Between "Wire" and "Label Net" find "Ground" button.

ok...then opens dialog box saying

GND(global node 0)
COM
ABC (in box is 0)

So default set in ABC is 0 which correspond to GND( As GND is node 0)

So where i find EARTH or what should i put into ABC box?

Thanks

You don't have to click on ground symbol and open dialog box...just put it on the workshit. Or you can open dialog box and in ABC type "EARTH" or whatever you like.

As spice is a simulator I don't think that earth is particularly relevant... I assume you mean safety earth as opposed to ground. You could always make your own earth symbol in the editor and save it as a component I guess.

You could use a label (output) and just put the word EARTH in it.

Hi robydream, Then you need the ground symbol! You said in the first post that you knew that the ground symbol was 0V and that you wanted an earth symbol instead.

Attached are pictures of the ground symbol. If that doesn't help either then iether you are missing something, or I am!

Tony.

Hi MiiB I'd rather not! working in IT it becomes second nature to do screen shots of stuff as trying to explain something is often difficult, and a picture says it instantly
