Default how deep to bury conduit?

I'm trying to find my local/state building code requirement for depth
of placement of conduit that I'd like to run from my basement to my
detached garage, but my city's online resources aren't telling me
exact depth requirements.

Does anyone have a pointer to this New York State building code
requirement? I'd really appreciate it.

If anyone's interested in this kind of a project, Hammerzone shows how
to do it!

And if you are in a city or other local gov't jurisdiction (county,
district, parish, etc) they might also have adopted code.

Usually it would be in the electrical code, but perhaps NY considers
that to be part of their building code? (Usually building code is
structure, electrical code is wiring, plumbing code is...)

But yet they don't tell how deep to bury it. Oh well. Sounds like
spam...

I'm in California so it may be different but I had to bury mine 4
feet. It was fun work also, from the pole to my house required a
trench 330 feet long and 4 feet deep.

It's not spam: they CAN'T tell us how deep to bury the conduit
because this requirement varies from area to area. They specifically
say on the website, "As you can see, this trench is thigh-deep, about
24 to 28 inches deep. Local electrical codes will specify the minimum
depth of a buried conduit, so contact your local building department."
The site is edited by a man who lives in northern Ontario, but he
doesn't indicate his own code, wisely as it might be vastly different
from anyone else's.

I'm still trying to get an answer from my own city building code
dept., and I thought that 48" code requirement in Calif. was
interesting (must be for earthquake reasons).

I don't think it's for earthquake but could be wrong.
The requirement for the electrical was at 48" but
I was also allowed to bury my phone cable in the same trench.
The phone cable had to be seperated from the electrical by at least
12" so it sits at 36". This is in a rural area so I would not want to
to bury any less of or my tractor implements would be snagging the
cables.

I do know that if you must cross a cemetery with it you have to be more
precise.

Ha.

I did finally get an answer from my city building code dept. For
circuits up to 20 amps, the conduit must be buried 12" deep. For more
amperage than 20, the conduit must be buried at least 18" deep. Also,
a GFI must be installed on the circuit. This is in western New York.

One thing that I did when I buried an outside line some time ago (and it was
18 inches down here in NJ with an electric and a cable line [cable while I
was at it]) was to put a pressure treated 1x4 on top of the wires so that if
anyone ever dug down they would hit the wood instead of cutting through the
wire. I also laid the wire on a few inches of sand down there for drainage.
This all might have been required (it was about 15 years ago...).

Great suggestion, and I may yet take it even though I plan to run the
cable through the grey PVC pipe. On the other hand, if I'm spending
all that money on the pipe, getting enough 1x4 pt wood for this job
(30 ft worth) might be an unnecessary expense.
