[TowerTalk] pull lubricant

[Dick Green WC1M]

All three of my conduits are schedule 80. I had a contractor do the job, and
the pros use schedule 80 for buried electrical service. One of my conduits
does carry 220VAC (only) but I guess the contractor had no idea what would
be in the other two conduits, and used what was familiar -- schedule 80. I'm
glad he did. I'm sure it was a lot more expensive than schedule 40 14 years
ago, but when I look at the invoice today it doesn't seem all that expensive
:-)

a related conduit question -

I noticed when checking out conduit at HD that the sch 80 sweeps are a 
larger radius than sch 40 at least in the 2 and 3 inch sizes they had 
laying around.  So using sch 80 sweeps seems like a good idea for 
coax/hardline runs except there will be a inside diameter small step at 
the coupling to sch 40 pipe (I don't want to pay for lots of sch 80 pipe).

Any experience with mixed sch 40 conduit/sch 80 sweeps and pulling hardline?

PS: PG&E (Calif) requires sch 80 in and out of the ground but sch 40 is 
ok buried for service entrance, they made it work for 500mcm pulls at my 
shop.
