Take the length of the pipe, and multiple the number of conductors permitted in the size EMT.

Seems straight foward to me, 700' without looking in the book.

10 x 70' = 700'
If you looked at the book you would get:

279?70'=19,530'

Edit: Now we have a conduit size.

16?70'=1,120'

How about this? ... In a circuit where you install the maximum allowable number of #12 THHN wires,hooking them end to end, in a 70' piece of 3/4" EMT, and hook them to a continuous load on the maximum sized allowable breaker,... the load being installed on the end of the maximum length of LFMC that may be used without a ECG, in an ambient temperature of 556.67? Rankine, multiplied by the minimum required cubic inches of the two boxes?

There is a box on each end of the EMT and it is 10 ft from the breaker to the first box.


What is the electrician's name?

Is this an inductive load?

What is the total length of 10 AWG, Type THHN conductors that can be installed in a 70 foot length of EMT?
That's easy: 70 feet. You guys make everything complicated. :roll:

Let me know if you want the quantity of 70' conductors. :cool:

My mistake, I misprinted the question. Lets try again

What is the total length of 10 AWG, Type THHN conductors that can be installed in a 70 foot length of 1 inch EMT?
I still say 70 feet. Anything more would hang out of the ends of the tube. ;)
