maliwanag po sir salamat sa video
200A, 3P yung breaker ng main. Pero ang supply is Single phase 😅. Yes gagana pero mapapamahal ka mas mataas presyo ng 3-phase compare sa single phase na breaker.
This channel deserves more viewers, thank you sir for sharing the knowledge
Good job Jun! Nice to see and hear your voice again (watching from California)
Db sir pag feeder paguusapan kpg mag design ng grounding dapat sa table 2.50.3 17? Ung largest service conductor
Good Morning Po!
Sir ask lng po,ano ang possible reason pag may i-plug sa outlet na off ang mga ilaw..
pag 150 kva 3 phase transformer.ilang hp ang kaya
Sir ask ko lang po kung dba dapat e match yung size ng cb sa size din ng wire kasi sa pagkakaalam ko yung no.8 na thhn e 45 amps lng ang ampacity nito tapos yung cb nya ay nasa 40 amps lng tapos ang sayo ay no.8 na wire din yung cb nasa 100amps siya diba malulusaw yung wire pag may overcurrent? Yung 100amps na cb kasi sa alam ko dapat 30mm2 na ang wire na dapat gamitin nito.. Salamat po sana may explanation po kayo sir pra may matutunan nman ako na bago salamat po ulit
Sir ask KO lng po. Ako po ay nangungupahan lng. Nagkaroon po Ng sira ang sub.namin Hindi gumana. So bumili Ng bagong sub meter ung may Ari Ng bahay. Ang nangyari po 21 hrs lng nka 0001.5 kilowatts kaagad kame 2ilaw lng at clipfan gamit namin at buong Gabi na po un wLa po kame sa bahay. SalamAt po SA tugon
Meron po kayo details Ng riser diagram para sa CT cabinet
Sir 60a po main tapos po Yung branch po pwede 40a
Good day po pwede tanung ko lng po pwede po ba emt 3/4 service entrance
❤
same lang po ba ang calculation sa Single phase
Goodday sir. From 2:30 "general lights and receptacles. May I ask why you multiplied it by 10? Thank you somuch
Thank you so much Engr sir for sharing...
boss. iisang service drop ba ginamit mo?
You mized jp kaix rating and overload capacity
Sir paano kung thesame lahat ang kanilang flc sir wala nang ×25% sa pina ka highest flc?i add nlg lahat ang thesame flc at yun na po ang main feeder line nya sir? sana matugunan nyo po tanung ko.salamat po
Thank you po.
Mag tanong LNG a KO Sir,,, paano Kung Meron Sunog tapos hindi gumana si GENSET... Posebli bang mangyari yon or may paraan para maiwasan ang ganyang pweding mangyari .. Yun LNG po Sir,,, at god bless...
My local single phase transformers (primary coil)DO NOT have a neutral back to the substation. The center tap in the secondary coil and the 2nd end of the primary coil are bonded together to the EARTH at the transformer location. Multi point grounding system at every single phase transformer along the way, back to the substation. Repeat, no other neutral conductor? comment please
Sir sana po masagot. Iba kasi sa nameplate ng welding namin. Rated input voltage: 220v/440v Output current range: 100-500A Rated input capacity: 38kva Duty cycle: 35% 38kva=38kw po pero nalilito ako kasi yung supply namin 220 lang. Sobrang laki naman po sa OCPD na gagamitin kung etimes mo pa sa 200%. Patingin po ng calculation nito sir. Thanks
Hi po Engr. Ogarte Ask ko lang po kung applicable po ito sa mga split type or window type na aircon na FLA or Max Current lang po ang nasa nameplate niya at hindi po hiwalay ang current na naka indicate para sa motor at compressor niya? Tapos itimes pa po ba siya sa 125% pag more than 3 hrs po yung normal na gamit ng aircon araw araw? Bale FLA x (125%) x (175% to 225%) po ang OCPD rating niya? Thank you po ng marami sir napaka informative at nasa standard po lahat ng video niyo, keep it up po.
pano po pag LINE to LINE ung kuryente sa isang bahay pano mawawala ung ilaw?
