A few days ago I asked a few questions about installing a subpanel in
my garage. I am done with this job. I used 8 gauge THHN wires, 3/4"
conduit, little corner thingys, and ready made bent elbows.

The subpanel is HomeLine. I used a HomeLine 60A breaker on the main
panel (which has all other breakers by Gould), and have the following
breakers on the subpanel:

50A 220V (this is 30A now because I bought 30A by mistake, but I will
replace it with a 50A asap).
20A 220V
20A 110V
20A 110V

I have not yet installed the outlets.

I had a father of my friend visit today, he is a professional
electrician. He okayed my work.

I am going to return my kerosene heater to HD and install a 220V 4.5
kW heater in my garage. Also, one of the reasons why I did all this is
that I have a 2.2HP
compressor (harbr freight), which tripped the breaker when it ran with
other tools. Now it will have its own circuit.

I might install an air line from the garage toi the basement, to have
air in my basement workshop. It should not be difficult.

With a 60A breaker, your hot wires should be 6 gauge, not 8. You said
previously that you had already bought the #6 wire, so hopefully you just
mistyped it above.

Other than that, it sounds OK.

I like using 1/2" copper pipe for compressed air, although galvanized is
traditional. Don't use PVC for compressed air.

Best regards,

Good advice Bob on not using PVC for air! I have seen that done in an
industrial setting many times and when I questioned it the maintenance dept.
they would point to the pressure rating on the pipe and claim it to be OK.
What they fail to realize is their are surges in air that make it rise
substantially. Also, compressors tend to pass oil, not to mention the warmth
from compression, which degrades the pipe. I saw a few of them blow,
scattering plastic everywhere. Not to mention the holes in the wall. I saw
another situation where there was a plastic coupling at the compressor. A
maintenance worker backed into it and it broke. The air force him into some
metal framework where he took 90 or so stitches in his head!!!





Thanks for some good stories. I will not use PVC.

My main question now is, is there "plumbing" for permanent air lines
comparable to electrical equipment. Like permanent air outlet boxes,
conduit (to enclose lines), that sort of stuff. My objective is to not
have it look like it is all jury rigged, be reliable and safe etc. I
have a kid who likes to hang around my workshop, so, I want air lines
to be as safe as electrical.

Sure there is. Service stations have piped connections for compressors
located elsewhere.
(air pumps at the gas pumps, on the wall, etc. I don't know if it is
special piping or just plain metal piping.
