90 degree bend
Ans: A bend that changes the direction of the conduit by 90 degrees
Question: Back-to-back bend
Ans: Any bend formed by two 90 degree bends with a straight section of conduit
between the bends
Question: Concentric bends
Ans: 90 degree bends made in two or more parallel runs of conduit with the
radius of each bend increasing from the inside of the run toward the outside
Question: Developed length
Ans: The actual length of the conduit that will be bent.
Question: Gain
Ans: 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 degree bend
Question: Offset
Ans: An offset is two bends placed in a piece of conduit to change elevation to
go over or under obstructions or for proper entry into boxes, cabinets, etc.
