How to Make a Safe Wire Connection

A good day for an electrician is not ending up like smoldering and shaking like one of those cartoon characters who touched a live wire. To make sure this never happens to you, take note of some precautions and electrical safety tips for when you are installing a wire connector.

Tip #1: Shut Off the Power

The first thing that you want to do before you begin making a wire connection is to make sure that you have turned off the circuit breaker. Even if the circuit breaker has been turned off, you will want to make sure that there’s no electricity running through the wire. Using a non-contact voltage tester, you will be able to confirm that the electricity has stopped. It is also highly recommended that you wear rubber gloves during this process to reduce the possibility of an electrical hazard.

Tip #2: Strip the Insulation

Second, you want to remove any insulation that may be on the wires. It’s common to use a wire stripper for this. If you’re looking for a new wire stripper, or buying one for the firsttime, consider getting one that can work both as a wire cutter and stripper.

If you’re unsure of how much insulation you need to strip in order to create a strong and proper electrical connection, you can look on the packaging or the back of the connector itself.                                                        



                                                                                                                                               Push in wire connectors       Wire nuts                                             

Tip #3: Choose Your Connector

The type of wire connector that you decide to use can change the way you splice the wire. These include wire nuts, lever connectors, push-in connectors, and more. We recommend using a Wago brand connector, which comes in multiple types. All of them are easy to use no matter which you choose.

Tip #4: Create a Strong Connection

Regardless of what type of connector you decide to use, be sure that you’re creating a strong electrical connection. A loose electrical connection is like a speed bump on the road. It will end up slowing down the electrical current while creating friction and heat. Too loose of a connection can also cause electricity to leap through the air from one conductor to another; this is known as arcing.

Both of these are fire hazards, so you need to make sure there is a strong connection in order to avoid it. A Wago lever and push in connector feature an opening that lets you check the electric continuity or voltage without removing the wires and this will help when creating a long lasting connection.
