Electrical NEMA rating for installation in ESFR

[Barry Biglari]

I would appreciate any hints on requirements for NEMA rating of electrical equiment/devices/lights/raceways in buildings/areas with Early Suppression Fast Response (ESFR) sprinkler system.

why would the type of sprinkler system make any difference?

the sprinkler is there to protect the building from burning down. if it happens to damage some equipment along the way, that is just too bad.

Apparently the system is high pressure almost like hose down!

No other requirements needed.

No. We installed one in opur printing distrabution center. It does not require any changes. It works by dosing the effect area instead of drenching the whole building. Usually only 12 heads will go off at one time.
