To determine what size feeder is needed to carry a certain amount of current, the temperature rating of the conductor and associated terminals must be taken into consideration. Factors that impact feeder sizing include conductor ampacity, equipment terminal temperature rating, continuous load factors, overcurrent protection requirements, conductor insulation temperature rating, ambient temperature corrections, and conductor bundling adjustment. At first glance all of this may seem a bit overwhel

Sizing conductors and short-circuit ground-fault protection for A/C equipment is Easy! All you need to do is follow the equipment nameplate! The nameplate short-circuit/ground-fault protection is sized to 225% of the load [440.22} and conductors are sized to 125% of load [440.32]. Understand that 240.4(G) overrides the limitations of 240.4(D) and that the A/C equipment has internal overload protection. Note 1: If the wiring method was NM Cable (Romex), then the conductors are sized to 60C column

The first time you’re called upon to size a conductor and overcurrent device for central air-conditioning and you look at the nameplate requirements that clearly state that a 10 AWG copper conductor and a 50A OCPD are required, it may contradict everything you’ve learned about small conductors. In fact, you may adamantly insist that 6 AWG is required by the Code and you’d be wrong! Learn why in this video on section 440.4(B) of the NEC... https://www.mikeholt.com/newsletters.php?action=display&l
