  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. Buy: Non-metallic flexible conduit Power whip Armored cable Southwire armored cable cutter Pull boxes |
 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. Buy tools: KLEIN TOOLS Wire strippers at Amazon Electric Wire Stripping Machine Linesman pliers Utility knife at Amazon |
 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 |
 GFCI circuit breaker A GFCI circuit breaker will protect all boxes on circuit. Circuit must be grounded. Ground wire must be continuous and connected to each piece of equipment. White wire on circuit breaker must be connected to Neutral busbar inside the breaker panel. Buy GFCI circuit breakers |

Override switch for timers, wifi, zwave: This plan draws hot and neutral from a small transformer Use regular 15 amp 3-way wall switch from hardware. Transformer rated 23 watts. Contactor consumes 27 watt for brief moment during inrush (start-up) and 7 watts during operation. Can't find power consumption for wifi switch... can't be zero ... seems the information highway is stalled by commerce. Transformers are very reliable with no moving parts, however the WeMo, wifi, zwave and digital timers are not as reliable, and override might be needed both for convenience and testing. To bypass the contactor the altogether requires 30 amp DPDT switch Buy: 3-way switch Transformer/ 25 watt output/ 2.8" diameter x 1.25 thick Transformer option 2 Contactor with 120 volt coil 7 watt power consumption Programmable timer Countdown timer Zwave switch Wifi switch |

 What is a contactor? What is a contactor? Contactor is a switch. It is rated for high amp loads. High amp causes heat. Heat will damage regular electrical parts. Timers and wall switches can be damaged by high amperage. Each switch and timer has amp rating. Contactors are rated for more amps than ordinary wall switch or timer. The electrical circuit lasts longer when a contactor is used because contact points on a contactor are designed to switch high amp loads without melting or being damaged by heat. The electromagnetic coil can be switched on-off using ordinary wall switch or timer. When voltage is applied to coil, then contact points close, and heavy amp circuit turns on. This lets you control heavy amp loads using ordinary wall switch or timer.

WeMo
controller kit in plastic box Comes with WeMo and contactor plus 240V-to-120V transformer Assembly required. Install ground wire as shown. Water heater cable does not have Neutral. WeMo requires Neutral. If you connect Neutral to ground, it will work. But in event of nearby lightning strike, or other ground disturbance, the surge of power is directed down the ground wire, and MIGHT enter the WeMo and cause fire. Ground wires offer path of least resistance for surge events because all grounds are wired directly together without passing through devices like switch etc. Installing VPT230 will reduce magnetic field interference with WeMo RECOMMEND pvc or plastic box so wi-fi signal is not blocked Buy: Transformer Transformer option 2 Cantex 6x6x4 plastic box WeMo switch Contactor with 120 volt coil Panel mount fuse holders at Amazon  Buy: Step drill bit for drilling into PVC box Resource: Set up manual for transformer VPT230 transformer manual WeMo controller kit manual |

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.
