When it comes to electrical wiring, knowing how to determine the right wire size is an important skill for any home handyman or professional electrician. It can be the difference between a successful electrical run and a failure that costs time and money. It is important to know the basics of voltage, current, and amperage when considering the wire size for an electrical run. It is also wise to take into consideration the environment where the wire will be placed, such as outdoors or indoors, and the type of insulation used.

For some, the thought of figuring out the correct wire size for an electrical run can seem daunting. But with a few basic concepts, it’s not so hard. The first step is to understand the fundamentals behind calculating electrical currents and the differences between amps, volts, and watts. Once you have a handle on these basics, you can then move on to looking at the different types of wire and what their insulation means for your project. From there, you can use a variety of formulas to accurately calculate the right wire size for your electrical run.
