What is the proper way to daisy chain duplex outlets?
Based on what I have read here, I am under the impression it is not allowed by code to connect the incoming wires from the previous outlet (or panel) to one screw terminal, and then connect the outgoing wire to the other screw terminal. I have been led to believe that the wires must be wire-nutted to a third pigtail wire which is connected to the one of the screw terminals.
I ask because the electrician doing the wiring for my basement remodeling did the latter. Is this a code violation? Is this unsafe in any manner?
