Yesterday on an inspection, I came across an Square D HID breaker.

The breaker was not "imprinted" with the usual data (HID, temp, VAC, etc.).

Molded into the case was the Square D logo and a couple of other miscellaneous numbers that did include "220" which corresponds to a specific line.

On the side was a "sticker" that had the part number, which of course correctly corresponded to the QO-HID line.

Normally, I can ID a breaker (a newer breaker) from the panel without removing the cover. Once this breaker is installed, it will be imposssible to determine rating data.

Now for the question, this is the first time I've come across a new breaker without very much data imprinted on the "face" of the casing, is this common?
