I removed and replaced 4 receptacles. 2 in the master bedroom, 1 behind the couch in the living room, and 1 in the dinning room. I spliced all the appropriate wires together and pig tailed off the splice hooking the single wire around the new device screw and clamp and tightened down the screw to ensure the best and safest possible connection throughout the circuit. I replaced a 3 way switch in the basement for the stairwell light. I removed and replaced the 2 master bathroom lights with customer supplied lights I removed a surface mounted light in basement and installed a 6 inch led wafer recess lights
