I have a timer system in place that takes in 120Vac as input power and i have it set up in a way to use it for my loads (water pumps). According to my specs my water pumps require 115V to operate. I notice there is a 5V difference in power being supplied and power requirements. So what happens? Will my pumps get damaged from excess power? My water pumps are submerged in my ponds when they are operating.
