Lot many appliances like airconditioners and refrigerators run in our offices and homes. And almost all of us must have noticed the momentary dimming of the lights when these loads draw a heavy starting current. The current drawn is so high that other equipment are affected. When all the loads are switched on, very heavy initial current is drawn from the mains.

The sequential power-' on' circuit presented here switches on the loads one after the other with a regular time delay to avoid the limiting inrush current, especially after mains power resumes. It is designed for switching on 16 appliances with power-' on' reset facility.
