What gauge is SPT-2 wire?
18 gauge
Both SPT-1 wire and SPT-2 wire are made using 18 gauge copper wire at their core. The difference is that SPT2 has a thicker insulation around the wire. Thereby making it slightly larger around than SPT1 and giving it the ability to carry a slightly higher electrical load.
What does SPT-2 wire mean?
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. SPT-2 wire is noticeably thicker, with a thickness of 0.045 inches.
What’s the difference between SPT-1 and SPT-2 wire?
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.
What does SPT-1 and SPT-2 mean?
The difference between SPT-1 and SPT-2 wire is the thickness of the insulation surrounding the copper wire. SPT-1 wire has a thinner insulation than SPT-2. 18/2, SPT-1 wire has an insulation thickness of . 030″ and 18/2, SPT-2 has insulation that is . 045″ thick.
What does SPT wire stand for?
Page 1. Flat Wire: SPT: Stranded, Parallel, Thermoplastic This is always followed by a -1, -2 or -3, signifying insulation thickness for different applications.
Can you use lamp wire for Christmas lights?
Plain wire is the commonly used wired for custom lighting. Plain lamp wire is offered in two options, both use 18-guage copper. SPT-1 is typically used on Christmas lights, and has an insullation thickness of . 03 mm and is rated for 7amps.
What does 18 2 wire look like?
When a wire is labeled as 18-2, it means that it is 18-gauge thickness (AWG) with 2-conductors (inner wires). You can generally swap out 18-gauge wire with slightly thicker or thinner wire. They may find that the thinner wires are easier to connect.
How big are C9 light bulbs?
C9 bulbs are Lit Professional Lighting’s light of choice. They still maintain the shape of C6, and C7 lights, but are the largest yet. They are 1 ¼” round and 2.5” tall, a full inch taller than the C7.
