- Watch as Paul Abernathy talks about how to size a simple branch circuit to a motor. If you want a more in-depth analysis of motors then watch the full-length video on motors at / masterthenec
Your videos are extremely helpful and easy to follow, I take my test in March! Thank you for taking the time to make videos like these!!
I take my test in 6 days!! Whatever happens, I want to thank you!! All the free, great info you put out here for us is great, and is very nice of you to do.
Stay Positive and NAIL IT FELLA....
Did You Pass ?
Good explanation about single phase 230v to choose proper conductors. Thanks for showing this vedio
Be sure to watch our other longer video on Motors.
Great job, way to go
Thank You. Hope you found it helpful.
Both hot wires should be 10AWG?
Greetings - This is a simple branch circuit so yes all branch circuits associated with this example are 10 AWG CU. The sizing of the branch circuit is per 430.22(A) in this example.
Hi master , can we use the flc on the table for sizing the conductor and CB of airconditiong?
Use the nameplate on the equipment. No need to over complicate the application. It will give minimum circuit ampacity and maximum overcurrent protection on the nameplate...Stick to that data.
Thank you! What about an AC Servo Motors. Do they obey the same rules as regular AC motors? If the manufacturer of the VFD or servo motor Drives recommends nominal of MCB. do I need to consider these recommendations?
I would contact the manufacturer of the VFD for additional instructions. Also VFD are covered in Article 430, Part X and in 430.6(C) as well.
@@MasterTheNEC Ok thank you! I am on UL508 A project and UL says nothing about servo
