Many people join electric wires with electrical tapes. Some twist the wires together and wrap them with electrical tape. Electrical tapes are not secure connectors. They are vulnerable to being damaged too. The best wire nuts are safer wire connectors.
It is common to need wire connectors when working on circuit connections for switches, outlet receptacles, light fixtures, and other devices. Wire nuts are small rounded caps that twist bare wire ends to create tight and secure connections.
There are actually two kinds of wire connectors: wire nut and push-fit-type wire connectors. Wire nuts are a better option because they are cheaper and reversible. Wire nuts are easier to unscrew when you need to replace remove a device.
Wire nuts come in cone shapes. They have ridges on the sides to allow your fingers to have a firm grip on them. A little square-cut spring can be found inside the cone to provide tension on the wires to securely hold them. The spring inside the wire nut tightens the wires make a secure connection.
Wire nuts come in different sizes for different wire sizes. They also come in different colors to indicate type, quantity, and size of wires they can accommodate. Colors vis-à-vis sizes vary per manufacturer.
Below we take a look at 4 best wire nuts on the market:
This AUSPA Lever-Nut Conductor Compact Wire Connectors comes in a pack of 30 pcs- 10 each of the sizes 22-412, 2222-413 and 222-415. This pack comes with levers that have 2, 3 and 4 wire sockets are independent of each other.
These wire joiners are easy to use. Strip the wires. Pull the levers back, slip the wires and close the levers – that simple. Using this connector you are sure that the ends of the wire will go all the way to the nut. When the lever is down you are sure that wire is firmly tugged in.
A user says this is an amazing product. He has tried them with twisted/solid core//braided wires and they were able to hold on very well. He says twisted cables will firmly be attached even if the ends are not soldered.
The trick to easily insert the wires is to make sure the wires are stripped to .37 inches long. It also helps a lot if the wires are straight. If you are small stranded wires, strip longer, fold the wire back, twist it and insert to the lever. This wire connector has a 440V rated voltage and a 32A rated current.

How to Use Wire Nuts
A set of wire nuts often come with instructions on how to use them. This is so because different manufacturers have specific techniques on how to easily use their wire nuts. Here is the standard and most common way to use wire nuts.
- Using a wire stripper, strip the ends of the wires of their insulations (about ½ inch). Be careful not to cut through the metals of the wires.
- Align the ends of the wires and securely hold them together.
- Insert the wires into the right size wire nut.
- Twist the wire nut clockwise as tight as you can until there is no bare wire protruding below the nut. If you are able to effortless twist the wires in the wire nut, chances are it probably has not properly gripped the wires. Make sure to push the wires far enough. Make sure too that the wire nut is not too big for the wires.
- Test the connection by tugging each wire. If wire pulls out, take off the wire nut and re-insert the wires.
After successfully inserting the wires on the wire nut, test the connection and check if the wires are passing any current through the connection.
Safety of Wire Nuts
Wire nuts are safe when they are of the right size and are properly installed. Many new electricians are however not comfortable in using wire nuts. Fact is, this connector is extremely safe and can withstand any abuse without the risk of breaking. Wire nuts have been used for many years and electricians have rarely had any safety-related issues with its use.
