One that I installed in my brother's RV was 3 watts. That's getting
awfully close to the limit on the bell wire. ANd PHONE wire is
generally 22 guage, not 18 - so NO. You cannot use bell wire to wire a
house for low voltage lighting...

Then use landscape lighting wire or 18-16AMW stranded low voltage alarm
or sound system cable. An alternative is what I do when installing CCTV
cameras. I install a central 12vdc power supply and separate low voltage
cables to each camera. A multi terminal central power supply used for
CCTV cameras would be a good choice. It's not rocket surgery. GEEZ!

Again, he can do whatever he pleases, but landscape lighting wire

proposed he wire up is a Class 1 low voltage circuit and it's

It's not rocket surgery, but that doesn't mean that there aren't
codes that are supposed to be followed. Why do it half-assed
instead of reading the code, using the right materials, and doing
it right? As an example to the practical problems you're left
with, if someday he goes to sell the house, an inspector seeing
phone wire used for low voltage lighting may flag it. Then he
has a problem that he could have easily avoided by doing it right.

I've installed both power and low voltage wiring in homes and businesses
and never failed an inspection. Of course, because I was doing it
professionally, most if not all of my wiring was concealed. All the wire
met code for the circuits carrying low voltage even if it was two pair
phone wire. I wired a lot of systems with beige or gray two pair phone
wire and never had a problem with an inspection. The only consideration
is the amount of current the wires will carry. All of the manufactured
low voltage devices I've installed had a label with the amount of
current each device used. If I installed home made DIY low voltage LED
lights, I'm going to measure the current draw and run low voltage wiring
that will carry the load, even phone wire. You keep making it way too

From my reading of the code, the system you recommended is a Class 1

kept charged with a battery charger to power the LED lights which
would be installed in the house. Clearly phone wire is not code compliant
for that application. May an inspector pass it anyway? Maybe in
some places and maybe not in others. The enforcement level probably
isn't going to be the same in a townhouse in NYC as it is in a small
town in the Midwest
All I'm saying is that there are NEC codes for this type of thing
and in my reading of them, you can't use phone wire. It's not
even clear what phone wire means anymore, as it's usually referred to
today as Cat5. My reading of the code says the minimum allowed is

It's not just a matter of the current the wires will carry. Read Article 725 of NEC on what specific cable types are allowed. It's like saying you can
use any wire for 120V circuits, all that matters is the current carrying capability.
All of the manufactured
It's not complicated to follow code and do it right.
Is it that complicated to use the proper 18 gauge wire? In my
reading of the code, that's the minimum wire size allowed for
what you proposed. Have you read Articles 720, 725?

I've installed thousands of feet of single and multi pair stranded 18
gauge jacketed wiring for all sorts of things. If the equipment I'm
installing calls for it, I will use it. Some cities have their own
version of the NEC. An example is Birmingham where I live which has a
stricter interpretation of the NEC than the county I'm in. I remember
reading something about New York where surge arrester multi outlet
receptacle strips are not allowed. I imagine which planet your on would
make a difference in the type of wiring that's required. ^_^

Believe me, I've always followed the code in whatever jurisdiction I was
working in. Sometimes, a jurisdiction will require wiring that exceeds
what's in the NEC specs. The trick is to know where you are and what
will be accepted. o_O

I didn't say he couldn't do it. I just said that NEC applies to
low voltage circuits run within a house too, and that I have doubts
that using telephone wire to power lights will meet code. Whether it's
DIY or done by an electrician code still applies. If he wants to
ignore that, he's free to do so.
