If I took a device, say a transmitter, that is not rated for a Class I, Div 1 area and place it
in a explosion-proof enclosure/housing, will that make it pass for a Class I, Div 1 approved device
or does it have to be inspected by authorative body like UL or something? If a device is explosion-proof, does that make Class I, Div 1?
If a device is explosion-proof and only handles 120Vac, can that device be used in a Class I, Div 1 location?
Or does the voltage level do not matter as long as it is explosion-proof? If that is the case, then why use intrinsic safe circuits if being explosion-proof is all that is needed?
