Question: I wrote a proposal and would like some input. Basically I added a new part to 400.7 Uses PermittedChange or Addition400.7(A)(11) Where used to power an inlet (flanged receptacle) and outlet where the wiring thru the premise is a chapter 3 wiring method.Substantiation:It appears that some areas of the country will not allow these products based on 400.8(1). I do not see this as a substitute for permanent wiring as the wiring in the walls is approved chapter 3 methods.This will clarify products used for TV’s and their components that are listed for this use as being NEC approved. Specifically there are products that provide a flanged receptacle inlet that is used to power a flat screen TV from a remote location. The wiring thru the walls would not be connected to the wiring system of the house but would be energized only when a rubber cord similar to a computer monitor cord is used to energize a listed flanged receptacle from the TV’s remote units. This inlet outlet is connected to a wiring method approved by chapter 3. At the other end is a standard receptacle in which the flat screen is plugged into. This apparently allows the TV’s to be on the same circuit and avoid ground loops that can cause problems with TV’s.These listed products are listed with two sets of cords and both inlet and outlet receptacles.. Without trying to endorse a product here is one of many products out there.I then posted the powerbridge inlet and outlet-- should I delete the product name? I thought if they wanted to learn more the info was there.
Revised Proposal
Change or Addition
400.7(A)(11) Where used to power an inlet (flanged receptacle) and outlet, provided that: The wiring between the inlet and outlet is a Chapter 3 wiring method. The inlet and outlet are part of a listed assembly.
Substantiation
Rationale
This change clarifies that the use of listed assemblies for powering televisions and their components is permitted under NEC 400.7(A)(11). These assemblies provide a safe and convenient way to distribute power to flat-screen TVs without having to run wiring through the walls.
Benefits
Ensures the safety of these assemblies by requiring them to be listed. Eliminates confusion around NEC 400.8(1) by providing a clear exception for these assemblies. Facilitates the use of innovative technologies for powering televisions and components.
Additional Considerations: It is recommended to include a note in the NEC Handbook to provide further guidance on the use of these assemblies.* For clarity, it is suggested to delete the specific product name from the substantiation. Flag for review
