Is solid or stranded wire better?

There is no clear-cut answer to whether a solid or stranded wire is better. The appropriate choice varies depending on your intended application. However, it is important to note that a solid wire is a better electrical conductor. It also provides lofty, steady electrical features over an extensive range of frequencies.

Due to its solid nature, it is jagged and more likely to withstand corrosion and vibration. In spite of all these features, it is not always advisable to settle for a solid core wire. This type of electrical wire is not always the better option. There are several considerations when it comes to choosing the better option between a solid and stranded wire.

A solid cableconsists of a single strand whereas a stranded one comprises several thin wires twisted into a bundle. Each of them has various distinctive advantages depending on your specific application details. A stranded wire is ideal for applications that require constant winding and cable twisting. It works better in intricate applications such as circuit board wiring due to its flexibility

On the other hand, a solid wire is ideal for outdoor wiring and heavy-duty applications. This type of cable is durable even under the worst conditions and more compact compared to stranded wires. The smaller surface area of a solid-type wire doesn’t negate its current carrying capacity. For example, the current-carrying capacity of a 22 gauge solid wire is equivalent to that of a stranded wire of the same size.

I am sure that at one point or another, we have all come across the phrase ‘shortcut is always dangerous’. I can confidently say that that phrase is applicable in this particular case. Any attempt to mix a solid wireand a stranded wire is can be equated to taking shortcuts. Why do I think so?

Well, the only reason you might want to mix them is that you ran out of cable and you have an extra one but it is not exactly similar to the former. You also might have run out of stranded cable and you want to finish up the remaining part of the project with a cheaper solid cable.

It is possible to mix a solid and a stranded wirebut that does not necessarily mean that you should do it. Connecting a solid copper wireto a stranded wire is a relatively complex process. There is a significant chance that something may go wrong. When dealing with electricity, a slight mistake may cause huge damages. So, why should you take that risk?

The best way to avoid the temptation of mixing wires is to ensure that you purchase the right length of cable. For instance, if you settle for an 18 gauge solid wire, you must ensure that its length is sufficient to serve your wiring needs completely. Electrical cable manufacturers, suppliers and retailers often sell cables per meter. It is best to consult a wiring expert concerning the exact wire length for your project.
