Where is the strip gauge?
A "strip gauge" is often provided near the terminal of devices (switches, outlets, etc.) and should be checked before striping insulation. Additionally, the packaging of wirenuts and other connectors usually indicate how much insulation should be removed from a wire or cable.
Can you nick a wire in insulation?
It is very important not to nick the wire in the insulation striping process. The size of the wire is critical, and a nick can create a hot spot whenever the circuit is loaded. This resulting spot expands and contracts with each heating and cooling cycle, and over time, effectively loosens the connection.
What is the best way to splice two wires together?
Wire stripper. Wire cutter. Electrical wire connector. Electrical wire connectors are a common and easy way to splice two current-carrying electrical wires together. Unlike many electrical wiring projects, installing an electrical wire connector is easy enough for a non-professional to do and requires very few tools.
Why does my wire connector pop off?
If the wrong size wire connector has been applied, it may pop off when the wire expands or simply fall off when the wire contracts. Either way, the conductors of the wires will be left exposed, which can potentially cause all kinds of problems.
How to choose the right size wire connector?
To choose the right size wire connector, look on the side of the connector box and make sure that the connector being used is rated for the size of the wire it is being connected to and also for the number of conductors that are in the wire.
Why is it important to choose the right size wire?
Almost as important as turning off the power, choosing the right size wire to connect for the job can prevent mechanical and electrical failure and prevent electrical fires. The reason for this is that when a switch or device is turned on, it causes an electrical current to flow through to wires and into the wire connector. Once the current reaches the connector, it encounters a mild resistance in its flow. The resistance causes the wires themselves to heat up slightly which, in turn, causes them to expand.
Why do wires expand when a switch is turned off?
The resistance causes the wires themselves to heat up slightly which , in turn, causes them to expand. Once the switch is turned off again and the current has been stopped, the wires will cool and contract once again to their normal size.
1. Twist and Tape
For any project where you need a temporary fix, or a project that will be largely stationary, a simple twist of wires wrapped in electrical tape can do the trick. While this is in no way as viable as other methods on this list, it can certainly do in a pinch!
2. Soldering
The natural progression from twist and tape, soldering provides you with a secure, electrically sound, and budget-friendly method of joining two wires. The tradeoff for this is twofold – the cost of admittance with the purchase of a quality soldering iron, and the learning curve associated with proper soldering practices.
3. Heat Shrink Butt Connector
Combining the reliability of a solder joint with the ease of use of twist and tape, the heat shrink butt connector is an easy and clean way of splicing wires together. While a soldering iron is not required, you do still need a heat source of some sort. According to the manufacturers of these connectors, a heat gun is the way to go.
4. Crimp Butt Connector
For something with the strength of solder but none of the heat, a crimped connection is the way to go. Requiring only a crimping tool and the proper connectors, crimping provides a super solid splice with minimal cost of entry.
5. Terminal Blocks
One of the quickest and bulkiest methods of splicing wires, the terminal block provides a flexible connection without requiring any specialized tools. If you have a screwdriver, you can utilize a terminal block.
Splices – Making the Most of the Wire You Have
