I have a single pole switch on my wall and I am looking to run a wire to a lamp on an opposite wall. Because these are finished walls, I am unable to run new wiring through the wall. I am wondering if it is possible to run some flex from my switch to an existing receptacle and then run the switched wire from the receptacle out to some surface raceway and then along the raceway to the other wall and up to the light. So, my question is: Is it up to code to connect a receptacle that is in the wall to surface runway? If it is, how would I do this so that it is code compliant?

I installed new HOMELINE breaker. I hooked the plastic end first and pushed the breaker onto the busbar. How hard or how much force should it get to clamp down on the bus? Like when it snaps into place is that good enough or are you supposed to forcefully push down on it? I assume they just snap and don't have a pressure or torque value like the screw?
