If on a 220 single phase circuit the neutral and ground wires attach to the same buss bar in the
panel, why are they both needed ????

Thanks

The fussier journeymen in our part of the country prefer to use one
bus bar for grounds, the other for neutrals. Of course, the two busses
are bonded together. Other than looking really spiffy, I don't know of
any electrical advantage. Maybe one of our eminent electrical gurus
can shed some light.

Where there are more than one "ground bar" I use one for grounds &
one for neutrals.......

why? I'm not sure except that's the way I was shown and I was told
that grounds can be doubled up but neutrals cannot.

So by keeping them seperate it tends to enforce that behavior by
treating them as "different".
I guess that makes sense but in any case it works for me and the
wiring looks neater.
