- Verify that electrical equipment is not located in a hazardous environment, such as a damp/wet location, low light or dusty conditions, elevated or hard to access locations, or where it is exposed to extreme temperatures or flammable gas or vapors
- Make sure overcurrent and safety devices, such as fuses, circuit breakers and ground fault circuit interrupters (GFCI) have not been damaged and are working correctly
- Inspect the power cord and plug to ensure there are no defects, such as cuts that expose wiring. Make sure the cord is large enough to handle the load
- Make sure there is sufficient space around breaker panels, disconnects and similar equipment to allow for operation and maintenance
- De-energize electrical equipment before testing or repairing in accordance with Lockout/Tagout standards
- Always use appropriate tools and safety equipment, such as insulated equipment and personal protective equipment (PPE) when working on electrical equipment
- Verify sources of back feed from generators or alternate energy sources.
