Test Two Separate Wall Switches To Same Light

This is common with some older boxes when you have two single switches hooked up instead of one double switch.

Test two separate wall switches to same light.

An existing wall dimmer switch must be replaced with a single on off wall switch before installing a hunter fan to ensure consistent power flow from the switch to the fan. I know this can be done but i don t have a clue how to connect the switches to the fixture. You can wire two single pole light switches in the same gang box using a device that combines two separate single pole light switches into one device using the original single switch space. Connect black fan wire to the black ceiling wire.

To do this method the wire from your wall circuit to your light has to have 3 wires. Here two switches are wired in the same box to control two separate lights. Some gang boxes are in locations that do not allow the box to be expanded to add a separate light switch. One source is spliced to each switch with a pigtail to power the two lights.

One switch will be located outside on the porch and the other switch will be on the inside wall next to the door. Wiring two switches to one light fixture adds convenience to any room with two entryways. Also known as three way switching the job calls for a pair of special three way switches and an appropriate length of 14 3 conductor cable to join the switches together. Once you pull the 14 3 cable and the circuit power source wires from the switch boxes.

A 3 way circuit is a lighting circuit that allows one light fixture to be controlled by two wall switches in different locations. The source is at the switch box and a 2 wire cable is run to each light. This method allows you to operate the fan and light power separately. A single wall switch controls the power to the fan and light together whereas a dual wall switch has two separate switches one for the fan and the other for the light.

It isn t unusual to wire two or more light and switch combinations from the same power source in fact it s common practice. Stairwells hallways and large rooms with multiple access are all candidates for 3 way circuits. How to wire two separate switches lights using the same power source. There are also four way five way and a gazillion way circuits.

After making sure the power is off you strip the black wire in the two conductor cable which also has a ground wire and make a pigtail with two 6 inch lengths of black wire salvaged from a spare piece of cable of the same wire gauge. Your power supply line the black wire should be feeding both switches and those switches power the fan black or the light blue. It may in some cases even return to the wall from the second switch. A hot wire red or black comes out of the wall and into one switch then out of that switch and into the other one.
