There are a few methods you can use to mount luminaires to an outlet box with an offset bar hanger:
1. Using the Bar Hanger Directly:
* For Lightweight Fixtures: If the luminaire is light enough, you can directly attach it to the offset bar hanger using screws, bolts, or other suitable fasteners.
* Check Compatibility: Ensure the bar hanger is compatible with the fixture's mounting holes or brackets.
* Proper Installation: Make sure the bar hanger is securely attached to the outlet box and the luminaire is firmly mounted to the bar hanger.
2. Using a Mounting Bracket:
* For Heavier Fixtures: If the luminaire is heavy, it's best to use a mounting bracket attached to the bar hanger.
* Choose the Right Bracket: Select a bracket specifically designed for offset bar hangers and compatible with the fixture's mounting configuration.
* Secure Installation: Mount the bracket to the bar hanger with appropriate fasteners, then secure the fixture to the bracket.
3. Using an Adaptor Plate:
* For Specialized Fixtures: Some fixtures may require a special adaptor plate to mount to an offset bar hanger.
* Adaptor Plate Compatibility: Make sure the adaptor plate is compatible with both the bar hanger and the fixture.
* Proper Fit: The adaptor plate should securely fit onto the bar hanger and provide a stable platform for the fixture.
Important Considerations:
* Weight Limits: Check the weight limits of the offset bar hanger, the mounting bracket, and the outlet box to ensure they can support the fixture's weight.
* Electrical Connections: Ensure all electrical connections are properly made and secured before installing the luminaire.
* Code Compliance: Follow all relevant building codes and electrical safety regulations during installation.
* Safety Precautions: Always work with electricity with caution. Disconnect power before working on any electrical wiring or fixtures.
Example of a Common Method:
1. Attach the Bracket: Secure a mounting bracket (specifically designed for offset bar hangers) to the bar hanger using appropriate screws or bolts.
2. Install the Fixture: Mount the luminaire to the bracket using the provided hardware.
3. Electrical Connections: Make sure all electrical connections are properly made according to the fixture's instructions.
4. Secure the Fixture: Tighten all mounting screws or bolts to ensure the fixture is securely mounted to the bracket and the bar hanger.
Choosing the right method for mounting your luminaire depends on the specific fixture and the available mounting options. Always consult the fixture's instructions and seek advice from a qualified electrician if you have any doubts.
