I have been researching the need for Class 2 wiring on our conveyor equipment. It seems that photo-eye and other device manufacturers are adding a "class 2" rating to the cables attached to their devices in order to get a UL listing. It has been our opinion that we need to provide class 2 power to these class 2 devices. This includes CanBus cabling used for communications on the equipment.
My questions:
As an industial equipment manufacturer, are we not bound by NFPA 79 as opposed to the requirements of the NEC article 725?
Does the fact that the device manufacturers class 2 listing on the cable trump the requirements of NFPA 79?
I feel that I am getting forced into Class 2 requirements per NEC 725 because of the devices, when our general wiring methods should be guided by NFPA 79.
