salamat sir sa dagdag kaalaman, next vid sir sana po mga component na gngamit kapag jockey pump set up or with fire pump set up po. kagaya po nung nasa unang video mga piping diagram po.
sir Juluis, dba grounding cable 1purpose will be for system ground. If the ground fault protection is disabled, is grounding cable ba still needed? Thank you
sir, papaano kung customer owned yung transformer or tawag natin sa pinas is owner supplied transfomer, allowed pa rin ba naka tap yung conductor sa secondary side ng transformer?
Good day sir Julius Salutan Thank you sa dagdag kaalaman. mabuhay po kayo.Question lang po Sir. Paano po i compute ang Overcurrent Protective Device shall not open within 2 mins at 600% of the FLC of the Fire Pump Motor(s)
There is a special construction for fire pump motor controllers which address all the requirements from NFPA 20 which is different from typical industrial motor controllers. OPD not to trip in 2 minutes at 600% of the fire pump motor FLC is being design/set on the electronic relays which is already part of these controllers. These controllers are type tested.
yes, iba kasi ang pilisopya pag dating sa fire pump..... di baleng masunog na yung motor kesa masunugan ka ng building..... abusuhin mo na yung motor..... tandaan mo, malaki na ang sunog pag umandar na ang fire pump
good question, 3-wire lang naman. ang equipment grounding conductor is not part ng number of wires.... tandaan, hindi pede gamitin ang equipment grounding conductor sa circuit.
salamat sir sa dagdag kaalaman, next vid sir sana po mga component na gngamit kapag jockey pump set up or with fire pump set up po. kagaya po nung nasa unang video mga piping diagram po.
Sir galing mo mgturo
Salamat po Sir sa dagdag kaalaman.Sana marami ka pong videos na iupload na reference lagi ang PEC at NFPA.
Nice po kapatid..Shout out po..
Thank you sa mga dagdag kaalaman Sir. Godbless po 😇

sir, alin doon yung OPD na tinutukoy mo, yung bago mag ATS or within/built-in sa loob ng fire pump controller... magkaiba kasi ng approach kasi.
sir baka pwede rin po madiscuss sa next video niyo yung protection device coordination po..thanks po
Isa sa mga topic ko po yan ang coordination study using etap. Sa mga susunod ko pong mga videos related sa etap ay gagawa ako noon
@@juliussalutan8006 salamat po sir...godbless
Kailangan ba ng thermal overload relay sa fire pump control knowing na kailangan tumakbo ang fire kahit lumindol or kahit masunog yung motor
it is prohibited to have a thermal overload as it requires to limit more points of failure
yes, iba kasi ang pilisopya pag dating sa fire pump..... di baleng masunog na yung motor kesa masunugan ka ng building..... abusuhin mo na yung motor..... tandaan mo, malaki na ang sunog pag umandar na ang fire pump
BAKIT PO 4 WIRE ANG GAMIT SA 3PHASE NA PUMP MOTOR? NEUTRAL PO YUNG ISA? MERON NAMAN PONG GROUNDING.
good question, 3-wire lang naman. ang equipment grounding conductor is not part ng number of wires.... tandaan, hindi pede gamitin ang equipment grounding conductor sa circuit.
Can you please edit this video in english
Pahingi diagrams jockey sir.with pressure switch
