Looking at a set of three way switches standing inside a jobsite environment can be intimidating. But looks can be deceiving, even on paper. Try practicing wiring to help. Electrical Equipment is switched on/off daily using many types of switching devices. Switch wiring should be standard for trained eye. Always use the process of elimination in a safe environment, preferably away from your home since sparks can fly.
Wire nuts for residential use are not intended to contain sparks, only to join two wires. This type of wire termination can also produce sparks while making the termination if voltage is applied.
Before beginning, If you are in the middle of connecting a three-way circuit and you have all the wire pulled, it should not take long. If you are starting from scratch and have nothing installed, please let me know upfront before we get into conversation.
