First off diy'er so be nice. Just wondering if anyone has any experience with Quinetic switches / receivers? I have an outside security light, installed about three years ago, which is switched on and off via a 2 gang Quinetic switch at my back door. The receiver is fed via an FCU from the lighting ring and situated in a wiska box directly above the light. (There doesn't appear to be any water ingress into the box) When i press one of the switches the RCD in my CU trips, none of the individual mcb's. I thought at first it was just a coincidence but it happens every time I press the switch. Been doing it for three days and does it every time I press the switch. I've switched the receiver off via the fcu it's powered by, still does it. I've disconnected the receiver completely (don't shout, by this point I was losing the plot) still does it. The other gang of the switch which is doing a different receiver works perfectly. If i reconnect the circuit and pair it with a different switch it works fine. I've got someone coming to look but in the meantime my question is how can a wireless switch that effectively isn't connected to anything trip an RCD? Am i missing something blatantly obvious??
