5 Core Cable Markings for 2nd

Understanding cable markings is crucial for electricians and anyone working with electrical systems. Here are five core cable markings you should know:

• Color Coding: Each core (wire) within a cable typically has a distinct color, indicating its function. Common colors include black (hot), white (neutral), green (ground), and red or blue for additional circuits.
• Numbering System: Cables often have numbers printed on the insulation to identify individual cores. This is especially helpful in multi-core cables where color coding alone might be insufficient.
• Voltage Rating: The voltage rating indicates the maximum voltage the cable can safely handle. This information is essential for selecting the appropriate cable for a given application.
• Amperage Rating: The amperage rating specifies the maximum current the cable can carry without overheating. It's crucial to ensure the cable's amperage rating meets or exceeds the load it will be carrying.
• Manufacturer's Markings: Cable manufacturers often include their logo, brand name, and other identifying information on the insulation. This helps verify the cable's origin and quality.
