The offset is the preset distance that is marked on the shoe of the bender. This preset mark allows for shrink back when bending. It allows you to make a perfect bend if a conduit run comes to a wall and has to go up the wall. It takes into account the outside diameter of the conduit and adds it to the shrink back of the bend to make the conduit fit exactly up against the 90 degree angle of the wall.

What is the multiplier for 45 degree offset in conduit bending?
Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.
What are the 4 types of electrical conduit bend?
The 'Stub-up', or 90º bend, Back to Back Bends, Three Bend Saddles, and offset bends.

When installing surface mounted cable the best method of ensuring that it is kept straight is by?
When installing surface mounted cable the best method of ensuring that it is kept straight is by using more fasteners that is required by the electrical code. Another way is to install it into a conduit chase. The conduit can be fastened to the building using a level to keep it straight. The cable can then be pulled into the conduit.
Is it legal to support a conduit from another conduit of the same size?
No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
