In a last word on AFDDs… until perhaps the next one, I question some of the answers that cropped up in the comments following the prior video. I also put a Fusebox AFDD to the (not terribly orthodox) test to see if it follows the example of Hager’s device or if it favours Siemens' way of doing things.
To reiterate, I’m not saying Hager as a company, or their wares, are in any way unfit for purpose; I’m merely playing with this equipment to see if it acts in the way I expect it to. It may be my tests and expectations that are out of whack. Nonetheless, last week we saw some tripping with a Siemens model, some non-tripping with a Hager, so let’s see what happens with a third device for whatever that’s worth.
