USCG Exam PracticeElectrical safety and general safety
Electrical equipment installed in a location exposed to seas must be which of the following?
- A. Explosion-proof and grounded
- ✓ Waterproof, watertight, or enclosed in a watertight housingCorrect
- C. Intrinsically safe and corrosion-resistant

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