We are using 120V commercial grade electronic ballasts, properly grounded, rated at 2Amps to drive two low pressure UV lamps submerged in water rated at 800mA. System requirements are to use GFI barkers with each ballast. This installation in a wastewater treatment plant, where there are motors, pumps and air compressors. GFI’s are randomly tripping at 5mA from ballast electronic current leakage up to 9.2mA. Can we resolve our nuisance GFI tripping by using 120V to 120V isolation transformers between the GFI and electronic ballast?
