I have a project where we are using flexible cord sealed at the termination of a submersible pump in a CID1 wastewater wet well and routed to a pump control panel via a conduit sleeve. The flexible cord is listed and installed per NEC 501.10(A)(2) and 501.140.
My question regards the classification of the area around the above ground conduit sleeve stub-up. There is no conduit seal-fitting installed, only duct seal. If the wet well is classified as CID1 per NFPA 820, with NFPA 820 - Figure A.4.2(c) used as a reference, would this stub up be treated like a vent (3' div 1 radius, 5' div 2 radius) or a hatch (3' wide x 18" high div 2 classification)
I appreciate any help, or direction to additional reference material!
Thanks,
C
