chuxxsss Posted August 27 Posted August 27 Hi, I have had this shelly for two years but never fitted it to my switchboard. I have a 10A cct breaker single phase. I hook up the VA, VB, and VC plus neutral up. plus A, B, C claps on the active wires required. Light turns on then drops the RCD? 40A RCD fitted. Quote Translate Revert translation?

Members thgoebel Posted August 27 Members Posted August 27 Check the connection of terminal N of the Shelly with neutral! Most likely, you‘ve made a connection with neutral BEFORE the RCD (if VA - VC are connected BEYOND the RCD) or vice versa... Quote Translate Revert translation?

chuxxsss Posted August 27 Author Posted August 27 Will check that in the morning. I mat have put the VA-VC after the RCD. Quote Translate Revert translation? English (American) Finnish French German Italian Portuguese (European) Spanish
Members thgoebel Posted August 27 Members Posted August 27 In this case, the neutral must be connected behind the RCD also. Quote Translate Revert translation? English (American) Finnish French German Italian Portuguese (European) Spanish
chuxxsss Posted August 28 Author Posted August 28 You where correct, both the Active and neutral were the problem with the RCD CB earth leakage. My system is very complex. The system has Solar plus solar inverter, generator input with another inverter and battery system, and there is main power too. Now I have lost how to connect to the WiFi. Plus I need to attach to HA too. Quote Translate Revert translation? English (American) Finnish French German Italian Portuguese (European) Spanish
