For practically 200 years, copper has been the product of an option for electric connectors. Copper has actually been offered in electrical wiring because the innovation of the electromagnet and the telegraph in the beforehand 1800s, and became even an ext widespread v the invention of the phone call in 1876. Today, copper electrical connectors room still offered in telecommunications, and power generation, distribution, and also transmission.

Why is copper used for most electric wiring?

All metals have some lot of resistivity to electrical currents, i m sorry is why they require a power source to press the present through. The lower the level the resistivity, the much more electrical conductivity a metal has. Copper has low resistivity, and therefore is fantastic conductor.

Copper is also less oxidative than other metals. Oxidation happens once the oxygen and also moisture in the air react through a metal’s surface. This reaction corrodes the metal and produces a film-like covering, choose rust top top steel. Copper does not rust, but will develop a greenish patina dubbed copper oxide. Unlike rust, however, this extending actually protects the metal from more corrosion and also doesn’t interfere through conductivity.

How walk aluminum wiring to compare to copper?

While aluminum have the right to be offered for electrical needs, copper is better in a variety of ways. Because that one, aluminum has actually lower conductivity 보다 copper, and also is also much more prone come oxidation. The aluminum oxide that forms on the surface is no conductive like copper oxide, which means it will certainly interfere v the circulation of electricity. In order to combat this oxidation, aluminum have to be spanned with one anti-oxidant cream.

There can also be safety issues with aluminum electric connectors. Aluminum expands and contracts together it heats and also cools, therefore aluminum wiring deserve to loosen end time, creating a fire hazard. This safety worries can it is in mitigated, yet doing so needs special considerations, such as special fixtures designed for aluminum wiring, Arc fault Interrupters, and also “pig-tailing” copper cable to the ends of aluminum wires. In contrast, copper wiring is much safer to use, with fewer required precautions.

What are some best practices for copper electric connectors?

Even though copper has fewer safety worries than aluminum, all electrical energy is dangerous. While working on a wiring project, be certain to follow proper safety precautions.

When making use of copper electrical conductors, make certain to:

Use the exactly copper cable connector for the size and number of wires you’re connecting.Only use UL (Underwriters Laboratories) provided electrical connectors.Make certain wire ends are totally covered by the connector. Electric tape is not a safe different for spanning exposed wire.When connecting wires that have previously to be connected, the ends might be damaged. Trim the ends and re-strip the insulation to ensure the safest connection possible.Once you’ve finished, test that the connection is for sure by tenderness tugging ~ above the wires.
