Stranded, Parallel, Thermoplastic
SPT is an abbreviation for Stranded, Parallel, Thermoplastic, a designation found on most flat wire. This abbreviation is always followed by a number denoting the insulation thickness. Despite what many believe, insulation thickness is the only difference between SPT-1 and SPT-2 wire.
What does SPT-1 and SPT-2 mean?
In a nutshell, the difference between SPT-1 and SPT-2 is the thickness of the insulation. SPT-1 is . 03” and SPT-2 is . 045”. That’s the only difference physically between the two ratings.
What’s the difference between SPT-1 and SPT-2?
The main difference between SPT-1 and SPT-2 electrical cord is in the thickness of insulation. SPT-1 gives you insulation that’s 0.03″ thick while SPT-2 is 0.045″. With 50% thicker insulation, SPT-2 is the Wire of choice for anything that is reaching close to 7-amps. Both SPT-1 and SPT-2 have the same maximum amperage.
