Step by Step Installation Instructions

Determine length of cable run. Typically EMT comes in 5’ or 10’ lengths.

Run cable(s) through first piece of conduit

Using the straps and fasteners secure conduit to surface. Next you will need to run your cable through a coupler in order to connect your next piece of conduit. Note: attaching coupler to the emt prior to running the cable will save you the extra step.

When encountering obstructions or corners you may need to make a bend or attach a 90 degree coupler. You may also need to make cuts. Note: when pulling cable through a 90 degree bend or junction box, pull excess cable as it is difficult to pull through and might compromise your cable. Wire Lubricant is available to assist in pulling cable through conduit, be careful not to snag or tear the protective shielding when pulling cable through metal conduit.

When either separating or conjoining cable runs, you will need to use a junction box. They are sold in various shapes and sizes. When connecting to either a junction box or wall mount you will need to use a threaded connection coupler.
