how many wires in a cable for a 220v-230v single phase?

is it 3 total: hot, hot, ground

or 4 total: hot, hot, common, ground  




and 3 phase:

is it: hot, hot, hot, common, ground

uhhh, thats for 110v I believe.

If you ONLY need 220/230 sngl phase ... hot,hot,ground
If you need 220/230 sngl phase AND 120 volt ... hot,hot,neutral,ground (120=hot,neutral,+grnd)
If you ONLY need 220/230 - 3 phase ... hot,hot,hot,ground (don't need neutral for straight 3 phase)
BUT ... if you want 3 phase AND 120/220 single phase circuits ... hot,hot,hot,neutral,ground.
Needless to say ... Stay safe.
PS... your asking this question kind of brings to mind that, just maybe, you may want to leave this one to a pro. Just a thought.

+1.  Electricity is not rocket science, but it will kill you deader than a hammer if you screw up.

Do a search on "Hubbell General Technical Data" or Hubbell Straight Blade Devices".  You should find a couple of .pdf's that will show how different voltage/amperage power connectors are wired up.  It will also give you the cooresponding NEMA number so you can get the right connector/receptiple at your local HD/Lowe's.

Then get a pro to install it.

Otherwise, give us some warning so we can start your Darwin paperwork.    

Hope this helps.
