Replacing a Switch with a Dimmer Switch Hi i'm trying to wire in a dimmer switch. The hot source wire is connected to the common terminal on SW1. By code, the number of conductors allowed in a box are limited depending on box size and wire gauge. For more information about these circuits and troubleshooting tips check below. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. The traveler terminals will always be connected from switch to switch. If that is the case, you will have to pull your tools out and remove the switch to determine the problem.
If you do not size your dimmer properly the dimmer could overheat and cause internal damage. Newer specially designed fluorescent fixtures and dimmers are available which are are compatible and work well together. George, from Scranton, Pennsylvania I love this site for an office worker that does not know anything about electric wiring. If the meter shows continuity with the toggle in one direction and not the other, move the probe from that traveler terminal to the other one and test again. Below you will see some photos that I have selected to help you with your project. The maximum wattage should be clearly marked on the fixture. Calculate the total watts which will be controlled by your 3-way dimmer switch.

Wiring a 3 Way Dimmer Switch
This diagram shows the wiring arrangement for a 3 way switched outlet. Collin, from Grand Rapids, Michigan Thank you for answering my question. At the light, the hot source wire is spliced to the black wire running to the common terminal on SW2. The screw at the other end of the switch has either the Power or Switch Leg wire attached to it. Make sure the dimmer switch will be compatible with the lamps that are in the light fixture. Most dimmers are rated for watts of power consumption, so if you have several light fixtures which will be controlled by the 3-way dimmer switch you will need to count the number of fixtures, the number of lamps per fixture and the watts per lamp.

3 Way Switch Wiring Diagrams
If the connections are made with clamps instead of screws, tug firmly on the wires to be sure they are all still tight. There are 2 loads and 2 lines with in this switch. On this page are several wiring diagrams that can be used to map 3 way lighting circuits depending on the location of the source in relation to the switches and lights. The black and red wires running between the switches connect the travelers. Attach to the bonded ground wire s in the switch box. At the ceiling box, the wires for the fan and light are both spliced to the black wire running to SW2.
