Good day, Sir Randy! Thank you po sa informative content. May I ask po kung meron po bang way to determine the right size of the jockey pump and fire pump (in horsepower) to be used? Thanks in advance!
Meron sir way para ma determine ang requireed size ng jockey pump at fire pump pero more on mechanical side na yun sir kasi need nila i consider lahat ng mechanical aspects like laki ng building, length and size ng pipes, ilang sprinklers etc.
@@RandyAmorchannelHi Sir Randy, gets po, thank you po, akala ko po meron din po tayo as EE to determine the size. Anyway po, sorry po newbie lang din at baka trivial question/clarification, clarify ko lang po Sir Randy na sa example niyo po, yung 50mm2 po ba ay connected doon sa 600A fuse? If so, hindi po ba mababa yung wire na ‘yun in case po na magka-LRC? Thanks po ulit in advance!
@@magicxrps4676 yung OCPD required para sa firepump is naka size base sa LRC para masigurado na hindi magti-trip or mag blow yung fuse during start-up, pero yung stating kasi ay tumatagal lang ng ilang segundo then after that babalik na yung current sa rated FLC ng motor so ok na yung conductor. Kapg nag trip or pumutok kasi yung fuse ng firepump motor during starting wala ka ng fire pump to protect the building
well explained sir, naliwanagan ako sa sizing, ask ko lang din po need ba sariling service power from Utility si Fire pump? and magkano kaya pag mag-aapply kay coop nito? thank you sir
According to PEC yes kailangan. May naging project ako sa isang industrial park sa Laguna 3 years ago ang design ng fire pumo supply ay galing sa MDP na nasa loob ng building, pinabago ko pinakunan ko ng supply direct from utility. Pagdating naman sa coop wala akong idea sir.
@@markbibar1185 para saan mo sir gagamitin yung total load? Kasi kung sa laod schedule mo gagamitin no need to calculate kasi may FLC kana galing sa table. Kung input power naman kailangan mo gamitin mo yung hpx746/eff.
Sir may tanong lang ako dun sa example mo for conductor size yung FLA sir is 140A use 50mm² wire(magsusuply sa pump from OCPD) yung wire ba sir from genset to OCPD sa example mo gagamit ba ako ng wire na 2set of 175mm²? TIA
Good day sir. Sa conductor naman from genset to OCPD ng fire pump, hindi mo kailangang i oversize yung conductor to suit the OCPD ng fire pump. 125% lang ng FLC ng fire pump motor ang minimum ampacity ng conductor.
@@RandyAmorchannel thankyou sir akala ko kasi kung ano yung ampere trip ng OCPD breaker yun ang gagamitin kong wire size. thankyou po pwede ba kitang i message sa fb sir may kaunti lang akong iclaclarify
Wala akong chart sir, meron akong table ng wire sizes sa PEC, kung gusto mo ng wire table pwede kong i send sayo via email. Paki bigay email address mo i send ko sau
@@pleasebelievedme3745 ung 350A at 220A ba na tinutukoy mo ay breaker rating? Check mo muna kung yung 350A na braker ng fire pump panel is kayang i handle yung locked-rotor current. Kung pasado yung 350A sa LRA ok na yun di mo nakailangan ng another source kasi as per PEC dapat ang fire pump supplied directly from utility.
Thank you sir sa question. Actually, ang SPD sa fire pump controller ay new mandatory requirement sa NEC 2017. di ko lang sure sa new PEC kasi wala akong copy ng latest edition ng PEC, pero dahil sumusunod lang naman ang PEC sa NEC, malamang required na din. From NEC 2017 "695.15 Surge Protection. A listed surge protection device shall be installed in or on the fire pump controller." Pero check ko sa PEC 2017 pag nakakuha ako ng copy then update kita.
Question, pwede for the sizing of the conductor of fire pump controller is not included yung jockey pump since hindi naman magsasabay ang jockey and fire pump sa actual? Another question, at what percentage yung sa Voltage Drop ng FP, it is 5% or 15%?
Sir as per PEC mandatory na ang conductor ay sized at a minimum of 125 of the sum of the FLC ng fire pump at ng jockey pump. When it comes to voltage drop naman, yung 15% maximum ay under motor starting condition lang pero pag ang motor ay umaandar up to 115% of FLC, maximum voltage drop ay 5% lang.
Hello sir. Thanks for asking the question. Actually, walang sinabi sa PEC or sa NEC tungkol sa overcurrent protective devices ng controllers. Pero sa NFPA 20, which is the standard that covers all aspects (mechanical and electrical) of fire pump installation, sinasabi na hindi dapat lagyan ng overcurrent protective devices ang controllers. Please refer to below section of NFPA 20 "10.3.5 Protection of Control Circuits. 10.3.5.1 Circuits that are necessary for proper operation of the controller shall not have overcurrent protective devices connected in them." I hope this answers you question sir. Have a good day
Yung 409A ba sir ay yung result ng calculation ng locked-rotor current? Kung Ang rule kasi sa OCPD ng fire pump is dapat kayang dalin yung locked-rotor current ng fire pump, jockey pump at accessories, hindi base sa FLC. REfer to Table 4.30.14.5(b) ng PEC sir para sa LRA values ng LRA
@@RandyAmorchannel yes po locked-rotor current po yan nag based po ako sa example nyo so if 409amps nga po lumas need ko po ba is 500amp or okay na 400amp? need for 50hp fire pump and 10hp jockey pump
@@jonathans2888 sir, kung titignan naten maliit yung 9A na sobra sa 400A, pero PEC and NEC requirement is not less than the "sum of the locked-rotor current of the fire pump motor(s) and the pressure maintenance pump motor(s) and the full-load current of the associated fire pump accessory equipment when connected to this power supply". For the sake of following the provision of the code, I would suggest to use the next higher standard rating which is 450A according to PEC 2.40.1.6. Sana nakatulong yung sagot ko sir sa question mo.
Sir linawin ko lang, bakit may fuse na may CB pa? And one more thing sir, ang OCPD ng fire pump ay hindi pwedeng nasa panel board na nasa loob din ng premises na pinoprotektahan ng fire pump.
@@RandyAmorchannel sir dun po ba example nyo and wire nyo is only 50mm and yung fuse is 600amp? also if OCPD is not located in the panel board saan po kumukuwa ng supply mga fire pump? sorry sir newbie
@@jonathans2888 yes sir sa example ko yung conductor is only 50 sq. mm kasi yun ang corresponding size para minimum of 125% of sum of the FLC's ng fire pump and jockey pump. Pagdating naman sa OCPD, ang sizing ay base sa LRA hindi sa FLC kaya malaki talaga para masigurado na anytime na kailangan ang firepump ay aandar at hindi mag ti-trip CB or puputok ang fuse due to locked-rotor current . With respect naman sa location ng feeder ng fire pump, hindi allowed na kumuha ng supply ang feeder sa distribution board na nasa loob din ng building na pino-protektahan ng fire pump kasi pag nasunog ang building at nag trip ang feeder ng fire pump or yung main CB nd distribution board, eventually hindi mag o-operate ang fire pump so wala din silbi masusunog din ang building. Yung project ko before sa Laguna nung ni-review ko yung electrical plans na gawa ng EE na gumawa ng plano and take note pirmado pa ng PEE yun, nasa loob ng building ang supply ng fire pump at ATS, pinabago ko pinakuha kong supply sa mismong utility after ng metro derecho sa pump room at pinalipat ko din yung ATS sa loob ng pump room, Pati yung generator supply derecho din sa ATS sa pump room.
