Use a conduit bender to bend thinwall conduit as shown in
Figure 10-11. To make a smooth, even bend, take short bites. Be sure
to follow instructions provided by the manufacturer. A little experi-
menting with a bender will enable you to get the knack of using it.
Do not have more than four quarter bends in a run of conduit from
one box to another. Avoid short bends.
In areas where conduit runs along the side of a joist or stud, it
should be supported every 6 to 8 ft. with a pipe strap or clamp. In
areas where conduit runs horizontally across wall studs, notches
should be cut, which are then protected with steel plates. Holes can
also be drilled to provide a channel for the conduit, Figure 10-12.
Check the local building code.
The notching of studs can be eliminated, to a considerable extent,
by running the conduit across subfloors. When the conduit is in
place, furring strips are run up to the conduit. Finish flooring is laid
over the furring strips, Figure 10-13.
