I was wondering if any Macrumor users were electricians because I need some help. I am adding an outlet in an old home. The walls are solid block so it is surface mounted wiring. To keep the wire (14/2 Romex) it is in plastic raceway. Everything is going quite well until I hit the first obstacle. There is an old radiator. There is now way I can install the raceway/wiring behind this. Can the wire just sit exposed touching the rad or no? Thanks in advance!
