Can You Use Electrical Tape Instead Of Wire Nuts?

Source

Both electrical tapes and wire nuts help connect electrical wires. On the one hand, electrical tape is vulnerable and prone to easy damage. On the other hand, wire nuts provide pressure for the electrical wire and ensure a good connection. Having known this, you’re asking. Can I use electrical tapes instead of wire nuts?

Electrical tapes are one of the alternatives to wire nuts because they protect the wire from exposure that can cause damage. However, they’re not a permanent wiring project solution because if the wire transmits too much heat, it will cause the tape to melt.

Can You Use Electrical Tape Instead Of Wire Nuts?

You can use electrical insulation tape instead of wire nuts. An electrical tape is a thin material with adhesive on one side that makes it stick to electrical wires. Although they’re inexpensive and easy to use, they’re unreliable. People prefer to use electrical tapes with other electrical wiring tools.

The reason is that although they’re quick and cost-effective, the electrical straps are not durable, mostly when they absorb so much heat. For this reason, it is unsafe to use electrical tapes on wires with high voltage.

What Can I Use If I Don’t Have Wire Nuts?

Wire nuts make it easy for you to join electrical wires together. But, due to their expenses, you likely want to opt for other alternatives if you don’t have wire nuts. Here are a few wire connection tools you can choose from:

1. Scotch-lock Connectors

This type of electrical wire connector provides double protection for wires. They can trip wires off if the voltage is too high. Asides from that, they are water resistant.

How To Use:

Scotch lock connectors usually have two openings with metal in the middle. Pick the wires you want to connect. Insert them into the opening, then use a plier to press the metal to help seal the connector.

2. Electrical Tapes

An electrical tape is a tool that helps conduct electricity between wires by preventing the accidental electric current from flowing from one wire to the other. However, you can only use them for a temporary fix.

How To Use:

Simple unwind the electrical tape and cut out the piece you want to use. Place the wires together, then wrap them with the adhesive side of the strap.

Can You Put Electrical Tape Directly On Wire?

You can put electrical tape directly on the wire. It is one of the simplest ways to keep your wires safe and unexposed. Asides from safety, it protects you from electrocution or fire hazards.  Electrical tapes have adhesive o that makes it stick to the wires and protects them from causing damage.

However, this adhesive dries out over time due to the heat that emanates from the electrical wires.

Can Electrical Tape Catch Fire?

When you ask, “can electrical tape catch fire?” Fire here is relative because fires don’t just begin to burn on the tape. When your electricity voltage is higher than what the electrical tape can withstand, it will cause it to melt. When it melts, it becomes a threat to the wires in its protection.

It also causes damage that can lead to a fire outbreak. Although electrical tapes have a thermal conductivity that makes them withstand heat, they’re inflammable. However, they are not useless because they can resist heat to a certain level of 176 degrees.

One of the ways you can prevent your electrical tapes from melting is that you shouldn’t use them to cover damaged wires.

When Should You Not Use Electrical Tape?

If your electrical wire is damaged, it is not safe to cover it with electrical tape. The reason is that damaged coils are prone to a quick expansion of heat that can lead to fire explosions.

Other reasons you should not use electrical tapes are;

  • Never use electrical straps to seal up the loose ends of wires. When you use them to cover loose wire ends and connect them to the power supply, it can cause sparks which leads to electrocution.
  • Electrical tapes do not stand the test of time. The longest they can remain functional for wire protection is 5 years. This is one of the reasons it is the wrong choice for your permanent wiring projects.
  • If your electrical wire cuts into two with the metallic parts which the current flows through exposed, it is not advisable to wrap them with electrical tape. The reason is that the exposed metal transmits more heat, and when the heat is excess, it will cause the strap to melt and cause danger.
  • Never use electrical tapes to cover insulations like water pipes. The reason is that it causes the strap to become hotter, thus posing a risk of fire.

Can You Use Electrical Tape To Splice Wires?

Splicing wires is a technique you use to join two separate wires. Although you can use electrical tape to splice wires, it is not advisable. The reason is that joining two wires is likely to cause electric shocks. Nonetheless, there are ways you can splice your wires to make them durable. 

To fix this, you’ll need; two wires, pliers, electrical tape, and wire nuts.

  • Place the side of the wires together.
  • Use a plier to peel off the rubber patch on both edges.
  • Cover the cut part with the wire nuts. This wire nut will protect the wires and also curb the effect of the current it transmits.
  • Finally, wrap the electrical tape to hold the wire nuts and wires together.

Does Electrical Tape Prevent Sparks?

When you cover electrical wires with electrical tape, it functions as an insulator that helps conduct the electric current that transmits from the wire. Controlling the electric flow prevents sparks. The electrical tape also protects the electric wire from exposure which can cause electrocution.

However, it comes in a variety of colors that depict its usage.

  1. Grey electrical tape – for neutral wires with high voltage.
  2. Blue – for phase B wires with low voltage.
  3. Orange electrical tape – for wires with high voltage in phase B.
  4. Green with yellow stripe – suitable for underground wire connections. 
  5. Black – suitable for phase A wires with low voltage.

How Hot Can Electrical Tape Get?

Although electrical tapes can resist heat to a certain degree, it takes a lot of heat to affect the insulation strap. This explains why they will begin to melt when the electric current is very high. When the electrical tape melts, the adhesive that helps it stick will wear out, making the tape twist.

Wrapping Up – Can I Use Electrical Tapes Instead Of Wire Nuts

Although you can use electrical tapes to cover bare wires instead of wire nuts, it isn’t a permanent solution to your wiring needs. The reason is that when wires are connected, they become hot, and the heat can quickly melt the electrical tape.
