No Power Cords Inside The Wall

In plain and simple to understand words, it explains how running power cords through the walls is not a substitute or suitable instead of permanent wiring.

A new electric outlet installed directly behind the TV is what is required.

Power cables are not rated for in-wall use, can’t handle heat requirements, and installing them inside the wall is ILLEGAL.

Additionally, the insurance company will be happy to void covering a home should a fire result.

Safety Surpasses Monetary Gain

If any professional installation company advises it is fine to run power cords inside the wall, then those inexperienced professionals may not be aware of the (NEC) National Electric Code requirements or are more concerned about shortcuts than the personal safety of those who they call clients.
