• Identifying hot and neutral wires
• Testing wires with a non-contact voltage tester
• Creating pigtails with Wago 221 lever nuts

What it concludes

• Commercial grade duplex receptacles can handle load from other branches, but professionals prefer making pigtails for hot and neutral wires to make installation cleaner and easier.
• Speed wiring and clockwise J-hooks on 14 AWG wire for residential receptacles are not recommended due to increased likelihood of failure.
• GFCI outlets require knowing the incoming power line to correctly protect downstream branches.
• Integrated USB port receptacles with a single terminal require pigtailing the hot and neutral wires.
