What is ansi 63 in circuit breaker wiring circuit

A very specific question!

ANSI 63 is a standard for the marking and identification of circuit breakers in North America, specifically in the United States and Canada. It is published by the American National Standards Institute (ANSI) and is also known as the "ANSI C37.23-1976" standard.

In the context of circuit breaker wiring, ANSI 63 refers to the marking and labeling requirements for circuit breakers, including the type of marking, the information to be marked, and the location of the marking.

Here are some key aspects of ANSI 63:

  1. Marking location: The marking must be located on the circuit breaker's nameplate or on a label attached to the breaker.
  2. Information to be marked: The marking must include the following information:
    • The manufacturer's name or trademark
    • The circuit breaker's type (e.g., fuseless, fuse-type, or electronic)
    • The voltage rating
    • The current rating
    • The interrupting rating (e.g., amperage and voltage)
    • The arc-quenching rating (if applicable)
  3. Marking style: The marking must be in a clear, legible, and permanent manner, using a durable material such as metal or plastic.
  4. Additional requirements: The standard also specifies requirements for the size and color of the marking, as well as the location of any additional information, such as the breaker's serial number or date of manufacture.

By following ANSI 63, circuit breaker manufacturers can ensure that their products are properly marked and identified, making it easier for users to understand the breaker's capabilities and limitations.
