Electrical tape is designed to be used for a variety of demanding and challenging uses which can be anything from protecting water pipes to repairing minor electrical wiring damage. However there are times when this special tape should and shouldn’t be used and here are some tips on where best use your electrical tape to help make your job easier.

Don’t Use Electrical Tape as a Replacement for Wire Nuts

It is important when using electrical tape on electrical wiring such as light switches, outlets, and junction boxes that the tape is used as a temporary measure and not a permanent measure. The reason for this is that with close contact to bare wiring the tape may heat up causing it to degrade over time. This can be problematic especially if it is in contact with something associated with you or your family members. To make sure your family is protected at all times it is best to substitute electrical tape with wire nuts for permanent installations.

Use Only on Minor Cord or Wire Damage

Electrical tape can be used to repair minor wire or cord damage, although it shouldn’t be used if there are frays, cracks or exposed bare electrical wiring. If you have cords that have a nicked or cracked outer sheath but the inner insulation is intact then you may use electrical tape for a safer repair. If the electrical wiring is exposed it may cause the electrical tape to heat up causing a fire hazard. It is also advisable not to cover the electrical tape with flammable materials such as cloths or rugs to also reduce a fire hazard.electrical tape

Stretch the Tape as You Wrap

When applying electrical tape it is important to wrap it around the object properly to ensure that it works accordingly to how you need it to. To apply correctly it is designed to be stretched slightly allowing for it to adhere better to the object you are wrapping. Applying it loosely may cause complications with insulation protection leading to wire exposure.

Spray With Dielectric Spray

Spray the electrical tape with a clear coat enamel or another selected dielectric spray. This spray can help to protect the tape better and is able to provide increased insulation properties. When applying this spray it is important to turn off the power supply to the cabling until the spray is cured or dried.
