Q6: How much bigger does an aluminum wire have to be to carry the same current as a copper wire? A: Aluminum wire typically needs to be larger in cross-sectional area compared to copper wire to carry the same current due to aluminum’s higher resistivity. This helps determine the current the cable will carry when the connected load is at its maximum. Q5: How do you calculate full load current of a cable? A: Full load current of a cable can be calculated using the formula: Full Load Current (FLC) = Load in Watts / (Voltage x Power Factor). Instead, adhere to standards and codes that provide specific guidelines for calculating the current carrying capacity of cables based on various factors. Q4: What is the thumb rule for current carrying capacity of cable? A: Thumb rules are not recommended for accurate electrical calculations. Electrical codes and standards provide guidelines for determining load capacity. Q3: What is the load capacity of 2 core Aluminium cable? A: The load capacity of a 2-core aluminum cable depends on factors such as the cable size, conductor material, insulation type, and installation conditions. The capacity is typically determined by electrical codes and standards, and it’s important to consult these references for accurate values. Q2: What is the carrying capacity of aluminum wire? A: The carrying capacity of aluminum wire depends on various factors, including the cable size, temperature, and insulation type. Standards and formulas like those provided by the National Electrical Code (NEC) are used to determine the safe current capacity. Q1: How do you calculate the current carrying capacity of an aluminum cable? A: The current carrying capacity of an aluminum cable is calculated based on factors such as the cable size (cross-sectional area), material properties, insulation type, ambient temperature, and installation conditions.
