My new home has a built in, corner, entertainment center. It has electrical, cable, and phone connections. On the other side of the wall is the location of where I will hang my TV in a bedroom.
Is it considered acceptable/code to install some type of thru the wall "hole/box" to run electrical cord and cable TV coaxial from wall hung bedroom TV, thru the wall, and plug all in at entertainment center?
I know how to do so. That part is a no brainer but acceptable/code is the question.
You can run a coaxial line through the wall. The power cannot be run that way. You must install a new box with a new receptacle in the bedroom. Depending on which code cycle you're on, the receptacle may be required to be AFCI protected.
