We have received a request by our customers to change our product (about half the size of a household refrigerator) from one high current power cord (plug/receptacle/branch circuit) to two power cords using standard 15 amp receptacles (on separate circuits) to avoid having to do special facility wiring for the high current receptical.
What safety considerations are there in doing this? Internally, one circuit would power a heater, the other would power our electronics. The circuits are not separated in any way in the enclosure so both AC Mains circuits or power cords will have to be disconnected to make it safe to service. Your input would be appreciated. Here is what we are thinking: 1. Input rating labels by each power entry location. 2. Warning label to remove BOTH power cords before servicing. 3. Using two dual pole circuit breaker/switches (disconnect device) mechanical linked together so when you turn off the switch all circuits are powered down. Is this doable?
