The size of cable used for a 1 ton AC depends on various factors such as voltage, current, and distance.

• The cable size is determined by the current rating of the AC unit.

• For a 1 ton AC, the current rating is typically around 5-7 amps.

• The cable size can be calculated using the current carrying capacity of the cable and the voltage drop considerations.

• Factors like the distance between the AC unit and the power source als...read more

The size of cable is selected based on factors like current carrying capacity, voltage drop, and environmental conditions.

• Consider the current carrying capacity of the cable, which depends on the load and the type of cable.

• Calculate the voltage drop to ensure it is within acceptable limits.

• Take into account the environmental conditions such as temperature, moisture, and chemical exposure.

• Refer to relevant standards and...read more

Different types of Earthings include: protective earthing, functional earthing, system earthing, and lightning earthing.

• Protective earthing is used to prevent electric shock and ensure safety.

• Functional earthing is used to provide a reference potential for electrical equipment.

• System earthing is used to stabilize voltage levels and protect against faults.

• Lightning earthing is used to protect structures from lightning s...read more

Earthing is a process of connecting electrical equipment to the ground to prevent electric shock and protect against electrical faults.

• Earthing is done by connecting the electrical equipment to a conductive material, such as a metal rod, buried in the ground.

• The purpose of earthing is to provide a path for the flow of excess electrical current to the ground, preventing damage to the equipment and ensuring safety.

• Earthi...read more
