Would it be proper to tap a 20a circuit at each outlet with a short (6 inch) piece of #14 wire to install a duplex 15a receptacle? I seem to remember a discussion on this before but can't find the code reference. Only thing I find is 210.19(A)(4)(c) and it says "No" Comments please.
There is an exception for lamp holders and luminaires but I don't think that extends to a receptacle. Receptacles are the reason for 240.4(D) in the first place IMHO. The installer has no control over what a user does so they build the 80% safety factor into the installation.

Code is pretty blunt in saying that you can't do this with receptacles...you can put 15 amp receptacles on a 20 amp circuit, but you can't pigtail with #14- even though general tap rules would otherwise allow it.
I, for one, do not understand why code denies this practice. Are they trying to prevent the use of cheap 'back-stab' receptacles on 20 amp circuits? Your guess is as good as anyones'.

In George's question he implied that all of this tap would be inside a box so the hazard is probably not there but it is still a <technical> code violation. If this was simply to pigtail in a receptacle I doubt anyone would ever actually have any problems.
