If, by "multiple pulls" it means feeding the wire through each section of
conduit separately, then connecting the conduit, it could be they are
worried about catching the wire on the sharpish ends of the conduit and
nicking it. With the conduit completely assembled, the ends are in the
connectors and there shouldn't be any exposed to catch on the wire.
If it where me I would put a pull box about half way between both ends and
do a double push from that point to each end. If that doesn't work out then
you need a wire puller that could be rented cheap enough.
Use 1" conduit. It will be easier to pull or push the wires in. If you are
going to be installing the wires yourself install a "C" condulet (Maybe 2)
about halfway into the run. It will make it easier for one person to
install the wires.
I suggest a # 8 for the ground conductor. It is all you need and it will
take up less room in the conduit.
Install the conduit first and then install the wires. You will be dealing
with too much if you try to do it all at once.
Fishing should be possible, I did that myself with 3/4" IMC. Only 180
degrees worth of turns though.
The ground wire can be #8, but I'd keep the neutral the same as the
mains, since it is possible to fully load one half of the service,
requiring the neutral to carry full load.
You can get wire pulling lube at the store, it makes pulling easier.
Your kidding about pushing the wire........ HA HA HA...
You will be so frustrated before you done that screaming will seem not
Install the conduit, strap it down. Now if you have a fish tape use it if
not get a plastic bag from the SO and tie some light string around the
middle of it. I use nylon. Suck the baggie though the conduit using your
vacuum. Now pull a small rope through the conduit.
I highly suggest that you pull a ground wire. Relying on conduit is not a
good idea. Connectors and coupling do get loose and then you have no ground.
Put a loop on the end of the rope using tape. Double it back on itself
and/or twine the strands into the rode, we call it weaving. SMALL as
possible for this loop/head.
Now the wire, strip all of the conductors back starting with 4 inches and
stair stepping to 8 inches. Bend over 4-5 strands of each wire and cut off
the rest. Use the 4-5 strands to lay in the wire to your loop. Now tape up
the "head" of the wire leaving the exposed looped over wire. Helps believe
Your all set to pull in the conductors.
If you do not have any wire lube, you can use IVORY soap. NOTE SOAP not
Slime the head and have some one pull gently until the head is completely in
the pipe. Keep slack on the wire and allow the rope to pull the wire
thorough. Slimeing with each pull.
Comment on the #8's was right on reducing the neutral for the load is quite
Nobody's mentioned it, but the NEC requires that the conduit fill be
reduced for each bend.
What this meant in my case, running 210 feet underground betwixt barn
and garage through four bends, was that my conduit fill allowance was
reduced to total about 16% of the cross-sectional area of the conduit
rather than the 40% fill allowed for straight runs.
