    Default Arc Fault Breaker Temp

    Gentlemen and Ladies,

    Question. At what temperature would you consider an arc fault breaker to be 'too hot' indicating a potential concern? Measured several today that were all around 115*. Other, non arc faults, were all room temperature, 76-77*. I typically find them to them several degrees above non arc faults but not this much warmer.

    Thanks

    The temperature rating should be on the breaker, to my knowledge that should be about 40 celcius/104 fahrenheit.

    Per the attached from Eaton (a manufacturer of over-current devises, including arc faults), between 80 - 120 F is normal, with higher temps (187 F given as example) still meeting UL listing for the devise.
