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

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

Factors that impact conductor sizing include not only conductor ampacity and equipment terminal temperature rating, but also the conductor insulation temperature rating. In this video we discuss Table 310.4(A) which provides information on conductor insulation properties such as letter type, maximum operating temperature, application, insulation, and outer cover properties… | Mike Holt Enterprises

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

Fire Pump Circuit Sizing is Mind-Blowing! Short-Circuit/Ground-Fault Protection Size - Protection must have an ampere rating not less than the nameplate locked-rotor current of the fire pump motor (between 6 to 8 times motor FLC) [NEC695.4(B)(2)(1)]. Conductor Sizing - Conductors must have an ampacity of not less than 125 percent of the motor full-load current rating in accordance with 430.22 [NEC 695.6(B)(2)]. In this example, a 34A FLA/183A LRC fire pump motor requires 200A protection [240.6(A

Mike Holt's Electrical ToolBox. I created an amazing app for the electrician, inspector, instructor, contractor, and engineer. The app contains conductor sizing (including voltage drop limitations), circuit protection sizing, race sizing, equipment grounding conductor sizing for electric heating equipment (commercial and Residential), air-conditioning equipment, motors, Transformers (commercial), and dwelling-unit service calculations and sizing. As for me and my house, I will serve the Lord [Jo

A fire pump wouldn’t be of much use during a fire if the circuit conductors that supply it failed. Sizing these conductors isn’t the same as sizing other motor conductors. Watch this video to ensure that you’re sizing fire pump circuit conductors correctly. #2020NEC #NationalElectricalCode #ElectricalTraining #ElectricalIndustry #ElectricalSafety #NECRequirements | Mike Holt Enterprises

Although the rule of six grouped service disconnects didn’t change, disconnects are now required to be compartmentalized to reduce the hazards associated with arc-flash and arc-blast. This might not seem like a big change but, it makes most of the available multi-meter centers and switch boards ineligible for use to meet these requirements. | Mike Holt Enterprises
