Preface: I have limited experience with pumps and motors associated with the fire sprinkler system.
On a project we recently completed the building inspector had issue with the sprinkler pipe travelling though the insulated attic. Rather then heating and/or insulating the attic the customer opted to convert the sprinkler to a dry system. They installed a pump to regulate the air pressure in the pipe. I became aware of this change the next day, also coincidentally the day the fire and electrical inspector were due to visit the site. So i ran 12/2 MC with a dedicated 20A breaker and locked it in the on-position. I used a 20A commercial grade toggle switch as a disconnect (Labled as a disconnect with the circuit number and the device it services) just to get the job done quickly with what I had on the truck. Nobody even looked at it or questioned it or asked me about it and there was no issue...
i'm not worried about using a switch as a disconnect for a motor. I'm more worried about the fact that its associated to the sprinkler system.
My question is:
"Is the 20A commercial grade toggle switch suitable for use as a disconnect for this pump associated with the sprinkler system."
