IE2- Basic Conduit Bending

The _____________ of a 90 degree bend is the longest length from the end of the straight section of pipe to the bend

• Gain

• Stub length

• Leg length

• Take-up

The first of the five steps used to determine bender take-up is:

• Measure the stub length

• Bend a 90 degree stub

• Subtract 10 inches from the stub length, the remainder will be your take-up

• Measure and mark ten inches on an appropriate stick of conduit

For larger jobs, it can be about ____________ percent more expensive to used connectors to change the direction of the conduit rather than bending.

• 20

• 30

• 40

• 50

The ______________ is the distance measured from the top or bottom of an offset parallel to the opposite (top or bottom) side of the remaining parallel.

• Angle of offset

• Bend centers

• Actual depth of offset

• Overall offset

The ________________ depends on the size and type of conduit used and determines the radius of the bend

• Bender shoe

• Hook

• Sight Gauge

• Foot lever

A _______________ has a much smaller “shoe” and must be repositioned several times along the conduit in order to properly bend conduit.

• Hand bender

• Hickey

• Mechanical bender

• Power bender

The ______________ operates by looking straight down at the indicator and comparing it to the five calibrated bending degree marks on the shoe.

• Hook

• Sight gauge

• Positioning indicator

• Finish indicator

The first thing an electrician should do when beginning work with a bender is to determine the ____________ of the bender being used.

• Gain

• Stub length

• Leg length

• Take-up

Step 1 of the four step procedure used to determine and locate the bend centers of an offset bend is: __________________

• Multiply the offset depth by the proper shrinkage per inch of offset depth value

• Determine the angles of offset that will be used

• Determine the offset depth needed

• Multiply the offset depth by the proper constant multiplier.

he formula ______________ can be used to determine the length of conduit required to bend a 90 with proper leg and stub length, where: LC = The length of conduit required to make the bend LL= Desired leg length of 90 degree bend, LS = Desired stub length.

• G= LL + LS + LC

• G= LL + LS - LC

• LC= LL + LS + G

• LC= LL + LS - G
