What is Type SIS wire?
In the electrical industry, switchboard wire is often referred to as SIS wire. This particular type of lead wire is available in a number of different gauge sizes. It features a solid or stranded tinned copper conductor and cross-linked XLPE insulation.
Is Sis wire tray rated?
With the ability to be dual rated, SIS Wires meet the standards of UL 3173, UL 3195, UL 3196, or XHHW-2 depending on the gauge size.
What is TFF wire?
TFF. Same as T2 wire but stranded, 140°F. TFN. Heat Resistant Thermoplastic covered fixture wire of solid or seven strands.

What is thermoplastic covered fixture wire type TF?
TF wire is a type of wiring covered in a thermo-formed plastic material. This wire is commonly utilized in appliances and electrical devices. Supplying a wide range of voltages, this wire comes in two primary gauges, designed for a variety of applications. Thermoplastic wires are found in a variety of applications.
What is switchboard cable?
SIS is commonly referred to as Switchboard or Panelboard wire. It is a building wire product made of an insulated copper conductor – usually tin coated – with thermoset, cross-linked polyethylene (XLPE) insulation. The insulation properties of SIS are the same as XHHW-2.
What is TFFN & Thhn wire?
The initials in the name of THHN Wire stands for Thermoplastic High Heat Resistant Nylon while those of TFFN Wire stands for Thermoplastic Flexible Fixture Nylon. Also, the TFFN wire can be used for branch circuits while the THHN wire can be used for control circuits and machine tools.
