Sealing Fitting at Class 1 Division 2

[Sykoku]

I have some questions about sealing fitting refer to NEC 501.15(B) for Conduit seal, Class I Division 2.

In my plant, we use Motor Explosionproof and at terminal box of motor we use explosion-proof enclosure. The motor is located in Class 1 Division 2 area, in this case sealing fitting is required to install at the terminal enclosure or not? if installed it should be installed within 450 mm (18 in) at the enclosure or not? the terminal is a normal terminal, does not have any certificate or protection technique.

Thanks lot for your support

We need to know more about the motor.

A squirrel cage induction motor does not need to be explosion proof or require a seal-off in a D-2 area unless it contains other devices (such as a thermal switch).
