However, NEC 240.4(D)(2) state's that 14 AWG must be protected at 15A. According to 240.4(B) the next higher standard OCPD is permitted to be used under certain conditions. We have 18A flowing through the circuit so the next higher OCPD rating would be 20A.

The ungrounded and grounded circuit conductors of each multiwire branch circuit shall be grouped by cable ties or similar means in at least one location within the panelboard or other point of origination.

2018-07-24 ___ NEC 240.4 – Conductors shall be protected against overcurrent in accordance with their ampacities specified in Table 310.15(B)(16) and 240.4(D). The maximum overcurrent current device (breaker/fuse) for most dwelling unit branch circuits is: Fuse/Circuit Breaker Copper (awg) Aluminum (awg) 2018-05-30 This section consists of NEC free online practice tests. These tests helps in preparing for Journeyman and Master electrician License exams. NEC 240.4 requires the branch circuit, feeder, and service conductors to be protected against overcurrent in accordance with their ampacities as specified in 310.15. Section 240.4(A) through (G) contains rules that modify the general requirement and permit conductors to be protected in a manner other than their ampacities from 310.15, including: The branch-circuit conductors are sized per NEC 430.24, which result in 8.9A or 14 AWG Cu per NEC Table 310.15(B)(16) and NEC 240.4(D). The branch-circuit overcurrent protective device is sized at 15 A per NEC 430.53(A).

Notify me of follow-up comments What’s on their mind is a different table, NEC 240.4(D), which places artificial limits on #14, #12 and #10 wires, to limit them to 15A, 20A and 30A regardless of tables or thermal calcs. Their logic is “heck, you can’t run these wires at thermal limits anyway, so why do they need to be -2?” Se hela listan på ecmweb.com You must protect conductors against overcurrent, based on the ampacities in 310.15. As you might expect, this rule has exceptions. First, it doesn't pertain to flexible cords, flexible cables, or fixture wires. Second, 240.4, Parts A through G, provides an extensive list of “otherwise permitted” items.

A: In the 2011 NEC, only applications where an instantaneous device was not present were required to provide additional means to reduce arc-fault energy. In 2014, the wording was changed such that a properly adjusted instantaneous device was not included in the list of approved energy-reducing measures.
