I know there are plenty of Ecad programs out there for small electronics and arduino circuits etc. but is there anything out there for our side of things? A/c stuff (8 pins, start -stop switches, contactors, SSRs etc.) I know you could use a paint program or sketchup or something and just draw a bunch of stuff together on a screen but there is no way to validate it or simulate it or verify it all works. Any suggestions are welcome.
