We test some Wago 221 connectors to see how much overcurrent they can survive, They sort of testing is a way to determine what the safety margin is, and as a rule of thumb things should handle at least twice their rated specifications, at least for a short time. Can these connectors do that?
Links to a previous videos where I cover the test setup and methods in detail:

This test is one of a series of undercurrent tests of cables in various situations ranging from a cable embedded within insulation in a 2x4 framed wall to a simple exposed 14/2 cable. You can see the other videos via this playlist:
