You are right about the 240v being, essentially, two 120v lines.
?Unlike
120V, which has a Hot, Common and Ground, the 240 has (or can run on) 2
Hot and a Ground/Common. ...

To clarify for OP what could be misinterpreted given it appears little
or
no familiarity exists...240V has _only_ two 120V 'hots' and an
associated
ground, _no_ neutral.

I'm sorry MS-Outlook6 does such a poor job of formatting my reply. I typed
after
the dashes.




Too much in your message(s) to really make meaningful/rational
comments.

So please get some more learning.

Also be aware that the RV power you mention is probably 30 or 50 amp
power. Sure it is 240 volt? And too small for the shop enviorment you
mention.

I just went and looked at it with a flashlight--125v, 30-Amps, "for
Travel-trailer
use only". The plug shape made me think it was 220...
Maybe the line would be suitable for a dedicated DC. I need to learn more
about that outlet.



Where and how 240 volts is sourced to the consumer, has been mentioned
here, but the details that transform the high voltage on the power
pole or in the power vault that is near you property line is more
complex than what has been mentioned here.

Yes, I know little more than that I have a 3 year old (due to hail damage)
200 amp service
and a 220 with 50 amp breakers, which was used for welding (which I assume
suggests
a certain level of integrity).



If you add a power (sub)panel that is sourced from your service panel
remember that are limitations in the code. The neutral and the ground
need to be separate and not connected circuits.

Bob, I had not thought of adding a subpanel. I will need to learn more
about the implications of that.
Thank you for your reply. -Bil.
