What precaution should be taken to avoid the overloading of domestic electric circuits?
✓
Answer
To avoid overloading of domestic electric circuits, the following precautions should be taken:
$(1)$ Wires used for carrying current should be of proper current rating.
$(2)$ Two separate circuits should be used, one of $5 \ A$ current for lighting electric bulbs, tubes, TV, etc. and another of $15 \ A$ for higher current rating appliances such as heating appliances, $AC$, etc.
$(3)$ Parallel circuits should be used and each circuit should have a fuse of proper rating.
$(4)$ Too many higher power rating electrical appliances such as electric iron, geyser, air-conditioner, etc. should not be switched on at the same time.
$(5)$ Too many electrical appliances should not be operated on a single socket simultaneously.
$(6)$ Wires should be replaced by new wires of proper rating and good insulation after every $5-6$ years.
$(7)$ $PVC$ of good quality should be used.
