On most modern molded-case circuit breakers, the ampere rating is normally marked right on the operating handle or immediately on the front face (escutcheon) near the handle , not on the back or bottom.

Quick Scoop

  • The ampere rating (like 15, 20, 30 A) is:
    • Usually printed, stamped, or molded on the breaker handle itself.
* Or placed on the front label/escutcheon directly adjacent to the handle.
  • You should be able to read the value with the panel cover off, without removing or disconnecting the breaker.

Why it’s there

  • Code and listing requirements specify that breakers of 100 A and below must have their current rating visible on the handle or front area, so inspectors and users can quickly identify rating without tools.
  • This placement reduces mistakes when matching breakers to conductor sizes and loads, since the visible number on the handle is the one everyone references in the field.

TL;DR: For exam-style questions like “Where is the ampere rating normally marked on circuit breakers?”, the intended answer is: On the handle or front (escutcheon) of the breaker where it is plainly visible.
