I removed all devices in home and replaced them with tamper resistant receptacles, new switches, dimmers, stacker switches and new gfcis in locations they are required by code. I spliced all appropriate wires together then pig tailed off the splices and took the single wire and wrapped it around the device screw then tightened the screw. This ensures the best and safest possible connection throughout the circuit. I ran a dedicated 20 amp circuit from the garage to the main electrical panel. I ran the UF wire outside through the rafters then to the side of the home where i installed 3/4 inch pvc pipe down the side of the home to protect the wire then i ran it into the home where the electrical panel is. I installed a tamper resistant gfci in the garage and a 20 amp circuit breaker in the panel I installed 2 ground rods outside then ran a #4 ground to both of them then into the home into the main electrical panel I ran a #4 ground wire from the main electrical panel to the entrance o
