THE SHORT ANSWER
DOE severe-weather guidance recommends evaluating enclosure ratings for high winds, driven rain and marine exposure, including NEMA 4X in hurricane-prone applications. [1]
Identify each enclosure location
Record exposure to direct rain, roof runoff, flooding, sprinklers, salt air, sun and wind. A shaded wall and an open coastal elevation are different environments.
Read the complete listing
Ask the design professional to document the selected enclosure rating and compatible hubs, fittings, drains and door hardware. A high cabinet rating can be undermined by improper entries.
Preserve service access
Choose locations that remain safely reachable without blocking required clearances or utility access. Do not hide equipment where leaks or corrosion cannot be observed.
Inspect after severe weather
From a safe location, document door damage, water marks, corrosion or alerts. Do not open wet or energized equipment; follow manufacturer shutdown instructions and request service.
