I have indeed accidently tested a breaker by shorting it that led to the discovery my FPE is a fire hazard. Breakers are by description designed to be tripped.
In the office machine industry technicians are trained from day 1 to TEST all safety protection devices by overloading or over stressing them to CONFIRM they work as designed. Safety switches fail sometimres and a critical one can cause a fire or injury.. bryyer the tech finds and fixes it than a building burns down:( The only tst device I can think of that isnt supposed to be tested is a thermal fuse since they are one shot devices....
I have no doubt there are circuit breaker test devices.
If I get some links on these things will you quit being a PIA?
yeah NEW faucets are designed to leak under very high pressure, so a frozen pipe doesnt mean a ruptured pipe, faucets leaks instead, its actually a good idea.when things thaw no harm done. thats a new federal law.
