The difference in insulation thickness has contributed to a few misconceptions about SPT-1 and SPT-2 wire. The biggest misconception has to do with amperage. Many think that because the insulation is thicker, SPT-2 wire can handle higher amperage than SPT-1. In fact, a lot of sites state that SPT-1 wire is rated for 7 amps and SPT-2 wire is rated for 10 amps. This is not true. Insulation thickness does not determine the amperage, wire gauge does. 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. As shown in the table below, the amperage decreases as the length of 18-gauge wire increases.
Another misconception is that SPT-1 wire won't last in harsh weather due to having thinner insulation. This is also not true. SPT-1 wire holds up well in most conditions when used seasonally (90 days or less). It is used in a variety of climates ranging from warm and tropical to cold and snowy.
There are two instances when SPT-2 wire is preferred. The first is when your lights are used for an outdoor display that will be up longer than the standard 90 day season. The thicker insulation provides better protection against long term UV light exposure from the sun. The second instance is when the wire is being used in extremely cold climates. Ice and cold can drastically affect all electrical cords, even heavy-duty ones, so having a little extra insulation won't hurt.
Ultimately, the choice between using SPT-1 or SPT-2 wire comes down to personal preference. Many customers choose SPT-1 wire simply because it's the most popular, easiest to find, and tends to be a little less expensive. Others prefer SPT-2 wire because of the thicker insulation. Once you do make your choice, be sure that your sockets and plugs have the same SPT rating. Otherwise, they won't fit on the wire.
