Hey there! As a supplier of PVC insulated double sheathed cable, I often get asked about how to install this type of cable in conduit. It's a crucial process, and getting it right ensures the safety and efficiency of your electrical system. So, let's dive into the step - by - step guide on how to do it.

1. Planning and Preparation

Before you start the installation, you need to do some planning. First, figure out the length of the cable you'll need. Measure the distance from the power source to the destination. It's always a good idea to add a little extra length to account for any unforeseen twists and turns.

Next, choose the right conduit. The size of the conduit depends on the number and size of the cables you're going to run through it. You want to make sure there's enough space for the cables to fit without being too cramped. For PVC insulated double sheathed cable, a rigid metal or PVC conduit is usually a good choice.

Also, check the local electrical codes. Different areas have different regulations regarding cable installation. You don't want to end up with a non - compliant installation, so make sure you're following all the rules.

2. Gathering Tools and Materials

You'll need a few tools for this job. A cable cutter is essential for cutting the cable to the right length. A fish tape can be really helpful for pulling the cable through the conduit. You'll also need a drill if you're going to mount the conduit. And don't forget some electrical tape to secure the connections.

As for materials, obviously, you'll need the PVC insulated double sheathed cable. Make sure you have enough of it. You'll also need the conduit, conduit fittings like elbows and couplings, and mounting brackets to hold the conduit in place.

3. Installing the Conduit

First, mark the route for the conduit on the wall or ceiling. Use a level to make sure it's straight. Then, drill holes for the mounting brackets and attach them to the surface.

Once the brackets are in place, start assembling the conduit. Connect the sections using the fittings. Make sure the connections are tight to prevent any moisture or debris from getting inside.

If you need to make bends in the conduit, you can use a conduit bender. Just follow the instructions on the bender to get the right angle.

4. Pulling the Cable through the Conduit

This is where the fish tape comes in handy. Start by feeding the fish tape through the conduit from one end. Once it comes out the other end, attach the cable to the end of the fish tape.

Slowly pull the fish tape back through the conduit, and the cable will follow. Make sure to pull gently to avoid damaging the cable. If you're running multiple cables, it's a good idea to tie them together loosely so they pull through more easily.

5. Making Connections

Once the cable is in place, it's time to make the connections. Strip the insulation off the ends of the cable using a wire stripper. Make sure you don't cut into the conductors.

Connect the cable to the power source and the destination using appropriate connectors. You can use wire nuts or terminal blocks, depending on the type of connection. Wrap the connections with electrical tape to insulate them.

6. Testing the Installation

After you've made all the connections, it's important to test the installation. Use a multimeter to check for continuity and proper voltage. Make sure there are no shorts or other electrical problems.

If everything checks out, you're good to go. Your PVC insulated double - sheathed cable is now installed in the conduit.
