USCG Exam PracticeBatteries and storage systems
Per 46 CFR §111.15-25, for a large storage battery installation, where must the overcurrent protective devices be located?
- A. Inside the battery room, adjacent to each battery
- B. At the main switchboard, regardless of distance from the battery room
- ✓ Next to, but outside of, the battery roomCorrect
- D. At the battery charger output terminals
Why C is correct
46 CFR §111.15-25(a) specifies that for large storage battery installations, overcurrent protective devices must be next to, but outside of, the battery room. Placing them inside the battery room or at a remote switchboard does not meet this requirement.
