How are standard wires labeled or identified for their gauge and other specifications?

Standard wires are typically labeled or identified using a combination of markings and color codes. Here are the common methods used for identifying the gauge and other specifications of standard wires form Standard Wires And Plugs Supply:

Voltage Rating: Wires are often marked with their voltage rating, which indicates the maximum voltage they can safely handle. Common voltage ratings for standard household wiring include 300V and 600V.

Temperature Ratings: Wires may have temperature ratings specified on their labeling. This indicates the maximum temperature at which the wire can operate safely without the risk of insulation damage. Common temperature ratings include 60°C, 75°C, and 90°C.

Insulation Type: The type of insulation material used on the wire may also be identified. Common insulation materials include PVC (Polyvinyl Chloride), THHN (Thermoplastic High Heat-resistant Nylon), and XHHW (Cross-Linked Polyethylene High-Heat-resistant Water-resistant).

Sequential Markings: In some cases, wires may have sequential markings printed along their length. These markings help with identification during installation and troubleshooting.

Bundling Information: Wires that are meant to be bundled together for a specific application, such as in ethernet cables or cable harnesses, may have identification labels indicating their purpose or function within the bundle.

Compliance Labels: Wires and cables that meet specific industry standards or certifications may display relevant labels or logos indicating compliance. These could include certifications like UL (Underwriters Laboratories) or CSA (Canadian Standards Association).
