Step 2 - Select the conductor to comply with Sections 110-14(c), 210-19(a), 215-2, and 230-42 (a). Sections 210-19(a), 215-2 and 230-42(a) required the conductor to be sized no less than 100% of the noncontinuous load, plus 125% of the continuous load. Code Change Summary: A new Table was added in Article 240. For a great many code cycles, the standard sizes of fuses and fixed-trip circuit breakers used throughout the NEC were listed in paragraph form in section 240.6 (A). In the 2017 NEC, the paragraph was turned into new Table 240.6 (A).

Article 242 is entirely new with the 2020 NEC. It consists of three Parts: General, Surge-Protective Devices (SPDs) 1000V or less, and SPDs over 1,000V.

NEC 240.87 is a growing requirement that is spreading across the nation as more states adopt current code. When additional compliance of NEC Articles 700 and 701 come into scope, compliance of 240.87 becomes even more complicated.

This is easier to read and just makes sense. 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).

Integer sed aliquet ante. Article 240 provides the requirements for selecting and installing overcurrent protection devices (OCPDs). Depending on your application, other Articles may apply (see Other Articles below). An overcurrent exists when current exceeds the rating of conductors or equipment. It can result from overload, short circuit, or ground fault. Code Basics Art. 240: Overcurrent Protection Protecting circuits and equipment from overcurrent from overcurrent involves more than simply selecting a fuse or breaker from a table Art. 240, which is divided into seven parts, provides the requirements for selecting and installing overcurrent protection devices (OCPDs) (Fig. 1).
