What is the total amount of bends on a 3 point saddle?

The most common type of 3-point saddle bends consists of a 45-degree bend in the center and a 22.5-degree bend on either side. To determine where to place the center bend along the conduit, add the shrink amount and distance measurement together.

What is the star for on a conduit bender?

Star: Indicates back of 90° bend, for back to back bends. D. Marks: The degree marks indicating the angle of the pipe bent.

How do you calculate bends in conduit?

Measure from the end of the conduit and make a mark at 7 inches to indicate the start of the bend. Slip the end of the conduit into the bender so the 7-inch mark is aligned with the arrow. This 7 inches, plus the “Stubs 5 to arrow” will give you the total horizontal run of 12 inches, including the bend.

What is the minimum bending radius for 3 rigid conduit?

Flexible conduits such as flexible metal conduits and nonmetallic conduits have similar rules for minimum bend radii. Bends must be made so that the minimum radius rules are followed, i.e., four inches for 1/2-inch conduit, 4 1/2-inches for 3/4-inch conduit, etc.

How do you make a 3 Point saddle with conduit?

1 When making a 3-point saddle, you should always create the center bend first. 2 Squat into the bend and bend your knees as you push on the conduit. 3 For a 30-60-30 saddle, push the conduit until it lines up with the 60-degree line on the bender head.

What saddle bends can be made in EMT conduit?

He has extensive experience in most areas of the electrical trade. This section of the conduit bending guide will address bending both 3 point and 4 point saddles in EMT conduit (they can also be bent in either IMT or rigid conduit as well using the same procedures). These are the two common saddle bends made in electrical conduit by electricians.

What is a 3 Point saddle Bend?

The most common type of 3-point saddle bends consists of a 45-degree bend in the center and a 22.5-degree bend on either side. To determine where to place the center bend along the conduit, add the shrink amount and distance measurement together.

How do you use a conduit Bender?

Once you’ve marked out a line for each bend on your conduit, use a conduit bender to bend a 45-degree angle in the center, followed by 22.5-degree angles on either side.
