The combination hydraulic benders, which can handle up to four-inch conduit (the maximum sizes of EMT and IMC conduit), are the most popular. With some models, users can make a full 90-degree bend in one shot or can use segment bending to make a larger sweep.
What's the maximum bends in conduit run?
National Electrical Code or NEC limits the total number of bends in one continuous run to 360 degrees or four 90 degree bends . It specifically states, “There shall not be more than the equivalent of four quarter bends (360 degrees total) between pull points, for example, conduit bodies and boxes.”
What is the largest EMT conduit that can be bent with a hand bender?
Electrical Metallic Tubing (EMT): conduit made to protect conductors and cables, also known as thinwall. Manufactured in 10′ lengths, in sizes ranging from 1/2” to 4”. EMT sizes 1/2”, 3/4”, 1”, and 1 1/4” can be bent using a hand bender.
Can you bend 2 inch EMT?
