A duct bank refers to a group of electrical conduits that provide pathways and protection for electrical wiring. Duct banks are typically installed underground for large buildings that require substantial wiring.Conduit bending is one of the first skills learned by new apprentices in a commercial or industrial shop. They learn to use multipliers for 15°, 30° and 45° for offset bends. Most settle in on the 30° bend since the multiplier is 2. It makes the math very easy. However it makes for less than aesthetic appearance if the offset is less than 6".Multiplier (Cosecant) Method# Typically when bending conduit you decide the theta, and the hypotenuse (distance between bends) is the unknown value. In order to find these unknown values quickly by hand we’ll use the multiplier method. This is the most common method to conduit bending. It uses the cosecant (1/sin) from the theta (bend).
