How to Use Wago Connectors?

What are Wago wire connectors?

Wago offers a great variety of wire connectors for your increased convenience and ease of use in electrical wiring, including but not limited to:

• 221 Series Lever-Nuts
• 2773 Series WALLNUTS
• 243 Series MICRO PUSHWIRE
• 224 Series Inline Connectors
• 873 Series LUMI-NUTS

These models make your life with electrical wiring so much easier, such as Wago's 2773 series Wallnuts, where you don't have to twist or crimp wires to make connection, just simply push wire into the connector and you're good to go.

What is a wire nut?

A wire nut is a little plastic cap, also known as a twist-on connector, that covers wire connections and keeps them intact. To use a wire nut connector, you need to strip the two ends of wire that you want to connect and insert them into the plastic cap and manually twist the cap until the wires bind together. While these plastic caps are strong, be careful, because twisting them too loosely will not provide a secure connection. On the other hand, twisting them too tightly can cause wires to pop out of the connection or even damage the connector or wires themselves.

What are splicing connectors?

Wago wire connectors make splicing stranded, fine stranded, and wire connections so much easier than similar products on the market like wire nuts and electrical tape. Splicing connectors take two wires and cut through them and their insulation jackets, crimping them together to form a connection without soldering.

What are the wire conductor types?

A stranded conductor is made up of several smaller wires that are bundled together, making them a lot more flexible and malleable than solid wire. Stranded wire creates less heat, allowing for a safer current flow, effective termination of patch cable connections/crimp, and doesn't sever or split, making it great for twisting to fit complex shapes or into small spaces.

Stranded wire is commonly used for indoor applications such as speaker wires and other electronic appliances.

A fine stranded conductor is even more finely stranded than your regular stranded conductor. Finely stranded conductors make use of a higher number of bundled together wires that are significantly thinner than stranded wire.

Finely stranded wire is often used in portable power cords and in welding cables.

A solid conductor is made up of one singular, solid strand of metal wire. Solid conductors are a lot more rigid and less flexible than the other conductor types, making it more prone to damage or completely breaking if frequently bent or flexed. However, solid wire offers perfect connection and termination due to only using one wire. Solid wire is also anti-corrosive, ideal for long distance applications, and is typically less expensive than stranded wire.

Solid wire is used more commonly in various outdoor applications, vehicle controls, and is also used in building structures to transport strong currents throughout the building.

How to use Wago wire connectors?

The Wago 221 Series Lever-Nuts are splicing connectors that can connect solid, stranded, and flexible copper wires. Wago 221 Series Lever-Nuts cover wire gauge sizes in two ranges from 24-12 AWG and 20-10 AWG. Using a Wago 221 connector is incredibly easy. Wago's Lever-Nut technology simplifies wire connection with their 4-step process:

• 1. Strip wires to desired length
• 2. Lift the lever up of the connector
• 3. Insert the wire into the connector
• 4. Drop the lever back down to lock the connection

A great advantage of the Wago 221 series is that they are packaged in a clear, transparent housing that makes properly positioning wires easier.

The 222 Series Lever-Nuts can accept wire gauge sizes from 28 to 12 AWG from each conductor type. Be sure to check the bottom of your Wago wire connector to verify. Once this is done, just pop the lever open, push your wire in, and clamp the lever closed again. It’s that simple.

The Wago Pushwire 773 Series Wall-Nut series push wire connectors clamp stranded or solid conductors. The Pushwire 773 series Wall-Nuts accepts wire gauge sizes of 18 to 12 AWG for both solid and stranded conductors. Be sure to check the built-in strip-length gauge to verify. Once the conductor is stripped, just simply and firmly insert it into the connector.

Are Wago connectors safe to use? Do Wago connectors need to be in a box?

Yes. Wago connectors are UL listed, which means they are up to code and approved for use in electrical work. To continue their safe use, you must contain any spliced wire connections inside a distribution or junction box.

Are Wago connectors reliable?

Wago's wire connectors are extremely reliable, providing secure wire connections over and over again as they are also reusable.

Shop HomElectrical to find a great selection of Wago's splicing connectors, including connectors in the Wago 773 series like this push wire connector with four connection points. You can also find connectors from the Wago 221 series like this compact splicing wire connector with three connection points.
