How do you use PVC tapes?

  When the electrical tape is properly applied, it can be a valuable asset for lots of different jobs like insulating motor lead connections. Having tips on how to accurately use a product can also save you some major frustrations.

   We will then dive into 5 tips on how to successfully use electrical tape to ensure a safe and trouble-free installation. Let's get started.

Tip #1: Select the appropriate grade

   In cold conditions, you will need to select cold weather tape for better adhesion. Standard electrical tape can be used for all other applications like indoor settings. You should always pay attention to the min and max temperature ratings of the electrical tape to ensure you are using the correct one.

Tip #2: Half-lap the tape

   Proper application of electrical tape is to half-lap, as shown in the picture, which results in a double layer of tape. The rule of thumb is to do a minimum of two half-lapped layers or one and a half times the thickness of the insulation of the wire that you are wrapping, whichever is greater. The tape should be thicker than the insulation, for added protection.

Tip #3: Stretch the tape as you wrap

   Electrical tape works the best when it adapts to the object to which it is being applied. When you go to apply your electrical tape to a cord or piece of wire, you should stretch the tape as you wrap. When the tape is stretched as its being applied, it will provide more insulation protection than when it is applied loosely. To create effective insulation, you should wrap the tape between 75% of its width to right before the breaking point. Doing this will ensure the tape will be able to withstand the elements. The last wrap should be applied with no tension to prevent flagging.

Tip #4: Don't use electrical tape as a replacement for wire nuts

When you wire junction boxes or outlets, you should not use electrical tape as a permanent connection insulator. There is an electrical current that travels through bare wire copper and it produces heat. This can cause the electrical tape to degrade over time. Some electrical tapes may be able to stand the heat, but most electrical tapes are not designed for this type of application.

In the event that you are using electrical insulation tape for a temporary pigtail splice, the electrical tape should be wrapped beyond the end of the wires, then folded backward. This leaves a protective layer that resists cut-through.

Tip #5: Use self-bonding tape for superior moisture resistance

Self-bonding rubber tape or sometimes known as self-fusing tape can be used to insulate and moisture-seal low voltage (typically rated to 600 volts) electrical applications. Rubber tape bonds to itself when it is wrapped, there is no "sticky" side like normal tape. You should stretch the tape to 3/4 of the tape's original width to secure a moisture-tight seal. Self-bonding tape is made from rubber resin which provides durability, tear, and abrasion resistance.
