Re: ground question here...

["Metlicka Marc" <mystuffs-at-orwell-dot-net> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

terry is right here, if the sub panel is more then 3' away from the main
distribution panel, then it should ""by code" have it's own ground rod.
i really wouldn't use the bare wire fore a neutral either, so you could
always  run a 12\2 into the house and use both of them for N, and use
the bare fore another G between boxes. also now a days the grounds all
go on there own bus and N's all on another, this way if something goes
to ground there is no chance of a cascade of tripped breakers in the
main. this goes for the main dist. panel as well.
