I need to add a piece of 3/4inch rigid conduit between a section of conduit that ends at a distance of 5 ft. from the wall and an outlet box that is located 4 ft. up the wall. I will thread the new piece before bending it. The length of the conduit will need to be
a.8ft and 4inc b.8ft and 8inc
c.9ft and 10 inc d.9ft and 4inc
Answer Normally I don't answer homework type questions, but since you are in the military, I will make an exception. 1=a 1/2" hand bender is a 5" deduction, 3/4" hand bender is 6" and 1" hand bender is 8". Now you cannot put 3/4" rigid in a 3/4" bender, it goes in a 1" bender. So that would make the answer to 3=c. 1" of threads goes into the coupling and into the outlet box [more or less]. Close enough for government work, lol. I really have to dig for the cross sectional area, you have to learn it to pass the test, then you never use it. And of course my cheat sheet isn't helping. Here is what I have on it. Diameter inches = 0.0640 = 4107 Circular Mils (d^2) 1 Mil = .001". So my guess would be [b]. Hope this helps. SEMPER FI Happy Holidays - Jeff
