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.
