wiring diagram

wiring diagram

wiring diagram

(OP)
I'm drawing a wiring diagram to show how the mains get distributed inside our enclosure (terminal strips, fuse blocks, ground lugs, switches, etc.).  I've seen lots of variations on drawings like this, so what are the standards?  What is your favorite technique?  Does anybody have an example drawing that they would like to share?  

Thanks,

John D
 

RE: wiring diagram

Within any standard, there's often some flexibility in how you arrange the components or elements within the drawing.

I think that it's helpful if the schematic follows the physical arrangement to the extent that it's reasonable to do so.

 

RE: wiring diagram

I worked at a place where the wiring diagrams included fairly accurate pictorial representations of relays, terminal strips, etc., arranged pretty much as they are in the actual box, except that they may be scaled or distorted or spaced apart a bit for clarity.

The objects are connected by two-line representations of each wire, filled with color exactly like the real wires, including two-color wires.  AutoCAD's 'multiline' objects make this slightly less of a pain than drawing seven parallel polylines per wire.

Making a drawing like that look 'clean' takes some extra time, but then much of the wiring can be done by mechanics who are not electricians.
