Your example of the PAM-1 Relay lends credence to my diligence in always isolating all unused conductors whenever I connect up ANYTHING with multiple flying leads. Others have said that I'm probably just wasting my time, but as an example, I've come across situations where 3-pole dry-contact leads had one of the leads left unconnected, which ended up causing either an unintended output, a short circuit, or an earth-fault immediately or even years later. I am surprised that the PAM-1 Relay doesn't have complete isolation between its high-power AC coil and its low-power DC coil. Thanks for the tip!Anonymoushttps://www.blogger.com/profile/02262268013700787462noreply@blogger.com