Galing👏👏 ganito dapat mga content..
Good day po engr. If 3sets of conductors, 3 diff lines (RYB) po ba per conduit or same line (RRR-YYY- BBB per conduit? At yung nuetral...
Branded naman yung mga led lights ko pero ganun pa rin
Ang weird talaga sir, ang daming computation na lumalabas diko n alam ano ba tunay, un 746 watts, di na daw dapat gamitin un, dapat nk base na sa PEC . Weird talaga kung kelan my inverter n dun pa tumaas breaker. Samantalng noon 80s 15 at 30 amper pwede na. Ganun din ba sa 3horse power n motor my napa nood ako 50 ampere un ginamit n breaker 3.5 amp un wire sa PEC din kinuha computation.
👍🏽👍🏽👍🏽
Ang baba pala Ng breaker Ng HVAC ..unit baka window type acu lang Yan compute mo boss at split type..sa tingin ko boss Yung HVAC sa mga industrial at hight rise building..yang computation mo boss for dwelling unit load acu ata Yan .kasi Yung title mo HVAC ..maliit pala Yung load Ng HVAC boss ?
Sir salamat po sa video, ask ko lang po about sa looping ng wire sa bungad ng service entrance, is it needed or wala sa PEC yun?
"Note 4. Motor short circuit contribution, if significant, may be added at all fault locations throughout the system. A practical estimate of motor short circuit contribution is to multiply the total motor current in amps by 4. Values of 4 to 6 are commonly accepted." Engr. tanong ko lang po sana, sa Note 4 ng Cooper Bussman article yung motor contribution is estimated to be 4 x total motor current in amps. Bakit po sa calculation nyo ay full-load current ng transformer sa secondary yung ginamit nyong value para i-multiply sa 4? Dahil po ba walang given na motor data kaya ginamit nalang yung FLC ng transformer? Thanks
SIR PANO PO MAG SIZE NG GROUNDING
oo nga po ,ENGR... KAYA MASA MAGANDA , ANG LED SA 220 TO GROUND, DI PWIDI SA LINE TO LINE 110/110...
Good morning sir. New subscriber nyo po ako. Paano po Kita ma private massage through chat?
ano po epekto nito sa 3phase motor load
Engr. Dito sa probinsya or rural areas di naman required ang nema 3r,.Ngayon Tama ba na Yung service drop wire ang neutral ay deritso sa ground rod at kung sakali maglagay ako equipment grounding at nakabonding nalang sa ground rod? Thank you and Gob Blessed po
Ask lang po pano po kumuha ng licence ng register electrician
wala yan sinabi mo ...alam mga tao yan......
hi sir jhun bakit di kayo nag apply ng 1.25 para sa minimum conductor ?
Sir. Bakit po iba ang reading ng main meter sa sub meter? Ano po problema
Good day. Sir. Nasa pec bayang value ng C?
sir salamat sa mga advices.. may tanong lang ako pahabol, mag kano ba daw prisyuhan pag RME na ang nag iinstall ng bahay? mag kaiba ba ang prisyo per devices sa RME at NCII electrician. dami kasi nag tanong. kasi pag rme na daw mahal na.
sir pwde po ba e embed yung tubo ng service entrance?
.
Pagganyan po ba sir set up.. kahit wala na Equipment Grounding Conductor?? Kasi plastic naman yung junction box tsaka utility box. Wala din po lagayan ng EGC sa device na ginamit po.. ok lng po ba walang EGC?
Sir tanong ko lang if di ba masusunog yung cable natin since sa FLC lang sya nakabase compared sa OCPD natin na sized at LRC?
Sir tanung lng po kung ang mcb kopo ay 40amp at maglalagay poko ng 3pcs na 30amp para sa spo at 3 20apm sa co at 3 15amp para sa ilaw po at ang wire kopo ay #8 thhn po kaya poba un load po ty
