We have 18A flowing through the circuit so the next higher OCPD rating would be 20A. (B) Feeder Taps. Taps can be made at conductors without overcurrent protection at the tap as noted in section 240.21(B)(1) through (5) below. The provisions of 240.4(B) cannot be applied for tap conductors. (1) Taps Not over 3 m (10 Feet) Long. 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).

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.

Dec 19, 2011 NEC 240.4(G) applies to overcurrent protection for specific applications and sends you to Table 240.4(G) where you find, first in the list, air-

NEC 240.4(B) (2005 edition) allows the next higher standard OCPD rating (above the ampacity of the conductors being protected) to be used for OCPDs that are 800 A or less if the conductor ampacity does not already correspond to a standard OCPD size and if certain other conditions are met (see 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 … 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 … Visit http://www.MikeHolt.com/code to explore our product catalog.
