84 b Ratio in brackets corresponds to the molar ratio of HBA : HBD. c Calculated as the wt% of … Similar to feeder taps, covered in the last issue, transformer secondary conductors can be every bit as confusing. Let's take a closer look at 240.21(C) to help clear up any misconceptions. Basic rules As with feeder taps, you can't use the rule provided in 240.4(B) for any transformer secondary conductor. Normally, you can use the next highest overcurrent protective device (OCPD) above the Power up convenience and control.

Current list of allowable means in section 240.87 of the 2017 NEC and considerations for their use Method Change from 2014 NEC Eaton available solution Considerations New: 240.87 Non-Instantaneous Trip. this relocation will harmonize the ampacity correction factors for various ambient temperatures between the NEC and the CEC, consolidate the ampacity correction and adjustment factors into a single section [310.15(B)], switching with local status indicator per CEC Article 240.87(B). K. Fully equip unused spaces for future devices, including manufacturer required connections and mounting hardware.

(A) Documentation. 240.87 Arc Energy Reduction. Where the highest continuous current trip setting for which the actual overcurrent device installed in a circuit breaker is rated or can be adjusted is 1200 A or higher, 240.87(A) and (B) shall apply.

240.87 as an "Energy-reducing maintenance switching with local status indicator".

Breakers rated 1200 – Amp or higher must utilize one of the methods of reducing arc energy, and documentation shall be provided showing that the method chosen to reduce the clearing time is set to operate at a level below the available arcing current. Citing CEC 240.87 as a reference, if a circuit breaker can be set to trip at 1,200 A or higher, it is only fitting that the fault clearing time must be reduced to impose safety.
