Copper Wire Properties Gauge Conversions Values presented here are standards available for many independent publications, but ultimately they all originate from the American Wire Gauge (AWG) system (also aka the Brown and Sharp gauge).

Copper is a reddish metal that occurs naturally in rock, soil, water, sediment, and air. Its unique chemical and physical properties have made it one of the most commercially important metals. Since copper is easily shaped or molded, it is commonly used to make money, electrical wiring.

Marine wire quality is important and our marine grade wire is designed specifically to survive the harsh marine environment. Our boat wire is fine stranded copper (Type III stranding) with each strand completely tin plated so tinned copper will resist corrosion and ensure safe and secure operation for many years to come.

The simple explanation is that every color used for electrical wiring has a specific meaning, with different colors indicating different circuit types and purposes. Electrical contractors and electricians understand the color codes, but a simple guide can help you understand their significance.

In its nearly pure state, copper is a reddishorange metal known for its high thermal and electrical conductivity. It is commonly used to produce a wide variety of products, including electrical wire, cooking pots and pans, pipes and tubes, automobile radiators, and many others.

Instead of the standard copper wire, many houses built in the 1960s and early 1970s have aluminum wiring, which is considered a safety hazard. "Aluminum wiring connections often loosen up over time," says Greg Fletcher, a master electrician, educator, and author of several books on wiring.

When shopping for electrical cable and wire, you'll frequently see THHN, which is commonly used in residential building projects. In addition, most will be made of copper wire due to its conductivity.

What it means: You have a type of wiring, used in the 1960s and '70s as a cheap substitute for copper, that is no longer considered safe. Code violation? No; grandfathered in. Danger level: High. Aluminum corrodes when in contact with copper, so connections loosen, which can lead to arcing and fires.

Copper is predominately used in residential construction with the exception of the service cable and single purpose highamperage circuits such as subpanels, electrical ranges or air conditioners. Since copper is a better conductor than aluminum, the aluminum wire must be larger to safely carry the same current as copper.

Splicing wire connectors, such as twiston wire connectors, are not suitable for splicing aluminum conductors or copperclad aluminum to copper conductors unless it is so stated and marked as such on the unit container or an information sheet supplied with the unit container.

Black electrical wire is used for power in all circuits. Any circuit's black wire should be considered hot or live. Black wire is never used for a ground or neutral wire and should be used as the power feed for a switch or an outlet.

Take an Electrical Inventory – Make a list of all the appliances/devices you will be using in the house – and where. Your new electrical system must match the needs of the . Your new electrical system must match the needs of the .

How to make proper safe electrical wiring splices connections: This article answers basic questions about how splices (connections between two or more electrical wires) are made to connect secure electrical wires together in residential or commercial building electrical wiring systems.

THHN building wire is appropriate for use in alternating current (AC) electrical distribution systems of almost every industrial, residential and commercial building, usually at .

It is exceedingly unusual for copper wiring to become corroded, since copper is the most resistant type of wire to corrosion. So if you suspect that you have wires which are corroded, then you should check and make sure that the wires are not aluminum, rather than copper.

There are several problems with this aluminum and copper wiring method. One problem is that the two dissimilar metals are mixing together on a device. One problem is that the two dissimilar metals are mixing together on a device.
