FAQ
What conduit sizes does this box accept?
All five hubs are ½-inch NPT threaded. For ¾-inch or larger conduit, use reducing bushings or select a box with appropriately sized hubs.
Is this box suitable for GFCI receptacle installation?
Yes. The 4-inch round form factor and 1.6-inch depth accommodate standard GFCI receptacles. Verify adequate interior space for device wiring and confirm cover compatibility for the specific receptacle type.
Does NEMA 3R rating require a specific cover?
NEMA 3R protection applies to the complete installed assembly. The box requires a weatherproof cover rated for the application (while-in-use or standard) to maintain environmental protection per NEC 406.9.
