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.

GFCI circuit breakers
armored cable
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.

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

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.

Cooper pilot light switch

Cooper pilot switch                    Look at screw color
Pilot light turns ON when switch turns ON.
Cooper and Leviton pilot switches have same screws but screws are located on mirror opposite sides of device. Except ground screw is different on each.
Look at screw color. Silver for Neutral. Green for ground.
Note which screws are joined by break-away fin.
Hot from breaker box connects to screws with break-away fin.

See testing photographs 1 2
-Read about 120Volt circuit

Each 120volt electric box has only 1 Hot wire.
Take photo of wiring, separate wires for testing, and then test each wire to bare ground wire, and tester will light up on 120V Hot.
If you are replacing ordinary switch that has 2 wires, one of the wires is Hot and other wire is Load. Remove switch, turn power ON, tape tester leads to wood sticks, and test each wire to bare ground wire. Tester lights up on Hot.
What is neutral wire: Neutral wires are the white wires that are twisted together and covered with wire connector and pushed to back of electric box.
If box does not have neutral wires, the pilot will not work.

Black Hot wire from breaker box connects to darks screws located on same side as break-away fin.


Load wire going to light connects to brass screw opposite the switch.
Bare ground wire connects to green screw
White neutral wire connects to silver screw opposite the pilot light.

Unlikely that pilot is ON only when light is ON
Unknown if pilot is ON only when switch has power

Single outlet GFCI. Pilot light is ON when device has power.
When GFCI trips, then pilot is OFF. Wiring is identical to ordinary GFCI outlet, and can replace any ordinary GFCI device
Difference: pilot light light switches shown above, the pilot is ON only when light switch is ON.

If you are replacing ordinary switch that has 2 wires, one of the wires is Hot and other is Load. Remove switch, turn power ON, tape tester leads to wood sticks, and test each wire to bare ground wire. Tester lights up on Hot.

Outlet works all the time, and switch controls separate light, and does not control outlet.

1) Polarized outlet has a wide blade and narrow blade.
Black Hot wire from breaker box connects to screws that are on same side as narrow blade.
Notice also that screws on Hot side of device have a break-away fin. If fin is removed, then add a wire that connects both screws.
Each 120volt electric box has only 1 Hot wire that tests 120V to ground wire.

Load wire going to light connects to brass screw opposite the switch.
White neutral wire connects to silver screw opposite the outlet. Neutral wires are the white wires that are twisted together and covered with wire connector and pushed to back of electric box

Leviton 7299 can not be wired this way
Other models and brands can be wired this way
How to wire switch outlet combo so switch controls outlet
If your switch does not have 2 screws on Hot side, then this wiring is not possible
Hot side has the narrow outlet blade.

Review instructions above for basic wiring
1) Use screwdriver or pliers to remove break-away fin between Hot side screws.
If Hot side does not have break-away fin, then wiring is not possible.
2) Add a jumper wire between brass load screw and outlet screw as shown in diagram

How to wire TM8111 switch

Residential wall switches are generally rated 120V or 120-277 volt AC.
Look for volt and amp rating embossed on the electrical device. Do not exceed rating.
120 volt switch can only be used for 120V only.
120-277 volt switch can be used for 120-208-240-277 volt
Electrical code allows 15 Amp switch, combo switch, pilot light switch, GFCI etc to be used on 15 or 20 amp breaker.
Electrical code allows 20 amp switch etc on 20 amp breaker only ... but not on 15 amp breaker.

20-30-40 amp switches can be used for lower amp loads but breaker and wire size MUST match load rating.
All 4-screw 4-way switches are rated 120-277 volt.
All 4-screw double-pole switches are rated 240 volt ... for use on 120-208-240 volt, but not 277 volt.
For higher voltages, such as 480-347-600 volt etc, use a motor control switch.
For 3-phase applications, use a switch or timer to activate contactor.
