What precautions should be taken to avoid the overloading of domestic electric circuits ?

To avoid the overloading of domestic electric circuits, the following precautions should be taken :

(i) Coating on the wires used in the circuit must be with good insulating materials like PVC, etc.

(ii) The circuit must be divided into different sections and a safety fuse or MCB must be used in each section.

(iii) High power appliances or too many appliances like air-conditioner, refrigerator, a water heater, etc. should not be used in a single line, i.e. from a single output.
