Electrical Question: How can I wire a dimmer switch for light fixtures?

• I am wiring a new dimmer switch for a pair of pendant lights for above a snack bar.The dimmer switch is going next to an existing dimmer switch controlling a fan and fan lite in the same room.
• I was going to use the power source from that circuit to power the new lights.
• There is only a white and black in the dimmer switch box.
• I am thinking the power source for the fan is coming from the other side of the fan.
• How can I wire the new dimmer switch for the pendant lights using only the two wires in the existing box?

Thanks

How to make the Electrical Wire Connections When Wiring a Dimmer Switch

• Dimmer Switch for Additional Light Fixtures
  • The wiring for the new pendant light fixtures requires a power source with a neutral wire.
• Electrical Power for the Dimmer Switch
  • From what you have described the existing dimmer switch only has an incoming power feed and the switched leg back up the the fan and fan light.
• Locating Power for a New Dimmer Switch
  • A power source must be either brought to the pendant lights or to the switch box location so the neutral, hot and ground wire will be available for the pendant lights to operate.
