90° bend A bend that changes the direction of the conduit by 90° back-to-back bend Any bender formed by two 90° bends with a Straight section of conduit between the bends Concentric Bends 90° bends made in two or more parallel runs of conduit with the radius of each been increasing from the inside of the run toward the outside Developed Length The actual length of the conduit that will be bent Gain Because a conduit bends in a radius and not at right angles, the length of conduit needed for a bend will not equal the total determined length. Gain is the distance saved by the arc of a 90° bend Offset An offset is two Bends place in a piece of conduit to change elevation to go over or under obstructions or for proper entry into boxes cabinets and etc. Rise The length of the bends section of conduit measured from the bottom, centerline, or top of the straight selection to the end of the conduit being bent Segment bend A large bend formed by multiple short Bends or shots Stub up Another name for the rise in a section of conduit at 90°. Also, a term used for conduit penetrating a slab or the ground The first bend made with a hickey should be about 10° A 90° bend is also known as a Stub

Making a saddle bend around a 4 inch obstruction will cause the center of the saddle to shorten by 3/4 inches Which of the following blades should you select when using a hacksaw to cut EMT 10 teeth per inch When using a pipe cutter, tighten the cutter handle 1/4 turn for each full turn around the conduit Smooth the cut metal conduit edges using A reamer Conduit dies cut a taper of 3/4 of an inch/foot When cutting and joining PVC, Use PVC cement on the ends of both pieces to be joined The fuel bending of PVC requires a Heating unit You can use a hickey to bend RMC What is the key to accurate bending with a hand bender Constant foot pressure on the back piece as well as force on the handle In a right triangle, the side directly opposite to the 90° angle is called the Hypotenuse Prior to making a 90° bend, which two measurements must you know? Stub up distance and take up distance A back to back bend is Two 90° bends made back to back on a single piece of conduit To prevent the ends of the conduit from being uneven, what additional information much you use when making parallel offset bends. Center to center spacing and tangent of 1/2 the offset angle When making a saddle bend, the center of the saddle will cause the conduit to shrink ______ for every inch of the saddle depth. 3/ Which of the following is typically threaded using a ratchet threader RMC The sizes of conduit that can be been using a hand bender are 1/2 inch through 1 1/4 inch If a bender can be used to bend 3/4 of an inch or MC, then it can also be used to bend ________ EMT

1 inch The take up on 1 inch EMT is Eight Take up on half inch RMC is 6 inches On an offset using 30° bends and a depth of 6 inches, the conduit shrink is One and a half inches On an offset using 30° bends and a depth of 6 inches, the distance between bends is 1/ The multiplier for determining the distance between bends is _____ when bending offsets using 30° bends

The multiplier for determining the distance between bends is _____ when bending offsets using 45° bends
