Some of the “plug in” MCBs are relatively a very loose fit when you consider that some MCB terminal screws need torquing up to 2.8 newton metres.
Needless to say, the screw to this terminal could have been torqued up, unlikely though it was installed before we were told to buy torque screwdrivers, but I bet it was tight.
