    Here is one method suggested to test breakers.

    There is no reasonable way to field test the long time trip rating of small thermal magnetic breakers. Simply loading them up to 200% is not accurate.

    Among other things, the trip curves are based on a specific ambient temperature, if you conduct the test at any other temp, the tripping time will be affected and there are no published adjustment factors.
    Just because you can, doesn't mean you should.

    I thought home depot or Lowes was selling new FPE breakers. I don't know who makes them but they are something like $20 each for sp breakers

    It's possible, but I never shop for Fire Producing Equipment breakers so I wouldn't notice them even if they did sell them.

    US retailers sell replacement Stab-loc breakers manufactured in China for Connecticut Electric. You are not going to find any new breakers manufactured by Federal Pacific Electric unless they are really old new stock. In Canada Schneider Electric (owner of Square D) markets the Stab-loc design and it is one of the most commonly used today.

    Publishing a trip curve that is valid over an ambient temperature interval should have the effect of thickening the band on the graph.

    Or, if the temperature coefficient of the breaker is known the curve could be corrected for other temperatures but this kind of detail is probably rarely published by CB manufacturers.

    I saw this but don't know anything about them.

    Here is a picture of the new FPE breaker from Home Depot. Looks like it is made by UBI???? By the way, this breakers is a dp 30 and runs almost $70.00

    To demonstrate, I place my amp meter on the circuits wire and turned on the micro and toaster. The meter read 29 amps. I waited (~1 minute). Nothing.

    My understanding is that the DP breakers from FPE were the main issue. I don't believe the replacement ones are an issue. I would think that the issues from years ago do not exist in the new breakers.
