Just use the side terminals. 2017-10-04 Section 240.4(D)(7) in the NEC ® tells us that, in general, the maximum overcurrent protection permitted for a 10 AWG copper conductor is ___ amperes. one, unless listed for more (2017 NEC: 110.3(B)) The maximum number of Type NM cables that can be inserted into a connector is ___.

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. 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: 240.4(E) through (G), the overcurrent protection shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG copper; or 15 amperes for 12 AWG and 25 amoeres for 10 AWG aluminum after any correction. factors Tor ambient temperature and number of conductors have been applied.

The rating of the overcurrent device must be considered when sizing a conductor. In accordance with 240.4 in the National Electrical Code (NEC), conductors (other than flexible cords, flexible cables and fixture wires) shall be protected against overcurrent in accordance with their ampacities specified in 310.15, unless otherwise permitted or required in 240.4(A) through (G).

NEC 240.4(D) Small Conductors. Unless specifically permitted in 240.4(E) or (G), the overcurrent protection shall not exceed that required by (D)(1) through (D)(7) after any correction factors for ambient temperature and number of conductors have been applied.

According to NEC table 310.16 the ampacity of No. 14 AWG is 20A at 75'C. 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.
