means of location - protect the fire pump room / unit from fire by 2 hours FRR when installed indoor or if outdoor, shall be protected from hazard... Ang JP Pwede kumuha ng power supply to the feeder supplying FP but it must be a tapped ahead but within the same enclosure. Hinde appropriate ang explanation mo sa multi building campus style arrangement. No need for a back emergency gen set if multi buildings is supplied by different utilities. Back up is required if electrical system arrangement is LOOPED system. Back up is required if high rise building. No need for back Gen set if fire pump has engine drive back -up. Go ahead , that's good. U provide knowledge and skills sa mga bago. Maganda ref. ang lec ni pareng Mike.

Right now im doing the fire pump room the electrical. For 2 separate fire pumps two different clients in the same building. One 150hp and 60 hp pumps plus the 2 jocket pumps. I love doing the fire pump room.

The locked-rotor current is six times the FLC, so fire pump overcurrent protection must be sized higher than 6 times of the FLC. So in your example, 74.8A x 6 = 448.8A, that's why you will use 450A protection.

sir sa 5:03, yung fire pump supply conductor doon sa pinakita mo sa single line diagram is not permitted sa code, kasi feeder conductor sya hindi service conductor... Unless pang campus style building complex

just a comment at 5:02 although it may have been more than a year ago from then, the slide shows the same note from the other youtube video that says ''2.Ensuring that the fire pump and its jockey pump have ARE LIABLE source of power''. Am I correct to comment that the phrase should have been ''...... A RELIABLE source of power''? Thanks po,
