Please log in for more thread options Can anybody point me towards a circuit diagram/plan. I am looking for a design where I can operate a relay by sensing mains (240v ac) power being switched on in a cable. No metalic contact is to be made with the mains cable (ie cut into it). I can wrap a wire round or along it. Thanks | ||||||||||||||||
