I have started to document the electrical system in a custom machine that we own. I'm using TinyCad for the schematic and that's working OK. I also want to create wiring diagrams to represent the routing of wires, which DIN rail they equipment they are connected to is on, etc.
I'm new to ALL of this. I'm trying to figure out why DIN rail mounted terminal blocks don't seem to be represented on the diagrams I see when I google. To be clear, I'm referring to terminal blocks like this:
- Is there a standard symbol used to represent a terminal block?
- Is there a reason why I don't see terminal connections depicted in wiring diagrams?
