There are various types of electrical conduits that are made from different materials like plastic, metal or fiber. Metal conduits are proven to be more durable and efficient in protecting electrical wiring or cables. Electrical wiring won't always be installed in a straight line so you need to bend the conduit to follow the wire's direction.
- Get the tools and equipment you need. Purchase an electrical conduit at your local hardware. Next you will need a tape measure that you will use to measure the area the conduit will occupy and the conduit itself. When you purchase the electrical conduit, take note of its size because that will determine the type or size of bender you will use. A pencil will be handy to mark measurements on the conduit's surface area. Purchase a level to check if the surface or ground you will be working on is level. This is important to ensure you are going to make a proper angle on the bend.
- Take measurements. Using the tape measure, measure along the wall or area the conduit will occupy and make sure you mark where the bends will take place. You will use these measurements to determine the length of electrical conduit you will need from the beginning point to the end. Be sure you consider the bend's measurements on the surface because this will affect the conduit's total length. Making a 90 degree bend on a conduit will use 6 to 8 inches of take up or bend so you need to mark out the measurements on the wall and the conduit to be certain you cut the right length.
- Know the parts of the bender. The conduit bender has several parts you need to know. The long pole is the handle where you will be holding onto. The footrest is where you will place your foot to help with the bending. You will notice at the other end of the conduit bender there is a lip or hook like feature across the footrest; this is where you put the conduit on to. There will be markings on the bender like an arrow near the lip and a star at the middle of the bender. There will also be degree markings on the side of the bender so you can see if you've made a 90 degree bend.
- Use the conduit bender. Place the conduit onto the lip or hook part of the bender and make sure the arrow lines up with first marking of the take up marks. If you've made the proper take up or bend measurements the star should line up at the middle of the bend and the footrest will line up with the second take up mark. Use the level to find a nice level spot on the floor or ground; this will be the bending area. Hold on to the handle and place your foot on the footrest and pull the handle towards you, then put weight on your foot to help bend the conduit. Make sure you put consistent pressure so the bender won't slip and cause the conduit to move from the markings. You can place your other foot on part of the conduit to keep it from moving. When you've made a good 90 degree bend you can now remove the bender.
The electrical conduit may prove to be hard to bend, but using a conduit bender and a little elbow grease will help you make a 30, 60 or 90 degree bend.
