Is it code compliant to tap two 12AWG conductors at the line side lugs of a disconnecting means for a rooftop air conditioniong unit? These two 12AWG conductors would be less than 10 feet, run in raceway to supply a GFCI receptacle.

What size breaker is supplying the circuit.
 
OK, so we have a feeder to a rooftop unit and want to tap this feeder with branch circuit conductors to a receptacle. What article allows this. 240.21 only describes taps to feeders and 210.19 only allows ranges and a few other items, none which allow a tap to a receptacle.Am i losing it or did i miss something.

where does 210.63 or 23(A)2 allow the tap. 63 says its needed and cannot be on the load side of the disconnect.

Which obviously leave the door open for taping it of the line side.

Pretty common around here for roof top units, tap the feeder heading to the roof on the line side of the disconnect and provide OCP for the receptacle.

Two 8AWG conductors protected by 40 amp cb are the feeders to the disco for the AC unit.

In my experience these are feeders running to the HVAC so I see no issue at all, apply the appropriate rules from 240.21. :smile:

I would say these are feeders also and 240.21 only applies to conductors being tapped to feeders.

(B) Feeder Taps. Conductors shall be permitted to be tapped, without overcurrent protection at the tap, to a feeder as specified in 240.21(B)(1) through (B)(5). The provisions of 240.4(B) shall not be permitted for tap conductors.

You definitely lost me as what you posted tells me I can do it. :-? :-?

I am tapping the feeder to power the receptacle.

Ok i'll go along with you that the tap from the feeder to the ocpd protecting the tap are feeder conductors.
