There are a wide range of electrical terminals you can select when doing an electrical wiring project. This article tells the difference between ring and spade terminals.

Ring terminals are very effective connectors that create very secure connections. These devices come in various configurations and are either insulated or non-insulated. Insulation comes in the form of vinyl and nylon. When repairing electrical wiring or adding new connections, the installation of the ring terminals is essential to the whole process.

A ring terminal is used for connecting two or more wires to any single point of connection, for example, a circuit protection device. Ring terminals are available in butted seams which are serrated on the barrel in order to provide additional grip and straightforward insertion of electrical wires. Some manufacturers also stock ring terminals having a brazed seam, which is quite similar to a butted seam, but it provides additional strength to crimp in any position over the barrel.

Crimp systems are designed to compact the wire strands together to a set level so that no interstitial spaces (gaps) are left between the strands. This stops both moisture and oxygen entering the crimp and therefore prevents corrosion from occurring.

Many times the Electrical issues is intermittent, where sometimes the circuit works, and sometimes it does not, meaning that you have to be able to track down the problem while it is not functioning. Most often, these issues are the result of a poor connection. Once you have the problem located, you need to fix it.

There are three common hand tools that you will need for any electrical service work- cutters, crimpers, and strippers. You can buy one tool that does them all, but it won’t do any of them as well as separate tools will.

PVC is replacing traditional building materials such as wood, metal, concrete and clay in many applications. Versatility, cost effectiveness and an excellent record of use mean it is the most important polymer for the construction sector, which accounted for 60 per cent of European PVC production in 2006.

Solderless terminals are used to finish the connection to thousands of different electrical installations. They are very versatile and come in many styles to suit many applications. They are made of copper (economy versions use brass) and they are tin-plated to prevent corrosion.

Knowing the basic wire types is essential to almost any electrical project around the house. When you’re install new wiring, choosing the right wire or cable is half the battle. And when you’re examining existing wiring in your home, the wiring type can tell you a lot about the circuit the wiring belongs to. Any new electrical installation requires new wiring that conforms to local building codes.
