SB6100 INDUSTRIAL SHOCK-BLOCK™ TECHNICAL FAQ
■UL 943 Standard applies to Class A, single- and three-phase, Ground-Fault Circuit-Interrupters (GFCI) intended for protection of personnel, for use only in grounded neutral systems in accordance with the National Electrical Code (NEC), ANSI/NFPA 70, the Canadian Electrical Code, C22.1 (CEC), and Electrical Installations (Use), NOM-001-SEDE. These devices are intended for use on alternating current (AC) circuits of 120 V, 208Y/120 V, 120/240 V, 127 V, or 220Y/127 V, 60 Hz circuits.
■UL 943C requirements cover ground-fault circuit-interrupters intended for use in one of the following applications:
▲On grounded-neutral systems where voltage to ground is above 150Vac and equipment grounding or double insulation is required by the NEC®, ANSI and NFPA 70
▲On grounded-neutral systems where voltage to ground is 150 Vac or less and equipment grounding or double insulation is provided, but the use of a Class A ground-fault circuit interrupter is not practical
