SPT wire is used for lamps, small appliances, radios, fans, clocks, and Christmas lights
SPT wire is a portable cable used for household appliances and light-duty applications. SPT stands for Stranded, Parallel, Thermoplastic, a designation found on most flat wire. It is also referred to as a lamp cord or cable and is commonly used for radios, fans, clocks, and Christmas lights. SPT wire is easily recognisable due to its variety of common uses and can be found in most households.
There are two types of SPT wire: SPT-1 and SPT-2. The key difference between the two is the thickness of their insulation. SPT-1 has an insulation thickness of 0.3 inches, while SPT-2 has a thickness of 0.45 inches. This means that SPT-2 has better protection and is more suitable for harsh weather conditions and long-term outdoor use. The thicker insulation of SPT-2 provides better protection against UV light exposure and is ideal for lower-temperature applications. On the other hand, SPT-1 has thinner insulation, making it more pliable and environmentally friendly due to its lower carbon footprint.
When choosing between SPT-1 and SPT-2 wire for Christmas lights, there are a few things to consider. Firstly, SPT-1 is the most popular choice as it is easier to find and tends to be more affordable. It is suitable for seasonal use of 90 days or less and can be used in a variety of climates. SPT-2, on the other hand, is preferred for outdoor displays lasting longer than 90 days, as the thicker insulation provides better protection against UV light exposure. It is also recommended for extremely cold climates, as the extra insulation protects against the impact of ice and cold on electrical cords.
It is important to note that the maximum amperage load is determined by the amount of copper in the wire and the length of the wire being used, rather than the insulation thickness. Both SPT-1 and SPT-2 wires can handle the same amount of power, and the length of the wire will directly affect the amperage. Therefore, when choosing between the two types of SPT wire, it ultimately comes down to personal preference and the specific requirements of your project.

SPT-1 and SPT-2 differ in insulation thickness, with SPT-1 at 0.03 and SPT-2 at 0.045
SPT stands for Stranded, Parallel, Thermoplastic, a designation found on most flat wire. SPT wire is a portable cable meant for household appliances and light-duty applications. It is commonly used for radios, fans, clocks, extension cords, and Christmas holiday lighting decorations.
SPT-1 and SPT-2 differ in insulation thickness, with SPT-1 at 0.03 inches and SPT-2 at 0.045 inches. SPT-2 wire has 50% thicker insulation compared to SPT-1. This thicker insulation provides better protection against long-term UV light exposure from the sun and is therefore ideal for outdoor use. SPT-2 is also recommended for use in extremely cold climates as the cold can drastically affect electrical cords.
Despite the difference in insulation thickness, the power handling does not change between the two wire types. The maximum amperage load is determined by the amount of copper in the wire and the length of the cord being used, not the amount of insulation. SPT-1 holds up well in most conditions, including seasonal Christmas lighting and decorating installations. However, in extremely cold climates, SPT-2 wire with its thicker insulation may be preferred.
SPT-1 wire is more affordable and easier to find, making it a popular choice for many. SPT-2 wire, on the other hand, is more expensive due to its thicker insulation. When choosing between SPT-1 and SPT-2, consider factors such as budget, climate conditions, and intended duration of outdoor use.

SPT-2 is ideal for outdoor use and extreme cold due to its thicker insulation
SPT stands for Stranded, Parallel, Thermoplastic, a designation found on most flat wire. SPT wire is a portable cable meant for household appliances and light-duty applications. It is commonly used for radios, fans, clocks, extension cords, and Christmas holiday lighting decorations.
SPT-2 wire has 50% thicker insulation compared to SPT-1 wire. SPT-1 wire has an insulation thickness of 0.3 inches, while SPT-2 has a thickness of 0.45 inches. This thicker insulation makes SPT-2 ideal for outdoor use and extreme cold.
In outdoor settings, SPT-2 wire is more durable than SPT-1. The sun's UV rays can cause the insulation of an SPT-1 wire to become brittle and break over time. SPT-2 wire, with its thicker insulation, is better protected from the sun's UV rays and will last longer outdoors. This makes it a good choice for outdoor light decorations.
SPT-2 wire is also preferred in extremely cold climates. Ice and cold can affect all electrical cords, even heavy-duty ones. The thicker insulation of SPT-2 provides better protection in these conditions. For example, in places like Alaska, Canada, and other far north areas, SPT-2 wire would be a good choice.
While SPT-1 wire is more popular, easier to find, and less expensive, SPT-2 wire is a good option for those who want thicker insulation. This thicker insulation does not change the maximum amount of power the wire can handle but provides better protection in harsh weather conditions.

SPT-1 is more popular and cheaper, but SPT-2 has a higher environmental impact
SPT stands for Stranded, Parallel, Thermoplastic, a designation found on most flat wire. SPT wire is a portable cable meant for household appliances and light-duty applications. It is commonly used for radios, fans, clocks, extension cords, and Christmas lighting decorations.
The main difference between SPT-1 and SPT-2 wire is the thickness of their insulation. SPT-1 has an insulation thickness of 0.03", while SPT-2 has a thickness of 0.045", making it 50% thicker. This thicker insulation on the SPT-2 wire provides better protection against long-term UV light exposure and is recommended for lower-temperature applications. SPT-1, on the other hand, has thinner insulation, making it more pliable and suitable for most conditions.
SPT-1 is the most popular option and tends to be cheaper than SPT-2. It is widely available and used by many customers due to its ease of accessibility and affordability. However, SPT-2 is preferred in certain situations, such as outdoor displays lasting longer than the standard 90-day holiday lighting season or in extremely cold climates for better protection against the elements.
Despite the differences in insulation thickness, it is important to note that both SPT-1 and SPT-2 have the same maximum amperage load. The misconception that thicker insulation results in a higher maximum amperage load is not accurate. The maximum amperage load depends on the amount of copper in the wire and the length of the cord being used. Therefore, SPT-1 and SPT-2 have the same power handling capabilities.
In terms of environmental impact, SPT-1 is considered more environmentally friendly due to its lower carbon footprint. The thinner insulation on SPT-1 requires less material, resulting in a reduced environmental impact during production and use.
