You can thank my (ex) wife for it.
Being lazy when I hung my projector I simply ran an extension cord to it, the feed side dropped down behind the rack (for UPS) through a grommet in the ceiling, the rack rear shared the same space as the washer/dryer. When she saw the orange cord hanging down she told me that I was (in theory) a professional and that it was not expectable. Wandering around the garage looking for a way to make her happy I came across an old PC tower with the recessed IEC plug, "Ding! Ding! Ding!". I pulled the plug, went to Lowes for a blank Decora insert and took this project into the Metra Machine shop the following day. Once installed I realized that "Damn, I need to make and sell these".

On one project, the electrician looked at me like I had three heads when I explained why I only wanted an outlet at the TV and bare wires at the junction box I had installed. Now, they talk about it as if it was their idea.... :)

On the same job, they told me the inspector wanted to know why and he couldn't imagine the reason until I went to his office and explained- and these people have the power to allow or deny progress on a project? Incredible.....how do they get these jobs if they don't know what they're dealing with? Is it the 'friends & family' thing, or do they take a test? I'll take that test if it would get me into that job.

Always found it funny that installing an electrical outlet a tv is outside the scope of my licensure.

I can wire up an entire datacenter or TV broadcast facility but an single receptacle? Oh no, you need an electrician for that.

But I can terminate the exact same 3 wires in the context of a power bridge.

Ultimately it makes sense, though.

None of the wires you are allowed to run can have fatal consequences if you make mistakes. For me, that's enough to make sure the uninitiated don't do it.

Sometimes the killer circumstance is not visible. In this case it's the wiring from the circuit breaker to the outlet. Power Bridge wiring uses existing circuit breaker(s) that were installed by... an electrician.

You wrote "an single receptacle" and "outlet a tv." That's the kind of simple small mistake that, given 15 or 20 amps upstream, can kill a person.

Tell them it's a repair- here in the Frozen Tundra, LV isn't licensed unless it's for commercial and we can install power for equipment as long as it's not permanently live e.g., on its own breaker or connected to the existing circuit. Does that mean we don't shut off the power and connect a power inlet? May....be.
