Hello all ,I am taking a masters prep class here in Washington DC .The Question is ,are you allowed to use #14 wire for rec. taps on a 20amp multi outlet branch circuit in a commerial building with 20amp recepticles ?

I say no ,but the class is using 2003 NEC and keep quoting tap rules and they say yes

jokes on me ,and actually I double posted the topic and a mod deleted the correctly spelled one
,however ,yuk,yuk ,2002 ,1999 code books

The Question however is legitimate ,the master teaching the class insists one can do this and I disagree " use #14 wire for rec. taps on a 20amp multi outlet branch circuit in a commercial building with 20amp recepticles "

Sec.240-3[e] points to Sec. 210-19[d] for rules on branch cir. tap conductors .Exception No. 1 to sec. 210-19-[d] permits 14 awg wire taps for other than recepticle outlets

this is taken from ec-m mag. Mike Holt stumped by the code series .
and is presumably taken from 1999 NEC because it is not worded like that in 2002 or 2005 .

2005 NEC Sec. 240-4 devices 800a. or less the next higher standard overcurrent device rating {above the ampacity of the conductors being protected} shall be permitted to used ,provided all of conditions 1},2},3} are met
1} the conductors being protected are not part if a multioutlet branch cir. supplying recep. for cord- and- plug -connected loads

Sec.240-4 {E} Tap conductors gives loads that can be taped but does not list rec. or multi cir. outlets

NOTE:

To those who see attempts at humor in this thread, but do not understand the joke, do not be concerned. The joke is no longer there. I have edited the spelling of the title of this post. It's first word had been inadvertently misspelled in a way that some thought funny. Others wouldn't find it funny, but rather a bit inappropriate. Since I was one of the later group, I corrected the spelling, and ruined the joke. ;)
 
Re: receptacle taps

Look at the table 210.24 you will see taps on a branch rated at 20 amps can indeed be 14 gauge and can be used with receptacles rated at 15 or 20 amps.

At least that is what get out of it.
 
Re: receptacle taps

Marc, read 210.19(A)(4) Exeption No 1: (c) of the 05 NEC.

Here is a graphic from the 99 NEC, note the article section has changed since then.

Re: receptacle taps

Marc,
That table is a general summary, and where there are more specific rules, the more specific rule prevails. Look at 210.19(A)(2) for duplex receptacles.
