Questions 19 – 21 refer to the following procedure.
Electrical conduit fittings form the outer covering for most electrical wiring from one
point to the next. They shield the wires from the external environment so as to make the wire
last longer and also to keep humans and pets safe from electric shocks or other such
vulnerabilities. Electrical conduits are predominantly made of insulating and sturdy material
for optimum functionality. Here are the ways to do the simple ones:
1. Choose the right material for installing electrical conduit fittings. The most preferred
material is known as EMT (Electrical Metallic Tubing). EMT is very easy to install as
you can effortlessly bend it and assemble it as per your needs.
2. Chalk out a wiring plan: Find out the location of the electrical boxes on your wall to trace
the route of the conduit. Draw the path from the main power source to the electrical box.
3. Measure the amount of conduit that you would need: Make appropriate marks in pencil
wherever you think the bends should be, and measure the total length of the conduit that
would be needed to finish the entire electrical conduit fittings. Now cut the length that
you just measured with a tool called hacksaw.
4. Make the necessary bends: It is now time to make bends that you had marked on the pipe
in the previous step. Owing to the easy flexibility of EMT, this should not be very
difficult. Conduit benders come in handy for doing this bending.
5. Attach fitting to the wall: You can use screws and straps with either single or double
holes, available at electrical surplus shops, to attach electrical conduit fittings to the wall.
6. Tape the ends and put the wires in place: Use a widely available fish tape and run it
through the entire route of the conduit fittings you just installed.
