Switchboard Wire is most often referred to in the electrical industry as simply SIS wire. It is also at times called out by electricians and end users as UL3173. SIS wire, although simple in construction, is a very versatile cable used in many different applications. Some of those applications range from its obvious name, switchboard wiring, to panel wiring, distribution boards, industrial control panels and many other applications up to 600 volts.
The construction of UL3173 is fairly simple and the wire is available in a large number of gauge sizes ranging from 4/0 to 18AWG. It usually consists of a stranded copper conductor that is tin coated with cross-linked polyethylene (XLP) insulation.
SIS wire is that it is rated at 90 Celsius as standard. It meets the VW-1 (Vertical Flame test) rating.
