in lieu of the PowerBridge solution for code-compliant wiring that will alllow a projector to be fed conditioned power from some distance away, why not buy 14/2 stranded wire, CL3 listed power cord at Home Depot, terminate one end in a male plud and terminate the other in the projecor?

warranty issues? code issues?

my neighbor just had his basement pre-wired and in the wiring bundle is a power cord with unterminated ends.

interesting.

any one do this?

if this cord is going inwall then it will be a code violation

"Cord" products are not approved for in wall wiring. Even the very commen practice of running an extention cord above a drop ceiling is illegal. Nor can in-wall class 1 electrical wiring exit the wall as a cord. IOW, you can't have a piece of Romex or MC cable poking out of a wall with a plug attached to it. Some members here has posted this as a solution but it's illegal.

Now some people rightly point out that many extension cords are much better insulated and rugged than Romex cable. So why is this not allowed? It has to do with testing. In wall wiring is subjected to many unique tests by UL to determine it's safety in a concealed space. For example thinner insulation allows the conductors to cool faster than conductors burried under several layers of thick plastic. The plastics used in in-wall wire have specific properties selected for low toxic fumes when burned. Likewise Romex cable would be a poor choice for a garage extension cord. It would be damaged very quickly from ordinary use.

There is a way to make a code compliant low cost DIY "Power Bridge" with ordinary home center parts.

1) Install the projector outlet in the ceiling and run the Romex or MC cable back to another wall box by your rack location.

2) After drywall and paint attach a metal "add on" box to the recessed wall box.

3) Through a knockout and clamp take a 14ga cord and splice it to the Romex or MC cable. Be sure to attach the ground wire to the metal box as well. It's Ok if the in wall box is plastic but any exposed metal must be grounded.

4) Place a blank cover on the extension box. The cord end now plugs into your power strip or conditioner.

You may still get flack from the inspector since such a setup is very rare in residential but AFAIK, this meets NEC.

Some people have found blank plates with a knockout. Or they have drilled out a solid plate. This may or may not pass an inspection. You still must ground the metal plate (don't even condiser a plastic plate, it's too fragile to attach a cord to). It is technically against code to modify a listed wiring device such as drilling holes in a blank plate. Yes it sounds silly but once you (or even a licensed electrician) modify a listed product, it loses it's listing status and the manufacture is relieved of any safety liability.

understood thanks for the advice
