Since it's high voltage you'd want the electrician to do it. I have just provided the electrician with the part numbers. To make it even easier you might want to just provide them the inlet part which is cheap. Most electricians have never heard of an inlet so you can always expect a blank stare.

I think it's worth doing for just about any display that's tied into an A/V system IF it's new construction. It doesn't cost any more to wire it this way versus putting in a conventional outlet.
