Update: The Siemans breaker was installed earlier last week. The fit was more "firm" than the GE. We're watching it closely. At 31A/235v it still gets warm on a 1.5 hour charge, but not as hot as the GE breaker. We noticed the 8g wires to the outlet a foot or more from the breaker also get warm after a while. This worries me but that might be somewhat normal?
That said, the original breaker had moments when it was only slightly warm but on other charge cycles was quite hot. The behavior was random. It might still be. More than likely will be replacing the outlet and the box around it next, Only dedicated electrical supply outlets carry Hubble or Bryant 14-50's. Forget Home Depot, Lowes or Mennards for those. Only $10 crap (which weigh basically nothing) are available in the big box stores.
