Kábelméretek

Kábelméretek refers to the size or cross-sectional area of electrical wires, typically measured in square millimeters (mm²) or American Wire Gauge (AWG). The appropriate cable size is crucial for safe and efficient electrical installations. It depends on several factors, including the current the cable will carry, the length of the cable run, the type of insulation, and the ambient temperature.

Larger cable sizes have a lower resistance, which means they can carry more current without overheating. Using a cable that is too small for the intended load can lead to overheating, insulation damage, fire hazards, and voltage drop. Voltage drop occurs when the resistance of the cable causes a significant reduction in the voltage available at the end of the run.

Standards organizations, such as the International Electrotechnical Commission (IEC) and the National Electrical Code (NEC) in the US, provide tables and guidelines for selecting the correct cable size based on these parameters. For household wiring, common sizes might range from 1.5 mm² for lighting circuits to 2.5 mm² or higher for power outlets. Higher current applications, like those found in industrial settings or for large appliances, require significantly larger cable cross-sections. Understanding kábelméretek is essential for electricians and anyone involved in electrical work to ensure safety and proper functionality.
