Safety
when testing wires: Never touch wet or previously flooded appliance. Never stand on wet surface when working on electric. Never stand on bare soil, put down dry boards. Tape tester leads to wood sticks to keep hands away from power. Use non-contact voltage tester before touching wires. Never touch or lean into any made of metal. Remove metal objects from pockets. Do not use oxygen or fuel accelerants in same room as electrical repairs Resource: Basic house wiring |

Single-phase 120-240 volt
twist-lock outlet or connector is
marked X-Y-W-G or X-Y-G 120V and 240V requires two wires to complete circuit, and ground wire for safety. 120V requires 1 hot and 1 neutral. 240V requires 2 hots. Neutral is not needed for 240volt electric circuit, but is sometimes included on electrical device, depending on end-user application. Resources: See inside main box Figure volts amps watts Select correct wire and breaker Electrical formulas Z is used for 3-phase and not shown here. Commercial 3-phase outlet is marked X-Y-Z-G or X-Y-Z-W-G Resource: How to wire 3-phase |

| 125-240 volt 20-30 amp Twist Lock | |
  You can use 30 amp twist lock for 15 or 20 amp circuit. But you cannot use 20 amp for 30 amp circuit. You can use a 4-wire twist-lock device with 3-wire installation. But you can not use 3-wire twist lock with 4-wire installation. You should never use 120 volt device for 240 volt circuit.... buy the correct rating for load. Why Leviton: quality materials (ie brass terminal screws) and durability over time. Why 125-250 volt ratings instead of 120-240 volt: incoming service voltage can vary at each location. |
