How do you install 277 lights?

To install 277-volt lights, first, ensure you have the proper electrical knowledge and safety equipment. Turn off the power at the circuit breaker and use a voltage tester to confirm the power is off. Connect the light fixture's wires to the corresponding wires in the junction box, typically matching black (hot), white (neutral), and green or bare (ground). Finally, secure the fixture, restore power, and test the lights to ensure they function correctly.
