Procurement Notes

Verify that the specific application environment aligns with NEMA 3R requirements, which protect against rain and sleet but are not submersible. Confirm that the absence of pre-drilled knockouts meets wiring entry needs or requires field modification. Ensure mounting hardware is compatible with the wall surface type. Check for any regional compliance certifications required for the installation site.
