I have an old house, complete with plaster+wood lathe walls. The master bedroom upstairs is fed from an overloaded old circuit that I want to replace with a new branch circuit.
I see two options; NM and amored cable. The NM option is use all NM cable for feeds to outlets, and at every stud, remove the plaster, snake the cable past the stud, and put a nail plate in. This would obviously require alot of patch work and painting. The BX option is to use all armored cable by removing the baseboard trim, securing the cable behind it and go up to each recept. from there.
Because I need to get past a few door frames, using all armored cable seems to make sense. I have seen this trick in several DIY books.
Is there any issue with this approach?
