Abstract—Many essential appliances like air conditioners and refrigerators which run in our offices and homes draw a heavy starting current. When the main power resumes or turned ‘ON’ suddenly, all the loads are switched ‘ON’ at a time and a very heavy initial current is drawn from mains. The current drawn is so high that other equipments are affected. The valuable home appliances can be ruined for such an incident. Sometimes it causes short circuit effect and fire due to extensive heat. The switching system described in this paper switches ‘ON’ the loads sequentially with a steady time delay to avoid the limiting inrush current in this odd condition. Also we have shown a way to control the switching system by a remote control system. Finally, this kind of switching system can be an important tool to save the electrical home appliances from damage due to unwanted or irregular ON-OFF of the main power.
Index Terms—sequential power ‘ON’, remote control, counter, flip-flop, relay switch
