What to Look for When Buying Wire Connectors

best-electrical-connectors

Whenever I am looking to buy any tool, I usually look at the brand first. However, when it comes to the best wire connector, the brand is not that important. As long as a connector meets all the criteria you need, it would do.

Here are the things to consider when purchasing wire connectors:

  • Compliance or Certification in Product Safety Standards

Because wire connectors deal with electricity, it’s essential to have safe and durable products. The only way to know this is to check if it complies with standards from various certifying bodies, like NEC and UL.

  • Types of Connectors

There are numerous connectors available on the market. That’s why you should know what you need first before making a choice. There are butt connectors, wire tap connectors, T-tap connectors, splice connectors, and heat shrink connectors.

You can look at your current system to determine your needs. Is it for automotive applications? Or for your home? Do you need to install it permanently? Does it have to be waterproof? If you’re unsure, it’s best to consult a licensed electrician to get the best advice.

  • Tools Needed

Some connectors require a crimper to install, while some use a heat gun. Some connectors require both tools to ensure a proper connection, while some don’t need tools at all. That’s why it’s essential that you first determine what you need before embarking on an installation project.

If you have complete tools as a DIY professional, you might not need to consider this. But if you are a beginner who lacks tools, you should check the required tools of a product. Some connectors even required specialized tools for proper installation.

  • Material Used as Connector Inside

This refers to the core material the connector uses to conduct electricity. Is it made from copper or premium brass? Is there a solder ring that provides a good connection once set? It is crucial you know this material to ensure an excellent electrical flow in your system.

  • Sizes Included in the Package

You should know this because not all packages provide the same number of connectors. Some items come with a limited number of connectors for thicker wires, limiting their usability for projects that require large AWG cables.

Furthermore, if you’re working on multiple projects at a time, it’s great to have more connectors so you don’t run out while you’re in the middle of an installation.

How Do You Connect Three Wires Together

best-automotive-wire-connectors

In the usual way of connecting two or more wires, you could use wire nuts. However, it is much easier to use a three-wire connector.

You can use a three-conductor splice connector, where you just need to strip the wire end and insert it into the connector. Alternatively, you can use a T-tap wire connector where you simply put the wire in and lock its cover.

Are Push-in Wire Connectors Better than Wire Nuts

Both the push-in wire connector and the wire nut provide an excellent connection. These connect the wire by ensuring a good connection between the two separate cables. However, these differ in application.

Wire nuts require proper wire stripping and splicing technique to ensure a good connection. On the other hand, push-in wire connectors are easier to install.

Push-in wire connector types require no tools at all. Some other wire crimp connectors need a heat gun, a crimper, or both. Nevertheless, the primary advantage of wire connectors over wire nuts is their ease of installation. But as long as appropriately installed, both would provide a safe and reliable connection.

Are All Wire Connectors Insulated

No, not all connectors are insulated. There is also a non-insulated wire connector and terminal type, mainly used for wiring lines not in danger of short circuits when touching.

These non-insulated connectors and terminals are also less expensive if you compare them to the insulated terminal. However, using an insulated wire connector is much safer than a non-insulated wire connector. It has tubing covering the barrel opening, which makes it safer even though it touches some other wires.

Do All Types of Wire Work With Every Connector

Most wire connectors can support any wire, but some wire connectors are not recommended for use with fine-stranded wires. Some crimp-type connectors can connect this type of wire, but it may loosen its hold over time, especially if the wire moves or vibrates.

Conclusion

Using insulated wire connectors is the easier and faster way of connecting a wire nowadays. There is an appropriate wire connector for connecting a solid wire, a stranded wire, or both.

If you want to find the best wire connectors for your application, you should look at your system. If you’re unsure, you can look at the criteria I have or ask a licensed electrician about your specific plan.
