KB's AC drives are designed to operate with ground fault circuit interrupters (GFCIs) which are required by the National Electrical Code in locations where electrical products may contact water. KB's drives contain special software allowing them to operate on GFCI circuits without tripping, which is a standard feature on digital drives and optional on AC hybrid drives. This allows KB drives to operate equipment used near water like boat lifts, food processing equipment, and portable tools plugged into GFCIs.
