Under 46 CFR §63.01-3, automatic auxiliary boilers with heat input ratings at or above which threshold must meet the requirements of 46 CFR Part 52 rather than Part 63?
- A. 5,000,000 Btu/hr (1.46 megawatts)
- B. 8,000,000 Btu/hr (2.34 megawatts)
- C. 10,000,000 Btu/hr (2.93 megawatts)
- ✓ 12,500,000 Btu/hr (3.66 megawatts)Correct
Why D is correct
46 CFR §63.01-3(b) states that automatic boilers with heat input ratings of 12,500,000 Btu/hr (3.66 megawatts) and above must meet the requirements of Part 52, and their control systems must meet Part 62. Boilers below that threshold are governed by Part 63 for their automatic controls.
