I'm hoping to get some new audio/video equipment soon. The circuit where
it's going to plug in is an old one in that occasionally overloads, and also
has no ground connection. Last year, we added on to the house and put in
brand new electrical service (new 200 amp box). There are 3 or 4 breakers
in the new box that are not hooked up to anything - it appears they are
unused. I would like to use one of these unused circuits to hook up to a
new outlet for my audio/video equipment. I assume that it's just a matter
of stringing the appropriate guage wire from the circuit breaker to the
outlet. Is there anything else that I should be concerned about?
Thanks in advance.
lot of abuse before there is a problem. There are many code requirements as
to spacing of supports, how the cable must be run, grounded, and on and on
and on and on. You can ignore many of them and get away with it 99 times
out of a 100. It is that 100th time that is the killer.
But there are somethings that done wrong can be catastrophic. A previous
owner of my house put in a new circuit. For some reason he moved a breaker
when he did it. Most of the time that doesn't matter, but the breaker just
happened to be one of two on a multiwire circuit. He could easily have
burnt the house down. Obviously he didn't, but it was just a matter of
luck. If I hadn't actually seen it done, I never would have thought of it
as something to be concerned about; cause it's just so damned stupid that it
could never happen. But, it you have never heard of a multi-wire circuit
you wouldn't think twice about doing it. I am sure there are hundreds of
things like that, but no way I can point them out.
Another consideration is that running a new circuit in existing construction
may not be easy. Your situation might be pretty simple, but in many it is
nearly impossible unless you know the little tricks. Sometimes it actually
is impossible unless you are willing to rip open walls.
If you still feel confident, then good luck!
Such as putting a staple into the cable. Seriously, you
need to get a book of simple electrical repairs and
practices, such as available from Lowes, HD, or a book
store, and study it for a bit. If you system is correct
now, adding a wire for a new circuit as you propose is
simple. The only real concern is to is that the wire size
and breaker size match, the wire is secured well, any
connection are within a box, and the connection are
correctly made. Most of the work is simply cosmetic in
getting the wire strung between two points.

Second, the right knowledge isn't that hard to obtain. Home Depot, Lowes, your
local library, and most bookstores have books that explain how residential
electrical systems work, and how to do simple tasks safely. You can also get

Third, check with your local electrical inspection authority. You may need to
get a building permit, in order to be strictly legal.

I agree with Tim on his three points--and would suggest an easily

electrical wiring projects.

To be on the safe side do us all a favour and hook up the new outlet first
and then power down the whole house (Before the box if possible) and then
hook-up the new circuit breaker. If you haven't done this before it might be

From here it is difficult to know what problems you may come up against.
Do you know the requirement of running wire in an attic? Do you know the

This is a "look over somebody's shoulder a couple times" type of

work but don't annoy them.

Here is what I'd do.
I'd tape off the wires and run a new 14/2 with ground from the
service and connect it to a new grounded receptacle on one end and one
of those unused breakers at the service panel.
Now what's hard about that?
