Hello everyone, if you want any topics in mind related to our electrical code, don't hesitate to request them. Thank you all for watching; move videos to be posted.
Voltage Drop is mostly applicable why we need to increase wire size higher than min. wire sizing., But not totally 8.0mm2 is wrong for a 50 Amp. Circuit breaker, We must know the derated value for 50 Amp , Circuit Breaker, Please consider the Table for ur reference,
Hi Peter, thank you for your comment. My reference was based on the electrical code, specifically subsection 1.10.1.5(C)(1)a. For device or equipment terminals rated 100 A or less, wire sizes shall be based on the 60 °C temperature rating listed in PEC Ampacity Table 3.10.2.6. Equipment terminal rating is one of the most common misapplications of conductor temperature ratings that occurs when the established temperature rating of the equipment termination is ignored. Also, how come the derating of circuit breakers makes 8.0mm2 correct for 50A? kindly share references, Thank you.
Using NEC 80% Rule Wire ampa ampacity for 50Amp = 50/0.8 = 62.5 That meansyou should use a wire that can handle 62.5 Amp as a 50A wire. The closest wire to use is #6AWG , since it has ampacity of 65A.
Importañt note to remember that circuit breaker must be use only at 80% of its overall rated ampacity, That is what we call derated value of CB.Is that ok for you sir?
Very informative. Nice video.
Thanks
Very knowledgeable. I'm looking forward to more videos.
Thanks

Good tutorial idol
Thanks
Very informative!
thank you
What is the catch of using THHN and THW if the ampacity cannot be used based on their respective temperature?
If temperature rating of THHN cannot be used, why this conductor is most popular? What are the advantage?

No sir, 50 Amp. Wire is for #6AWG not a 50 Amp breaker has deratedvalue of 80%,
@@peterlabasa4660 will you please explain why we drerate the breaker?
Using NEC 80% Rule
Wire ampa ampacity for 50Amp
= 50/0.8 = 62.5
That meansyou should use a wire that can handle 62.5 Amp as a 50A wire. The closest wire to use is #6AWG , since it has ampacity of 65A.
