We are designing a water mist system.
The system is dry type with multiple pumps to pump water in case of emergency.
How should the power connection of water mist system shall be designed.
Per NFPA 750, separate service (tap ahead of the main is not required).
Does the power requirement will need to comply with NFPA 20.
If yes, can't design for LRA (6 time the full load amps) for multiple pump system.
