One More Question Re House Circuit Breakers, Please ?
another device thats designed to fail in a benign way are cal stat
thermostats. they are designed to go lower than their design
temperature as they age.
in 30 years of using them for my job i have only ever seen one fail
hot, while i have replaced a couple hundred that failed low...........
for liability reasons no one wants something that when it ages its
dangerous
