I think if you check your house wiring, you will find it is grounded
this way, if you have a house built within the last 30 years or so at
least.

Most likely the existing wire will be used for lighting circuit and a
new line run. For those talking about how "cheap wire is" have you
priced 10-3 w/ground direct burial wire lately? It will take a season
or two to re-establish a nice lawn over the trench also.

Now for the "black tape, etc" comment, do you run two black wires
to/from your wall switches? Since you break the black, this is what
you should do, right? Better check to see all of yours are that way.

I wasn't very clear, the thought was to come from a new 220V breaker.
The problem is the neutral would not have individual insulation, but
would be insulated within the bundle, which in the case of the
neutral, shouldn't make that much difference.

This is enough to indicate you should not be attempting this work. Your
plan does not meet code. Code is there for a good reason. Neutral is a
current carrying line NOT a ground. Oh sure you may say, it is connected to
the ground so it is ground, but NO. That is a common comment from someone
who does not understand that there is a good reason for every part of the
code. If the connection to the ground should become separated, that
:neutral may well be carrying 120V.

Please for your own good, follow the good advice you have been given and
do the job right. In fact I suggest it would be a lot safer if you would
chose to hire a professional to do it for you. Note all those who have
responded to your suggestions and how many have found fault with your ideas.

Look over the usual responses and you will find that most of the time we
agree with good save ideas. That should tell you that your plan is not good
and safe.



Thanks,
