Hi folks, there’s a thread running on a caravan forum I’m on so I thought I’d ask on here where the experts live!
Caravan EHU supplies vary between 6A, 10A and 16A. So one of the chaps who regularly goes abroad where there are 6A supplies gets ticked off with the wife tripping the bollard - usually late at night when there is no-one around to re-set it.
He’s asked if there is anything on the market that would monitor the current being drawn, and open the supply before tripping the bollard breaker.
Seems there is in the USA but nothing caravan specific in the UK.
There’s clearly current sensing breakers available with various disconnection times and sensitivity, I’m guessing it would need some sort of control circuit to stop the contact from chattering as soon as it opened and the current dropped - then it would re-make etc etc
So if anyone’s got any (helpful) ideas it would be great to hear them, he is not going to connect anything himself by the way.
