hi
i am learning the trade and i love to learn new things. can someone help me. i was talking to one of my co-workers. he was telling me about how in commercial kitchens, the exhaust canopies power is shut down when the fire system goes off. they have there own panel and the circuit breakers have shunt trips. i hope i do not sound dum, but what are shunt trips? how are these systems wired to the fire system? can anyone help or give me a link to a site about this. thanks guys
