i liked it so much how you explained and presented your discussion. It is so basic and well discussed. I can't wait to hear from your tutorials again. I've learned a lot. God bless you more.
@@markmacatuno3218 sir yung dereating factor is ginagamit sa cable sizing depende sa certain conditions of installation. Assuming na nakapag size na tayo ng conductor, ang voltage drop calculation naman sa video na ito ay ginagamit para malaman kung tama ba yung size na ginamit naten to make sure na hindi tayo lalampas sa approved voltage drop na required ng PEC. So for this video, hindi na naten pinakita yung application ng derting factors.
Thank you very much for the very clear, detailed and straight forward video lesson. This helps me a lot on my studies. May I kindly consult the question below? NEC Table 9 have a title of: Alternating-Current Resistance and Reactance for 600-Volt Cables, "3-Phase", 60 Hz, 75C (167F) - Three Single Conductors in Conduit Can we use also the NEC Table 9 for 1-Phase circuits, even though the title indicates "3-Phase"? Thanks again and more power to your channel.
Because the method using Z values in table 9 of NEC is just an approximate method, you may apply the same value for single phase. Alternatively, you can use the DC resistance values in Table 8. The values in both tables are very close and wouldn't make much difference in the calculations.
Check nyo muna sir gaano ba kalayo yung outlet nyo mula sa breaker? Saka anong size ng wire ang ginamit? It is very unusual na 30V ang nawawala sa linya as voltage drop.
Mas mabuti ba gamitin yung unang method for safety purposes with additional cost? Sabihin na natin sa unang method 3.2% lagpas na sa 3% yung VD which in this case gagamitan mo ng 1 up higher na wire size. (From 5.5, gumamit ka 8.0) Tapos sa pangalawa ang pangatlong method nasa 2.9% at 2.8% respectively yung VD which is pasok sa 3%. (Which is ginamitan ng 5.5) Yun nga downside, mas mahal na pag ginamitan ng unang method pero safer na?
Either method sir acceptable, nasa designer na yung decision, kung yung advantage ng pag gamit ng isang method outweighs the disadvantage, use that method. Meron kasi tayong tinatawag na value engineering pero sa design laging number one consideration yung safety ng installation, secondary lang yung cost.

Thank you sir and God bless
Very great electrical toturial,npakahelpful po nito sa bahay,thanks for sharing this knowledge idol
This is very informative. Nacurious ako bigla. Salamat
Nice video tutorial Engr. 👍🏼
Salamat sir
salamat po sa iyung suporta tnx for sharing andito n po ako bgong kasangga keep safe po and keep vlogging
Nice video sir! Malinaw,detalyado at di mahirap intindihin, subscribe po ako sainyo Engr.
Salamat sir. God Bless
Question lang po Engr , bakit po hindi na sya ginamitan ng de-rating factor?

Thank you ulit sir!!
Napaka informative Ng videos nyo Po keep uploading salamat
Engr big tnx sa share mo na calculation clear explanation
Nice content po idol keep uploading informative videos Godbless
Gandang content mo bro. Keep vlogging
thanks for sharing your informative vlog content god bless
bro i want to learn basic reading of voltage using this equipment . keep on sharing.
Keep blogging po at ingat sa mga circuit nayan
Very informative and clearly explained
thanks sa sharing idea Boss. Godbless po
eto ang maganda sa mga eletrikal.
very informative information sir i like it .
New subscriber master sir
Thank you so much sir
Thanks po sa mga info.
Nice bro thanks for sharing
Keep on posting your videos po...new friend here
Sir saan po nakuha ang theta na 31.79 deg. At saan din po nakuha yong Sin theta na 0.527
keep it up lods. godbless
good job

@@RandyAmorchannel I see, that make sense, thank you very much for the response
Keep it up
Good day Sir, paano aayusin ang mababang voltage sa outlet ko. 230V ang reading ko sa breaker, pero 200V nalang pagdating sa outlet. Thank you po.
Check nyo muna sir gaano ba kalayo yung outlet nyo mula sa breaker? Saka anong size ng wire ang ginamit? It is very unusual na 30V ang nawawala sa linya as voltage drop.
Sir kung yung length magiging (meters) magiging 305 ba yung 1000?
@@jolfre5221 Hindi sir Kasi Yung formula is para Sa length in ft so Kung may length ka in metres in convert Mo sir Sa feet
Thanks sir
Bro pwede ko ba malaman anong book ang gamit mo? Thank you 👍
No specific book sir madami akong binabasa mga reference books at standards iba iba sir. NEC and IEEE color books good reference sir
Dine na po ako sayo inyo

Sir yong bang cos0.85 yon ba yong pf or constant.
yung 0.85 po yung power factor na yun di na kailangang kunin yung Cos nun. Nasa Table yun sir sa NEC. Salamat po sa question.
@@RandyAmorchannel sa Table 9 ba sir.
@@gemmaromero4433 Opo s aTable 9 po ng NEC under sa 0.85pf column
Bakit ako natatawa 😅
Kasi ang dapat mong panoorin ay yung pang-comedy lang, ito kasi pang may utak!
@@joelcastillo3902 may utak ka n pla nyan sir? 🤣 🤣 🤣
Parang hindi kasi obvious n may brain k sir ei. Minsan pahalata mo nmn 😂
