GFCI for kitchen Ansul?

I know 210.8(B)(2), [i.e.- commercial kitchens], says all circuits in commercial kitchen- I assume that also applies to the Ansul system?

Any concerns with nuisance tripping, or just plain tripping during a fire event?

Thanks!

It does not say all circuits, it says "All 125-volt, single-phase, 15- and 20-ampere receptacles"

The fire suppression system isn't ordinarily supplied via a receptacle.

I agree, that section specifically mentions receptacles if it said outlets that would be a different story.
 
Thanks

Thanks

Read the new requirement too fast!
Didn't process the fact that it only applies to receptacles!

It isn't ordinarily supplied with electricity at all, shunt trip breakers and contactors excepted.

There is no load to supply within that equipment, there may very well be a 120+ volt "switch leg" that goes through it.

Yes, but then the question of GFCI applies to the controlled circuit and is of no material consequence to the Ansul system.

Only time GFCI would be an issue would be if the controlled circuit were cord and plug supplied by a 15/20 amp 125 volt receptacle. Of course whether it is something that can even be supplied by flexible cord is another issue, most instances probably not.

How would that matter to the Ansul system? You have a micro switch that's breaking the hot leg of your circuit. Ansul doesn't care what that circuit is as long as you don't exceed the capacity of the micro switch.

It wouldn't be that the Ansul system itself requries GFCI protection it is inherently going to be GFCI protected if supplied by said receptacle because the receptacle must have GFCI protection.

I agree, but the OP asked "I assume that also applies to the Ansul system?" The answer is he's asking the wrong question, like asking if a circuit running to a switch has to be GFCI protected. Your answer at post #2 suggests it doesn't apply since the Ansul would be hard-wired, but the real reason it doesn't apply is that the Ansul system is mechanical-pneumatic and doesn't require electricity to operate.

You can find installations that are solenoid trip from a releasing control panel, but they are very few and far between.
