For the remaining problems in this lesson, you will use the bender chart shown. Allow an
additional half-inch of length for the threads in any of the problems which require an additional
length of conduit to go into a junction box or conduit fitting. Keep in mind that in the field it might
be necessary to add significantly more than this amount.
