To wire the combo switch you will need to determine the hot line in the box. Once you have done that you will hook the hot wires to the gold screws on the switch or the black wires on the pictures below. The red wire will go to the switch leg white wire with tape on the second picture. Then the the white wires you will attach to the neutral screw on the first picture. That is how you will wire this switch.

A combo switch/receptacle is handy when you need both, but you only have one outlet box available. These devices come with a removable connector between the two hot terminals. When intact and wired to one hot source wire, this device can be used to turn a light off and on while the receptacle will be constantly hot.

This diagram shows the first wiring option for this device. Here the hot source comes in to the hot terminal on the receptacle and 14/2 cable runs from the device box to a light fixture. The source neutral is spliced to the receptacle and to the white cable wire going to the fixture. The output side of the switch is connected to the black cable wire running to the hot terminal on the fixture.

In this drawing below the connection tab between the hot terminals on the device is broken off allowing for wiring two separate source, one for the light and one for the receptacle. With this arrangement the switch controls a light and the receptacle outlet is constantly hot.
Source 1 comes in at the light fixture and a 14/2 loop runs to the switch half on the device. The hot from the source is spliced to the black wire on the loop and the source neutral connects directly to the fixture. At the combo device the black wire from the loop is connected to the input and the white wire is connected to the output. The cable ground wire is not used and should be taped and folded to the back of the boxes, out of the way.
Source 2 comes in at the device box where the hot and neutral wires are connected to the corresponding terminals on the receptacle half of the device.


Or you can go to the link below. At the bottom will tell you how to wire.

    The red wire is the wire that is going to the Light. So you will pit the red wire on the left of the switch like in picture 1 top of the white wire.

    The black wires will go on the right side of the plug/switch like on picture 1

Replacing a switch outlet combination with a switch GFCI outlet combination and there is only one cable in the box (14/3)

If it worked before, it should be a wire to wire replacement. You are replacing a regular switch/outlet with another switch/outlet which just happens to be a GFI outlet.
Wire the old switch wires to the new switch and the old outlet wires to the new outlet.
Cut the breaker/s off first !!

From your switch box to your fan run a 14/3 wire. Take the incoming 14/2 white wire,and connect to white of the 14/3 wire to fan lite combo ,and hook both white wires from fan and lite. Hook the fan black wire to the black wire from the 14/3 Hook the black wire from the fan to the red wire from the 14/3. Then go back to the switches, and add a black and red pigtail about 4"long to the black wire from the 14/2, now connect the red wire to one side of switch, and the other red wire from the 14/3 to the other side of switch. Do the same to the black wire on the other switch.

Open following link for wiring diagram with written instructions.
Some of your wiring does not sound up to code.

1) Two differences between regular switch and cooper 277
-Different color screws: Regular switch has two brass screws, and either wire can connect to either screw. Cooper 277 has dark, brass, silver screws, and hot wire connects to dark screw, and wire to light connects to brass screw.
-Cooper needs neutral wire connected to silver screw, to power the indicator light.

2) Some of the wiring in your box does not sound up to code.
Bare ground wire should not be connected to black and white wires.
Electrician should check this out.
Probably the ground wire is being used as a Neutral. Bare ground wires and white neutral wires both connect to neutral busbar at main breaker box.

The red wire is probably the switched leg to the light.. You can verify this by turning the power to the circuit OFF at the circuit breaker, then pull the switch from the box. Post back if you need more assistance.

You are replacing single pole light switch?
Single pole switch has 3 wires: black and red and bare copper

New device has 4 different colored screws: green, dark, brass, silver
Bare copper goes to green screw.
Black wire goes to dark screw
Red wire to brass screw
Nothing on silver screw for a moment. Test circuit and make sure light turns on-off.
If lights works, then good so far.

Now let look at silver screw. Neutral wire has to connect to silver screw.
In back of your electrical box are white wires twisted together and covered with wire nut.
These are neutral wires.
You must connect another short piece of insulated wire to these neutral wires and run that wire to silver screw.
The neutral wire will complete circuit to receptacle.
If you do not have neutral wire, then receptacle will not work in that box without additional wiring.

Hook up neutral wire to silver screw.
Now turn on power and click switch again.
If circuit breaker trips, then reverse your red and black wires.
Otherwise this should be correct wiring.

Utilitech Wall Timer #0192773 does not switch landscape lights on? Replaced Intermatic that had 3 wires. Black to Black, blue to black and red was capped. Utilitech came with 4 wires - black, white,...

Old timer: Intermatic EJ500 & ST01C timers have a battery. Battery operates the clock motor. Red wire is for 3-way circuit [a hallway with 2 switches is a 3-way circuit].

Utilitec timer, clock runs on 120Volt circuit instead of battery. So clock has to have power.

How to connect wires:
Black timer wire connects to hot wire from breaker box.
Red (or blue) timer wire goes to landscape lights.
White timer wire connects to white neutral wire [or if no neutral is available, connect to bare ground wire].
Green timer wire goes to bare ground wire.

How to find black hot wire and white neutral wire inside box
: Disconnect and separate wires so you can test. Use ordinary tester. Power is on. There is only 1 black hot wire inside each electrical box. Test each black wire to bare ground until tester light comes on > that identifies the black hot wire. Next, test black hot wire to white wires until tester light comes on > that is the neutral wire. Exception: This test does not necessarily work with 3-way switches since they reverse each time switch is thrown.
