I posted the following in the General Discussion Area which was probably a mistake:

An existing aerial feeder consists of 800 feet of 6AWG and 100 feet
of 10AWG. It's 120 volts, single phase. 15amp. load. What is the
proper method of determining voltage drop when there are two
different size conductors on the same feeder.
I use VD=2KLI/CM

Wouldn't it be a matter of figuring and adding the two sections? What is the load PF?

Bjarney-

Yes, that is correct. Bob gave me that exact answer. I guess I thought it was more difficult than that.
