I need to pull 100 feet of service wire...two 2awg...one 4awg
neutral...and one 6awg ground wire through 100 feet of 1 1/2 inch thin
wall. The heaviest I have ever pulled is 12 awg

What's the best way to pull this through...mostly straight run with a
90 degree up/down of about 8 feet at each end.

I have a number of regular fish lines...but is there a "heavy duty"
fish line for this type of work ?

Any other pointers...tips....will be really appreciated !

Don't use the frontend loader! :) (In olden days did support/service
of line of online coal analyzers at mines/prep plants. In one new
installation they used the large front end loader to pull the high
voltage coax. It came and worked (for about a month). When replaced,
discovered the friction had been so great had actually melted through
the corners of the elbows and sawed them right through!)

Anyway, to your question(s)...

Have you done the capacity calculation? Probably ok, but might be
close? Bigger conduit -- easier pull at not much more cost...

Lube, lube, lube, ...

Sweep elbows, not sharp corners. To have any chance of pulling by
hand will almost certainly need to have access box at second corner
then re-feed rather than pull two corners at once...

Not tried a pull of that distance of that size personally, but suspect
it won't be easy...Longest I've had to actually pull myself has been
on order of 10-ft or so before getting it underground -- but even that
isn't w/o effort w stuff as stiff as 2.

Good luck...
