I was recently asked by an process operator to install a disconnect switch at equipment location.
Conveyor motor is located in a Class 2 Div 1 area.
Questions:
1. Can't tell if the motor is rated for area classification, is there something on the nameplate I can look for? I read "Class G", is this the right application?
2. Do I need to specify a NEMA 7/9 for disconnect switch or can I get by with a NEMA 4X?
3. There is a handstation control associated with equipment, I assume dust ignition proof will be required.
4. Did not see any conduit seal offs? Is this req'd for class 2 or only a requirement for Class 1?
