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

When removing insulation from wire, do NOT score or put cuts on surface of copper wire. Doing so increases resistances on wire and creates weak point.

Timer caught fire
install water heater timer Project overview: Requires Neutral
Use any programmable timer, zwave or wifi device that is rated for resistive load.
Use Hot and Neutral from nearby 120 volt outlet to power device.
Rule of thumb: Outlet box will always have Hot and Neutral, Switch box will always have Hot but not always Neutral, Ceiling box with light will always have Neutral but only has Hot when light is on.

How to set up wemo on your wifi network
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.
Insdulation under screw plate

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  
Push on wire connectors
Use push-on wire connectors
3 wires/ or different gauge wires
Join wires with wire connector or push-on connector

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
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
