I am connecting a 220v fire sprinkler pump and a 120v bell. The system has a pressure switch to opperate the pump and a flow switch to opperate the bell.They are packaged as one unit but have two seperate connection points. would it be acceptable to connect the bell to the same branch circuit as the pump? The pump draws 14.5 amps and the bell is less then one amp. I roughed in a 10-3 with ground and was going to put it on a 20amp breaker. It would not be to difficult to run another circuit for the bell from the main, or I could use the 10-3 to feed a 4 circuit panel next to the pump if nessisary. The bell is run in # 12. Is this one utilization equiptment or two? Any reason not to tap the bell into the pump circuit?
 
#1 If the motor went up, you lose power to the pump, you dont have the bell #2 If it came not to be connected as you say.Maybe it shouldn't be?

If the pump motor "went up" the water would stop flowing and the bell would stop ringing. It has seperate connections because the bell can be connected with low volt or line volt. the instructions don't address the issue.Any code reason you could see for it not being connected ?
 
I like the idea of setting a sub panel and feeding off it to the perspective circuits IE: flow and tamper switches.All the ones I have done are 120 v flows and tampers so i have always ran 2 circuits one for each.Just for the reason stated if the only circuit there went out there would be nothing available in the event of a problem.
