Terminals connecting to themselves despite jumper

mratering — Tue, 28 Jan 2025 14:15:52 GMT

I'm building a simple circuit - a transformer feeds terminals that are jumpered together, distributing power to various circuit breakers and fuses. The terminals are single level screw terminals that may have up to two wires per terminal.

I've tried this two ways and neither do what I'm looking for.

With X1 I put terminal symbols on every branch. Despite the jumper i still see connections in the terminal strip editor between X1 terminals as if there is an actual jumper wire between them consuming one of the two screw connections.

With X4 I put a single terminal symbol, hoping that AutoCAD Electrical would see all the branches below. It did not.

The drawing:

X1 Connections:

X4 Connections:

How do I accomplish this without consuming my terminal connections with the jumper?

This looks like you have assigned a jumper, using aejumper or TSE, AND have connected the terminal using a wire layer on the schematic, forgive me if I have misinterpreted.

You cannot do this and should use one of the following methods

1) you can use the terminal jumper, if you want to connect these schematically this must be a none wire layer (eg. layer 0)

2) do not assign the terminal jumper, connect the terminal schematically using a wiretype with the text 'JUMPER' in the layer name, anything on a wirelayer with JUMPER in will be excluded from all annotation

you should not use the above in combination, you will get issues with wiring loops that AutoCAD will not be able to resolve

Worked perfectly, thank you. Could you point me to where i might have found this in the documentation so i can do a better job searching next time?

something in the help here about the wire layer

https://help.autodesk.com/view/ACAD_E/2024/ENU/?guid=GUID-FF4EBBDF-3143-4C3C-A999-5538F8361196

sorry, I'm not sure if there is anything about the combination issue or use of none wire layer to represent aejumpers.

Nothing beats a proper training 😂. But you really should just ask here.

AcadE and terminals is a big pain in...

Are you just connecting to one side of the terminals like it shows in the TSE?

Or is the first X1 terminal one side, and the second one the other side of the same terminal?

The connection in TSE is generally correct. For my application the Internal and External are swapped to get the block to make the footprint correctly but practically that doesnt seem to be a problem.

Now I'm encountering a slightly different issue. The terminal editor is seeing the connection to VPN706 but not to ENET1716. Jumper wires circled in red. I'm not sure how to get two wires on the same terminal otherwise.

is this a wire sequencing issue, the connecting wire is going from 101 to VPN706 to ENET716?

This is exactly what is solved so very nicely in other ECAD/CAE programs. You can draw each of the "holes" in the terminal as a separate symbol, and it will automatically be interpreted properly (Automatic saddle jumper etc!)
AcadE's handling of terminals is a shame IMHO (and also many others,)
