Our electrical panel box is installed on the exterior brick veneer wall of our house. I am having our electrician add an extra 20 amp branch circuit to the panel to feed 3 new receptacles in the kitchen area, the first of which will be GFCI-AFI protected, which in turn will protect the other two downstream.
The least labor intensive way to route the new cable from the panel box into the unfinished attic is to run it directly from the panel box into the soffit above the box (a distance of 11 inches), then into the unfinished attic. I realize Romex cannot be placed in conduit, even for this short 11 inch exposed distance. Therefore, I am considering using 12 AWG THWN for the connections inside the box, then run the THWN via conduit (either PVC or EMT) into the attic. Once inside the attic, the THWN and Romex will be spliced inside a junction box, then the Romex will be run across the rafters to the new outlets.
I have two questions about this:
1. Is using THWN for the connections inside the panel box, then splicing with Romex once inside the attic space, an accepted and code approved practice in this unique type of situation, where the panel box is located outside. If not, then what are possible options in cases like this?
2. If splicing is acceptable, would the splice itself have any negative effect on the proper functioning of the GFCI-AFI that will be installed on this circuit? If the splicing degrades the circuit in any way, shape, or form, then I presume nuisance tripping would be a regular occurance.
Any professional input on these two questions is appreciated so I can plan ahead.
