Wire measurement including 2" 90 bend

[dhalleron]

I screwed up on an upgrade from 100 amp to 200 amp resi service quotation. I figured going straight up 10' from the meter like the existing and then the meter locator guy told me he needed the point of attachment to be almost 25' farther away. I should have noticed the window on the second floor addition that the old service drop passed in front of, but oh well.

Anyway, I have some 3/0 wire that will be so close to making the long neutral. I have a 49' piece.

I really don't know how much wire to figure for 90 degree bends and LB's when calculating the wire. Normally I don't care much, but I have a certain amount of wire and want to know if it will reach.

Still don't know how to add a picture. Here's a link with conduit measurements. Will a 49' neutral make this run from the service drop to the main breaker in the basement?

In you photo the 90's will actully shorten the run as they are inside bends, a sweeping 90 cuts across a corner so if you go by your total run you will have a couple inchs left over, so adding your run up:
7'+19'+9'+3' drip loop, and if the run inside to the panel is 3' then it should be about 4.5' to hit the breaker lugs, so total is 42.5 feet.

Thanks.

Duh. I should have thought about how it cuts the corner. I guess I was too busy thinking about my screw up and how much less I am going to make on this little job.

When I was in my teens, I was working on my car trying to figure out why it wouldn't start, I was getting angry and frustrated, my Dad came out of the house and made me put up my tools till I calmed down, later when I went back to it, I went right to the problem, bad set of points.

Stress and frustration can cloud even the best of minds.
