To choose stabilizer capacity, first check the rating of the appliance in watts, VA, or kVA, and then consider the starting current if the load uses a motor or compressor. This is especially important for AC stabilizer and refrigerator stabilizer selection. You should also review the voltage fluctuation range at the installation site, because a unit with the correct capacity but the wrong correction range may not give proper protection. If one stabilizer is intended for multiple appliances, the total connected load must be calculated before selection.
