The document outlines the procedures for bending electrical conduits, including various types of bends such as 90 degree, offset, and three saddle point bends. It details the equipment and methods required for properly bending different types of conduits, including steps for creating both a 90 degree bend and a PVC offset bend. This guidance is crucial for electricians and plumbers to ensure installations meet job requirements and function effectively.

2. Performance objectives
• Given the necessary equipment, tools
and materials, bend the electrical pipe
in line with the job requirements.

3. Bending conduits
Conduit bending is truly one of the
fundamental tasks of the electrical construction
industry. Whether EMT, galvanized rigid steel
conduit, or intermediate conduit, you will need to
bend it. Bends will be required as part of your
installation.

4. 90 degree bend
A 90 degree stub up bend is made by
bending a piece of piping into a 90
degree or 'L' shape. It is the bend
most commonly used by electricians
and plumbers. This bend is frequently
used to run conduit into electrical
boxes, run pipes up and down walls
and to run pipe into walls through
floors and ceilings.

5. Offset bend
Offset bend is a style of
bend that is built
independently of the 90° stub
and the Back to Back
bend and is an important
bend to know when running
conduit. It is common to shift
the conduit a certain
distance while continuing
to run parallel in the same
direction as the pre-shift
portion of the conduit.

6. Three saddle point bend
Three bend saddles are often used to cross or saddle a small
obstruction that would prevent the electrician from installing
conduit in a straight line. One of the obstructions that the
electrician most often has to saddle is another run of electrical
conduit or pipe that has been installed by a different trade.

8. PROCEDURES IN BENDING ELECTRICAL NON-METALLIC CONDUIT
MAKE A 90’ BEND
1. Draw a right angle on the floor using your try
square and chalk. This will serve as your guide
when forming your conduit into 90’ angle. ( A tile
on the floor can serve as a guide.)
2. If you are in a room with a tiled floor, you can use
it as your guide for 90’ angle.
3. Draw an arc near the corner with a radius of 100
mm; this will aid you in forming your elbow
correctly.

4. If the conduit is soften, turn off the heat gun and
bend the PVC to the desired shape using your arc
and 90’ angle guide drawn on the floor.
5. If the desired shape is formed, damp the conduit
with wet rug to harden it immediately. (You can use
your foot to hold one end of the conduit while
wiping.)

10. PROCEDURES IN BENDING ELECTRICAL NON-METALLIC CONDUIT
MAKE A PVC OFFSET BEND
1. Measure the elevation of the obstruction. In this case, let’s use
this wooden box.
Note: Remember, offset bent is used if the conduit crosses an
obstruction. In this case, the elevation is about 70mm.
2. Draw the depth of elevation on the floor as shown in the figure
using your try square and chalk. This will guide you how high your
offset bend would be.
3. Put mark of about 10mm and put another mark of about 200 mm
from your first marker.

MAKE A PVC OFFSET BEND
4. Plug – in the heat gun and apply heat to the conduit. Apply heat
between your markers. Apply heat evenly by turning over the conduit
while swaying your heat gun back and forth to avoid kinks during
bending.
5. If the conduit is soften, bend the PVC to the desired shape using
your guide drawn on the floor or in actual location. Pull the left portion
of the conduit while pushing the other end.
6. If the desired shape is formed, damp the conduit with wet rug to
harden it immediately. (You can use your foot to hold one end of the
conduit while wiping.)
