An Engineer tests Wago Connectors. Are they any good?

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: Variac and Arc Welder setup as a current source: https://www.youtube.com/watch?v=9vkMeyAx7o4&t=115s Why we use current (not voltage) sources to test how much current capacity: https://www.youtube.com/watch?v=9vkMeyAx7o4&t=647s 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.
