 Use only solid copper 600 volt residential wire Buy: Southwire 10-3 wire |
 |
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. |
 Use
correct wire and breakerUse only 600 volt solid copper wire Match amp load with wire size and breaker All 3 ... amps ... wire size ... and breaker ... must be matched Breakers are rated by amps. Each breaker is
rated for 80% safe maximum
So 30 amp breaker has safe max 30 x .80 = 24 amps Each load (light, motor, appliance etc) has a watt and volt rating. Figure amps for load: If load is 4500 watt
water heater, that is connected to 240 volt ...
then divide 4500 watts by 240 volts = 18.75 amps 18.75 amps exceeds safe max for 20 amp breaker (16 amps) Use 30 amp breaker Each breaker has a corresponding wire size 20 amp breaker: use
12 gauge wire
30 amp breaker: use 10 gauge wire Resources: Wire and breaker sizes Figure volts amps watts for water heater |

  12 Ga |
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 . Resources: Match color code and amp rating for wire Basic house wiring |
 |
Basic electric safety can include: Adding black tape when White wire carries voltage (applies to 208 and 240V circuits) Why? Black tape on
White wire identifies wire is Hot and not Neutral
 With
120 and 277 Volt
circuits, White wire is Neutral, and Black is HotWith 208 and 240 circuits, both wires are Hot, and both wires carry voltage |

  Copper ground wire. Every device, load, metal enclosure etc must be grounded. Ground wire must be continuous throughout installation, never switched on-off, never used as a Neutral wire. Generally ... use same size as other wire in circuit Buy: 12 gauge copper ground wire Ground wire Green ground wire Ground pigtails Ground rods/ ground clamps at Amazon |
 Non metallic flexible cables must carry ground wire, but do not have hazard of short circuit causing injury from shock. Armored steel cable can be used as a grounded connection, and will protect wires from damage. Metal can be energized from an insulation failure. All conduit ...metal, plastic ... flexible and rigid ... must be attached to structure, and attached to enclosures, boxes. Movement, damage and deterioration are major cause of electrical failure.

 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.
