Electrical Wiring for Light Fixtures
Electrical Question: I wired some new lights and they do not work right, what did I do wrong?

• I installed three florescent lights in my five bedroom work room. I used 3-wire with black-white and red. One switch is suppose to control two lights, and one the other.
• I used the black and white to feed the two outside lights. The red and white to feed the center light. When I turn on the outside light, I get a soft light from the center one.
• I turn on the center same with the outside. Do these types of lights have some sort of floating current. I’m really sorry I didn’t go with the recessed lighting.

I hope this makes sense to you.
Thank you.

Thanks for your electrical question John.

### Simple Mistakes When Wiring and How to Avoid Them

A very common mistake that homeowners make when installing electrical wiring is that they make the wiring connections in a series instead of parallel. When wiring in series the electrical power is routed through each light fixture or device which then creates resistance on the circuit. Parallel wiring allows the full power of the circuit to be delivered to each light fixture or device.

SOLUTION
Map out the circuit wiring and examine all the wiring connections to switches and light fixtures and rewire series wiring to be parallel connections.

IMPORTANT
Incorrect series wiring can damage devices because they are not getting full power which may overheat the device and it’s components.
