Simple answer, yes .... breakers do wear out if tripped and/or flipped on and off a lot. (some are more resilient to off-on / and-or / being blown where others are not.) Age and wear does play a factor.
Yep! Male and female receptacles/plugs wear out/break too. From electrical engineering 101: LCL or Long Continuous Loads require that conductors/circuits be derated for reliable service in continuous highly loaded conditions. (like what is happening in this case) 50 amps doesn't always mean 50 reliable amps. (2 circuits in this case)
