501.10(B)(4), 501.15(B)(1) - Class I Division 2 conduit seals entering enclosures

[Dale001289]

Just want to be completely sure on this one:
A switch (or other arcing device), installed in Class I Division 2 location, with factory sealed or hermetically sealed contact block, does NOT require an explosion proof enclosure and therefore, does not require a conduit seal....

Correct.

Thanks -
EDS series is also good for Division 1. I was looking at Allen-Bradley, Bulletin 800G Pushbuttons, with non-metallic housing for Division 2 applications.

For Class I, Division 2 applications, I use the 800H operators with the sealed contact blocks (800T-XAP) in the Rosite enclosures.
