    CQD: 5/25/2015

    After reading NEC 422.31 Appliance Disconnecting Means I hit a wall of confusion. How do you determine when an appliance has 300 Volt-Amperes? Example: An electric water with specification sheet showing 4,500 Watts … what are the calculations or steps one would take to determine Volt-Amperes? Thanks a million!
