UL SUBJECT 98B
Outline of Investigation for Enclosed and Dead-front Switches for use in Photovoltaic Systems - Issue 3
Organization:
UL - UL
Year: 2015
Abstract: These requirements cover open, enclosed and dead-front switches rated up to 1500 V dc, intended for use in dc photovoltaic (PV) systems and installed in accordance with Article 690 of the National Electrical Code, ANSI/NFPA-70. These switches are intended for ambient conditions between minus 20 to +50°C.
These requirements are intended to be used in conjunction with requirements in the Standard for Enclosed and Dead-Front Switches, UL 98, except as modified or supplemented by the following requirements.
Unless otherwise specified, when the term switch is used in this outline, it refers to a photovoltaic, enclosed, open, or dead-front switch.
Fusible switches are intended for use with photovoltaic (PV) fuses which comply with the requirements of Outline for Low-Voltage Fuses – Fuses for Photovoltaic Systems, UL 2579.
These requirements also apply to open type switches, used in conjunction with the Outline of Investigation for Open Type Switches, UL 98A.
These requirements also cover fused and unfused electrically tripped PV switches.
These requirements are intended to be used in conjunction with requirements in the Standard for Enclosed and Dead-Front Switches, UL 98, except as modified or supplemented by the following requirements.
Unless otherwise specified, when the term switch is used in this outline, it refers to a photovoltaic, enclosed, open, or dead-front switch.
