What is the best way to run the feeders from main panel
to subpanel on the outside of the house? The attic install
looks nasty, blown in insulation 12" thick, plus sloping roof.
/argggg..

Plan b:
I can run the lines on the outside wall of the house and the
run would be much shorter in length, about 35 foot.

The main panel is embedded on the outside wall so if
I rip off some drywall on the inside wall, can I run feeders
by drilling a hole in the stucco and install some hardware
there?

Plan c:
Run the wires under the house through the crawl space...
ruh roh.. spiders there

Good selection on the panel box.

My first choice would be the crawlspace, second choice attic, and finally third choice along the outside of the house.

Did you decide on THHN in conduit or a cable assembly? If you run conduit outside the house or in the crawlspace, you will need to make sure your conductors are rated THWN (for wet locations). Almost all THHN is dual-rated THWN, but it is a detail to check. The inside/outside temperature difference allows water to condense into liquid inside the conduit.

Set off a bug bomb in the crawl space before you leave the house for a while...

Dead spiders are less scary.

I analyzed the homestead and the crawlspace is the
ideal choice, I can run less than a 50 foot run and no
awkward cables on the outside. I bought alot of
bug killer chemical and plan to bomb the underneath today
and clean out tommorrow. I'll probably get someone to assist on the install.

Confused. THWN is good for wet, but is THHN also
for wet?

I want to get individual cables and shove them in the gray
PVC pipe and bracket them to the wood framing
underneath.

You don't need to drill drain holes in the PVC for water
build up in pipe runs do you?

Why doesn't the big home centers carry white and green
#2, #4 cables? I see less and less electrical supply stores
here because they home centers are taking over, but they
lack in these esoteric supplies. ?

I also snagged a book on electrical wiring - has pictures

Turn off all gas pilot lights and flames and the dryer if it has a pilot. if you don't want to blow up your house.

No. THHN is not suitable for wet locations, but THWN is. They are two different specifications. The wire you purchase will be labeled for all of the specifications it meets. It is very common for wire to be dual rated THHN and THWN. That simply means it is suitable for use where either THHN or THWN is specified.

I assume you mean individual wires. A cable contains multiple wires (for instance, Romex). When talking individual conductors, they are just referred to as wires. (I know, kitpicky, but it gets confusing when the terms are mixed up.)

No, don't do that.

Wires that size are rarely colored other than black. Just reidentify your neutral conductor with white electrical tape on each end (don't just use any white tape you find, use electrical tape) and your ground with green.

Wiring Simplified is a good book...about $6, if you want another.

24 bug foggers in the crawlspace later and three 500w
shop lights, I went down to check it out. uggg... not much
room to crawl, I feel like a snake belly wiggling to move
down there simultaneously using a broom to sweep away
old spidy webs. 1/3 of the floor plan isn't so bad as other
people were down here a few years back, but off yonder
it's pretty nasty with old webs. Basically, I cleared
50% of the area I need to be in.

Unsure about the uncharted territory, I snagged 12 more
foggers and concentrated them in that sector to ensure
bug batterment.

Knocked down another wall section to verify if the flex
cable can run from source to destination, looks hopeful
so far.

[looks around] "here kid, here's $50 to run the pipe under the house .. shhh ...."

How do electricians do this job daily, attic and crawlspaces
exploration?

Don't watch the movie Starship Troopers before you
go in these areas, also haunted house movies aren't
cool. Even un-cooler is if your spouse unplugs those
three 500w lights down there

Exclamation

The six o'clock news often has an item about someone who put 24 bug bombs in the house. The propellant from this many bombs DOES produce an explosive concentration, and the result is usually one wall of the house being blown off.


I am glad you appear to be coming to the end of your project. I must say, we put a man on the moon in less time and with less trouble! What's wrong with a simple boom box? I can see no good outcome from the system your are building. If you have any neighbors within several hundred yards, they will have the cops down on you the first time you light it off.

I saw Mythbusters on this issue, it was very difficult for
them to get an explosion when doing the bug bomb test.

I am glad you appear to be coming to the end of your project.

I started the audio quest years ago and it's still going.
The plan is finally coming together and setting up the
homestead to support it is phase 1 of the project. Phase
2 is to build the monster. Driver cost is ~$25,000 for
the four tower line array, so that explains the 'years' to
completion. {then there is the cost of the electronics I need, ie amps, sources, projector, etc.} .. arg ..

I already had cops here the first time I fired up the
baby system in the garage. ... a sign of success.

The point of this sound system is to have my own
Ozzfest at home.
