While your assumption that 14# cannot be spliced to a 20A circuit is correct, I think there is a more applicable reference-but I am too tired to find it at the moment. Sorry, brain fart.Am I correct that 210.19 (A) (2) does not allow 14 Gage conductors to be spliced to 12 Cage conductors for the attachment of a 15 Amp receptacles when they are attached to the 20 Amp small appliance branch circuit of a dwelling?
While 14 and 12 can be spliced (as long as the over current device is rated 15 amps or less, the fact that you are referring to a SA circuit would prohibit this.Am I correct that 210.19 (A) (2) does not allow 14 Gage conductors to be spliced to 12 Cage conductors for the attachment of a 15 Amp receptacles when they are attached to the 20 Amp small appliance branch circuit of a dwelling?
I am going to say (D)(3) instead of (D)(5) for protection of a 14 AWG conductor.240.4(D)(5)
The jumper to the receptacle is not a "tap" it is a branch circuit conductor and cannot be smaller than #12 for a 20 amp circuit. The branch circuit taps in Table 210.24 are the taps that are specifically permitted by the exceptions to 210.19(A)(3) and (A)(4)....
210.24 Branch-Circuit Requirements Summary - Does not include 20Amp circuits for such a tap -- ok to use 14ga when pigtailing to a duplex though per TABLE 210.24 Summary of Branch-Circuit Requirements
Good point - I'll let Kwired respond to his method
This is becoming less common as many of the luminaires that were connected in this way are typically being replaced with T5 HO luminaires - which don't meet the requirements of the section, but was common for HID luminaires. I specifically remember one time installing a 30 amp circuit and tapping 15 amp receptacles for each luminaire location, but according to 410.62(C)(2) should be able to do the same for up to a 50 amp circuit.(2) Provided with Mogul-Base, Screw Shell Lampholders. Electric-discharge luminaires provided with mogul-base, screw shell lampholders shall be permitted to be connected to branch circuits of 50 amperes or less by cords complying with 240.5. Receptacles and attachment plugs shall be permitted to be of a lower ampere rating than the branch circuit but not less than 125 percent of the luminaire full-load current.
