Please note: All interim revisions for this edition available at time of your purchase will be included.
1.1 These requirements cover ground-fault circuit-interrupters intended for use only in alternating-current circuits wherein one of the wires is grounded in accordancewith the National Electrical Code. These devices are intended for use on 120 Vac or 120/240 Vac, 60 Hz circuits.
1.2 These requirements do not cover ground-fault circuit-interrupters intended for use in circuits served by a transformer having windings wholly insulated from eachother.
1.3 A ground-fault circuit-interrupter as covered by these requirements is a device whose function is to interrupt the electric circuit to the load when a fault current toground exceeds some predetermined value that is less than that required to operate the overcurrent protective device of the supply circuit.
1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, andthat involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements tomaintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflictwith specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformancewith the methods employed for development, revision, and implementation of this standard.
