Miniature circuit breaker (MCB) —A compact mechanical switching device capable of making, carrying and breaking currents under normal circuit conditions and also making and carrying currents for specified times and automatically breaking currents under specified abnormal circuit conditions, such as those of overload and short circuits.

Residual current operated circuit breaker without integral overcurrent protection (RCCB) — A residual current operated circuit breaker not designed to perform the functions ofprotection against overload and/or short-circuits.
NOTE — Similar function is provided by earth leakage circuit breaker (ELCB).

An electrical inspection will ensure your home’s installed electrical components are in good working conditions and do not pose a hazard to yourself or your family.

To understand the various electrical loopholes that are left by contractors, it is extremely important and necessary to carryout electrical testing.

Many homeowners ignore the precautionary measures that have been detailed in different governmental policies, for different electrical installations.

There are many reasons behind the necessity of getting an electrical testing done. Some of the most common ones are:

• Protection against possible surges: This is a common phenomenon in different regions, especially when there is a storm. Electrical surges can not only ruin your appliances, but can also create short circuits in your house. When the testing is being done, the auditor will check for different points in the wiring that can cause this type of mishap.
• Fire: Many a times it has been seen that an electrical short circuit has been the reason behind a fire breakout in a house. These short circuits are caused by different loose wires in the meter or in the cabling itself. During the testing, the auditor can easily recognize these faults and ask you to rectify them.
• Shocks: Imagine touching an electronic appliance and immediately experiencing a surging electric current in your body. Although the impact may not be that disastrous; however, this could lead to other mishaps easily. Apart from this, the body current in an electronic appliance can easily hamper its performance or can render it completely non-workable. An electrical auditor can catch these faults in the wiring in time to rectify them.

The maximum interval between periodic verifications may be recommended for guidance in the Regulatory Measures Relating to Electrical Safety and Supply under the Electricity Act, 2003 . As per recommendations Testing requires :

When purchasing a home.

When occupancy of a house has changed.

When adding an appliance.

When a home has had a major renovation.
