Switchboard Wire & SIS Wiring

What is SIS Wire?

In the electrical industry, switchboard wire or panelboard wire is simply called sis wire. This particular type of lead wire is available in a number of different gauge sizes and features an insulated copper conductor, our particular sis wire can have an  annealed copper conductor. Usually, you will find sis wires being used in switchboards and panelboards specified by the National Electrical Code. The tough XLPE insulation lowers interference while keeping the sis wire flexible.
