What’S The Difference Between Spt1 And Spt2 Wire? 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 is SPT1 vs SPT2? The bottom line, the only difference between the two SPT numbers is the thickness of the insulation. SPT-2 has 50% thicker insulation than SPT-1. It does not change the maximum amount of power the wire can handle.
What is SPT1 wire? “SPT-1” basically, is a standard to specify insulation thickness of the cord. The insulation, of course, protects us from being “shocked” by the electrically charged wires inside the lamp cord. Insulation thickness provides varying degrees of resistance to heat and abrasion.
What gauge is Christmas light wire? 18-gauge
The most common wire used for Christmas lighting is 18-gauge, which is rated for 10 amps. This means that both wire types use 10 amps regardless of the insulation. The only thing that will directly affect the amperage is the length of the wire being used.
What’S The Difference Between Spt1 And Spt2 Wire? – Related Questions
What kind of wire is in Christmas lights?
They come in two sizes (C7 and C9), two insulation ratings (SPT1 and SPT2), and four colors. Christmas light sockets come in two sizes — C7 and C9, so named for the most common bulb types used in each.

What is VW 1wire?
VW-1 is a vertical flame rating that measures the resistance of insulating materials to the propagation of a fire. The test involves mounting lengths of wire vertically in a ventilated chamber and attempting to ignite the wire with a gas flame.
Can you use lamp wire for Christmas lights?
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. SPT-2 is usually reserved for year-round lighting, such as patio lights, and has an insullation thickness of .
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.
Why are there 3 wires on Christmas lights?
The string of light is designed to daisy chain. The end of one can plug into the start of the next one. The lights are in series between the neutral at one end and the hot at the other end. Thus three wires – hot, neutral, and the series lights.
Can I use 18 gauge wire for lights?
The 18-gauge wire inside a lamp cord is rated for a maximum current draw of about 5 amps. That’s more than enough for a typical 120-volt lightbulb — or even several of them. If the same bulb runs on 12-volt power, however, you should upgrade the cord to 16- or even 14-gauge to avoid voltage drops and dim lights.
How many mini Christmas lights can be on a circuit?
For example, say a string of small LED lights only uses 12 watts. So you could, put 105 strings of those lights on a single circuit (1440÷12=105). However, a single circuit could only take 11 strings of large, incandescent bulbs that use 125 watts (1440÷125=11.5).
How many strings of lights can you safely connect?
Therefore, your circuit can only handle 14 incandescent light strings connected together. On the other hand, if an average LED string light set uses 10 watts, then 1440/10=144. That means you can have 144 light strings connected together if they’re LED! That’s a lot more light than the incandescent.
How many volts is a 20 amp circuit?
120-volt
20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts.
What gauge wire do you use for a lamp?
Lamp and extension cords are usually 18 gauge, but if you’re not sure, strip the wire through the 14- or 16-gauge slot first.
How long can a lamp cord be?
The customary length is 6 feet, but you can use as much cord as you need to reach from the lamp to the receptacle. To figure out how much cord to buy, calculate the length of the cord (including cord that is hidden in the lamp), and add 1 foot for attachments to socket and plug and for slack.
How long should a floor lamp cord be?
We recommend 8 Foot Cords to Wire Table Lamps and 10 Ft or Longer for Floor Lamps. The Shortest a Swag Lamp Cord Can Be is 15 Feet Long and when Routed Through the Chain Must Extend at Least One Foot Beyond the End of the Chain.

What does the so stand for in so cord?
Extra Hard Service
The “S” in “SO” stands for “Extra Hard Service.” This means that the wire is able to be used in applications requiring 600 volts or less. The second letter, “O” stands for “Oil Resistant,” which means the outer jacket of the cable is oil resistant.
