Question

Overloading occurs when

• A. very few electrical appliances are used causing rise in currents.
• B. many heavy electrical appliances are simultaneously used each drawing large currents and increasing overall load.
• C. Appliances working beyond their rated values, hence causing heating.
• D. failure of fault indicators, hence causing overloading.

Answer 1

Answer: (B)

many heavy electrical appliances are simultaneously used each drawing large currents and increasing overall load.

When many heavily rated electrical appliances are used together, each of them draws high currents. The sum of these currents is supplied from the power distribution system. The sum of currents being very high poses a threat to fault in the system. This is known as overloading.
