New wylex mini RCBO
Former Community Member
I can’t help but notice how small these are, but where has the earth tag gone? How do these devices detect earth?
I’ve notice a tiny metallic strip on the back and front of the breaker but the one on the back doesn’t make any contact with the board as the din rail in wylex boards actually have a groove.
There are reports whereby the new AFDD versions of these devices are causing adjacent devices to trip when the RCD conponant of the device connected to the faulty circuit is triggered by a fault. Cause not yet known
The MEM RCD pods that clip onto the MCBs to convert them to RCBOs have no real physical connection, the pod just sits on top of the MCB but can fire the MCB off as required.
I presume the MEM RCD pod uses a magnetic pulse to fire the MCB off and have often wondered if it could possibly fire an adjoining MCB off as well as the intended target?
