| Use only 600 volt wire. Lamp cord, extension cords are not rated 600 volt. Use copper wire only. Aluminum wire is fire risk and should be avoided or installed by professional. 30 amp breaker use 10 gauge / 120-240 volt 30 amp outlet can be installed on 30 amp breaker only/ use 10 gauge wire ... cannot be connected to 15-20-40 amp breaker.

 Multimeters Voltage is tested across two separate wires. Ohms or resistance is tested across both ends of same wire. Amperage is tested along one or two points on same wire. Buy: Analog multimeter Multimeters at Amazon Klein multimeter Electric testers at Amazon Clampmeter for testing amp flow on line |
 Electrical tools must be insulated. Always best to disconnect power, but insulation failure, lack of proper grounding, grounded neutral, lack of GFCI, out-of-code wiring, generator operating without transfer switch, and other problems still pose a risk to anyone working on electric power ... even when breaker is off.

 Protect wiring from damage Use nipper instead of pliers or screwdriver for removing staples (and nails). Do not damage cable or wires inside cable. -Code says: Cable SHALL BE secured without damage to the outer covering. NEC sec. 336-15 Buy End cutting nippers at Amazon |
 Electrically insulated tools When removing insulation from wire, do NOT score or put cuts on surface of copper wire. Doing so increases resistance and heat on wire and creates possible weak point.

 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 |

T-105 timer: 2-speed 120 Volt pumpTimer acts as a high-low switch for continuous-running 2-speed pumps.T105 timer does not turn pump off. Use P1353 for 2-speed pumps that turn off >Or use 2 timers, and wire first timer before T106. Typically, a T101 timer would be integrated into circuit for that task.

T-105 timer 120 volt/ Toggle between 2 different loadsT105 timer has NO NC terminalsWhen timer is OFF, then NC Load 2 is ON, and NO Load 1 is OFF When timer is ON, the reverse happens, and Load 2 is OFF, and Load 1 is ON Use this configuration for 2-speed 120Volt pool pump that runs continuously. Use NO NC connections to change between High and Low speed For 240Volt application,.buy T106 timer. Or replace WG1570 clock motor with WG1573 Buy: WG1573 240 volt clock motor |

T-105 timer: Single-pole Normally ClosedThis lets you operate any 120 volt load using T105 timer.T105 acts like ordinary ON-OFF timer for any 120 volt load up to 40 amps. Normally Closed means the circuit is turned ON, and power is available to run Load. When timer activates, the circuit is turned OFF Move clock motor wires from A-3 to A-1 |

| Wiring Tips | |
 |
Keep wires straight Use solid copper wire If wiring terminal or end of wire are covered with green, use emery board to clean terminal and sandpaper to clean wire. |
  Larger image |
Both wires MUST be same gauge Straighten each wire If wire is corroded or overheated, clean the end with sandpaper and wipe with cloth. If wire has been melted, cut back and reattach, or replace wire. Tighten screw very tight against copper wire |
|
 Use wire connector  Use push-on wire connectors |
3 wires/
or different gauge wires Join wires with wire connector or push-on connector Run jumper to screw terminal. Buy: Red 3P connector (shown) for 10-14 gauge wire Lever connectors for stranded wire |
|
 |
Fire safety/ Do not put stranded
wire under screw plate Do not install stranded wire under screw. Problem1: picture shows 2 different gauge wires under screw plate Problem2: Stranded wire will expand and contract and come loose under screw plate, even if it is the only wire under the screw plate Attach stranded wire and solid wire with wire connector, and run solid copper jumper wire to screw terminal Take photo of wires before starting.

10 gauge or 12 gauge? Compare your wire with short pieces of 10 and 12 gauge wire from local box store 10 gauge for 30 amp breaker. 10 gauge wire can have black-white and sometimes black-red 12 gauge for 20 amp breaker 12 gauge will have black and white wires Buy: Southwire romex cable Resources: Match color code and amp rating for wire Basic house wiring |

Add black tape when White wire
carries voltage (applies to 208 and 240V circuits) With 120 and 277 Volt circuits, White wire is Neutral, and Black is Hot With 208 and 240 circuits, both wires are Hot, and both wires carry voltage Black tape on White wire identifies wire is Hot and not Neutral |
