gregmac's terrific, detailed replies here prompt a question for me. I have a switch mid-circuit that will control half of the next outlet downstream. There is one more outlet after that one, and it's the terminus of the circuit. After I've added the 3-wire romex between the switch and the second-to-last outlet, can I go back to 2-wire from that outlet to the last one?
Thanks in advance for any and all help!
