to help a bright light.
Look at the new light installation: another T8 fluorescent light should as of now have the attachments and counterbalances wired in the best possible arrangement. Strip 1/2 inch of protection from the highly contrasting weight leads and from the dark and wire circuit wires, as required. Interface the high contrast leads from the stabilizer to the high contrast circuit wires, utilizing wire connectors.
Supplant the counterbalance lodging and any focal point, if present. Reestablish capacity to the circuit and watch that the light is working appropriately at the switch.
Things You Will Need
- Nut driver
- Wire connectors
- Wire strippers
- Needlenose pincers
- Cordless drill/driver
- Electrician’s gloves
- Non-contact voltage analyzer
- Electrical tape
- 8-32 tap and #29 bore
- Test your non-contact voltage analyzer with an affirmed live circuit before testing the circuit you are taking a shot at. Never expect that your analyzer is working appropriately.
- Ballast contrariness can cause untimely light disappointment or harmed gear. On the off chance that you are uncertain whether your T8 balance will work with your apparatus, attachments or the stockpile voltage, counsel a circuit tester.2 lamp t8 ballast wiring diagram
