My existing wiring has 2 black and 2 white and a ground. One pair is obviously source. The 2nd pair passes to the next outlet.
The current outlet has 4 screws: black on one side and white on the other.
Now I need an outlet with USB ports, so I selected the Leviton t5633-w because of its high USB amperage.
It only has 1 set of screws.
Can I add a short piece say 4-6 inches to the black and the white so I can connect it to the single set of screws?
Therefore there would be 3 black wires wire nutted together, and 3 white.
Physically, it's clear I can do this. However, what does the US National Electrical Code say?
