Got a 911 call for the hood I wired in the deli dept. of a mompop grocery store. The FM wanted it wired so the electric range can only be turned on if the exhaust fan is on. Sucks because I used a shunt breaker. Now as well I had wire a contactor in too, could have accomplished ansul and new request using a contactor only. Oh well, it put an extra $400 in my pocket for a couple hours yesterday.
