- A. Explosion-proof or intrinsically safe
- ✓ Waterproof, watertight, or enclosed in a watertight housingCorrect

Why B is correct
46 CFR §28.350(a) and §28.845(a) require that electrical equipment exposed to weather or seas be waterproof, watertight, or enclosed in a watertight housing. Explosion-proof requirements apply to hazardous areas, not weather-exposed locations generally.
