Lab 2.3

Lab 2.3 (Measuring, Marking, Cutting,

Conduit Bending-45 degrees)

Intent:

In this activity, students will be able to identify the route of electrical conduit, bend conduit, cut conduit, ream conduit, bend (45s) and connect conduit to a metal box. Students will be able to apply knowledge of measuring, cutting, and manipulating hand tools.


Outcomes:

Students will be able to:

  • Apply previous knowledge of construction hand tools

  • Measure and layout conduit for bending 45 degree angles

  • Identify proper conduit bending, cutting, reaming, and connecting techniques.

Tools & Material:

  • Proper PPE

  • Tape measure

  • Pipe bender

  • Torpedo Level

  • Hack saw

  • Band saw

  • Pipe reamer

  • Slotted screwdriver

  • Linesman pliers

  • 1/2" Conduit (10')

I Do...

Instructor will:

  • Emphasize safety and check for proper PPE throughout the process

  • Explain why conduit needs to be bent at a curve rather than perfect right angle.

  • Discuss the need to bend sweeping curves with a pipe bender so that wire can easily be fished through long sections of pipe.

  • Demonstrate how to safely and accurately measure, layout, cut, ream and bend EMT (45s).

    • Cut a 10' piece of EMT into the following sizes

      • 3' (Cut using a bandsaw)

      • 3'-2 1/4"" (Cut using a bandsaw)

      • 3'-3 3/8" (Cut using a hacksaw)

    • Demonstrate how to ream the cut pieces of EMT and explain why its important

    • Bend each piece of emt at a 45 degree angle

Students will:

  • Actively listen

  • Take notes

  • Asks for clarification as needed

We Do...

Instructor will:

  • Emphasis safety concerns for this activity

  • Check for proper PPE

  • Facilitate student progress and give advice/instruction as needed


Students will:

  • Demonstrate proper safety techniques while wearing required PPE.

  • Obtain a 10' piece of 1/2" conduit

  • Measure, mark and cut conduit into three sections measuring...

    • 4' 0"

    • 3' 8"

    • 2' 3"

  • Ream each piece of conduit

  • Bend each piece of conduit at a 45 degree angle


You Do...

Instructor will:

  • Emphasize safety and check for proper PPE throughout the process

  • Check for proper PPE

  • Evaluate the students finished product for accuracy and sign Skills Evaluation Sheet.


Students will:

  • Demonstrate proper safety techniques while wearing required PPE.

  • Measure, mark, cut and ream a piece of EMT that measures 4' 5".

    • The cut emt must meet a tolerance of 1/16"

  • Bend the EMT at a 45 degree angle

  • Obtain a signature from the instructor for completing Lab 2.1
