Table 240.6(A).
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). This is easier to read and just makes sense. Be careful not to forget about the additional standard ampere ratings for fuses mentioned in the parent text of the section.
Below is a preview of Article 240. See the actual NEC® text at NFPA.ORG for the complete code section. Once there, click on their link to free access to the 2017 NEC® edition of NFPA 70.
2014 Code Language:
240.6(A) Fuses and Fixed-Trip Circuit Breakers. The standard ampere ratings for fuses and inverse time circuit breakers shall be considered 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000, 5000, and 6000 amperes. Additional standard ampere ratings for fuses shall be 1, 3, 6, 10, and 601. The use of fuses and inverse time circuit breakers with nonstandard ampere ratings shall be permitted.
2017 Code Language:
