FREE AIR—ALLOWABLE AMPACITIES OF CONDUCTORS * Note for pages 1 and 2 above: Unless permitted in NEC 240.4(E) or 240.4(G), the overcurrent protection shall not exceed for copper: - 15 amperes for 14 AWG - 20 amperes for 12 AWG - 30 amperes for 10 AWG Code reference: NEC 240.4(G), Article 440 Parts III & IV . Answer: No. For A/C installations, the small conductor rules in NEC 240.4(D) do not apply. NEC Table 240.4(G) has specific conductor applications for Air Conditioning equipment.

___ NEC 240.24(D) & (E) – Overcurrent devices (breakers/fuses) shall not be located in bathrooms or clothes closets. ___ NEC 240.4 – Conductors shall be 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 As per NEC 240.4(F), the maximum rating of the overcurrent device allowed on the primary of the transformer that will also provide overcurrent protection for the Aug 4, 2016 2017 NTT, Inc. Where to Keep Abreast of the Latest NEC Information 240.4 specifies the overcurrent protection requirements for conductors. May 8, 2015 NEC® 240.4(B) allows the next higher standard overcurrent protective device rating (above the ampacity of the conductors being protected) to Article 430 of the NEC details motor branch circuit requirements for short circuit and higher standard size but not beyond that allowed by NEC 240.4B. 70 (NEC) Table 310.15(B)(16) per the 2017 NEC or 310.16 per the 2020 NEC when utilizing the user selected conditions of use.

Mike Holt Enterprises offers comprehensive electrical exam prep materials delivered in 240.4(F) verifies that the primary overcurrent device does not protect the secondary conductors in most cases. 3.) NEC 240.21 does not “undo” any of the overcurrent protection requirements of 240.4, it just moves the overcurrent device location from where the conductors receive their supply to a point further downstream. Note: NEC 240.4(C) Where the over current device is rated over 800 amperes, the ampacity of the conductors it protects shall be equal to or greater than the rating of the overcurrent device defined in 240.6. Once there, click on their link to free access to the 2017 NEC edition of NFPA 70. 2014 Code Language: 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.
