Transparent Gold SPT-1 Lamp Cord Sets nicely harmonize with brass and gold colored lighting. Standard insulated 18 gauge wire has 2 parallel copper wires. The positive/hot is smooth, neutral/negative - has ribs. U.L. Listed for table & floor lamps were cord is exposed. Stripped, copper-tipped ends simplify wrapping wire around socket screws. Molded-on plugs are polarized and permanently attached to lamp cord. SPT-1 rating has traditional plastic insulation, see below.
The SPT thickness-rating provides varying degrees of resistance to heat and abrasion. Higher SPT rating numbers provide more resistance to abrasion and more protection from electric shock.
This store was fantastic for the parts I was searching for.
