Terminals:
Crimp terminals onto stranded wire Solder terminals onto solid wire Buy: Terminal kits Terminal kit at Amazon Blue terminals for 16-14 gauge wire at Amazon Yellow 12-10 gauge female terminal 16 pcs |
 Larger image Terminals used on 2-pole 40 amp contactor With removable dust cover on top. Select correct voltage needed to control coil. Water heaters typically use 240 volt coil, HVAC replacement is 24 volt coil. Typical 2-pole contactors are rated with 24, 120, 208-240 volt coils. Three pole contactors for 3-phase are available in more coil voltages not found in residential applications such as 277, 480 etc. Using the wrong coil voltage will cause problems. Selecting a contactor rated for more amps is better, so using 240 volt 40 amp contactor for 240 volt 30 amp water heater is fine.

Terminals
work best on stranded wire Tip for solid wire: use hammer to flatten solid wire a bit so terminal grips better |
 Never use solder for 120-240
volt residential wiringWhy not? Because residential 120-240 volt carries high heat. The heat will melt solder, causing soldered connection to deteriorate or come loose. Solder can be used for structural wiring such as doorbell, communication lines etc Solder is Not necessary when using stranded wire. Best to use stranded wire and connect stranded and solid with wire connector Instructions how to solder: Put solder iron or gun tip where wire terminates. Wait until hot. Keep tip in place on wire until hot. Touch solder to copper wire. Solder melts. Withdraw solder. Withdraw solder point.

 Use crimp teeth to crush terminal onto wire Buy: Terminal kit at Amazon with crimp tool Electrical terminals at Amazon |
 |
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. |

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: Push on wire connectors at Amazon Red 3P connector (shown) for 10-14 gauge wire Connector assortment Resource: How to select and install wire connector |

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 .

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 |

Multimeter Test for breaks in wire/ Test for voltage Most appliance require 80% rated voltage to function correctly Buy Analog multimeter Multimeters at Amazon Klein multimeter Electric testers at Amazon Clampmeter for testing amp flow on line Resource: How to test and replace element How to test thermocouple Element tests for 120 volts How to test wire |  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.

 Use outlet tester to check for correct wiring on any 120 volt straight-blade outlet. Buy: Klein testers Outlet tester Circuit breaker finder Electric usage monitor |  Non-contact voltage tester Test for power without touching connectors NEVER assume power is OFF Buy: Non-contact voltage tester Amazon Electric testers at Amazon Resource: How to test electric power is off |
 Weather resistant plastic box for outdoor extension cord connections, Christmas lights, outdoor power strip etc . Not for connecting wires with wire nutsŪ, or in-wall wiring, but can be used indoors to organize extension cords, power strips etc. Weather resistant is not weatherproof or watertight. Use enclosures rated IP65 and IP67 for waterproof. Extension cords cannot be used for permanent wiring.

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 |
