- Lock out and tag out the electrical circuit yourself. Never rely on others to do this for you.
- BEFORE performing electrical work:
- Open the circuit breaker or load break switch away from the enclosure to de-energize the incoming power cables or conductors.
- Open the visual disconnect away from the enclosure to confirm that the incoming power cables or conductors have been de-energized.
- Lock out and tag out the visual disconnect.
- Ground the de-energized phase conductors.
- Wear properly rated and well maintained electrical gloves when troubleshooting or testing energized circuits. After the electrical problem has been found, follow the proper steps before performing electrical work.
- Use properly rated electrical meters and non-contact voltage testers to ensure electrical circuits have been de-energized.
- Only use qualified, trained workers. Ensure electrical work is performed by a qualified electrician or someone trained to do electrical work under a qualified electrician’s direct supervision.
- Identify circuits and circuit breakers. Properly identify all electrical circuits and circuit breakers before troubleshooting or performing electrical work.
