To select the correct wire, you must first determine its application and calculate the required amperage. Based on the amperage, choose the appropriate wire gauge (AWG) using NEC tables, accounting for voltage drop on longer runs. Next, select a conductor material (copper for reliability, aluminum for cost) and an insulation type with the right temperature and environmental resistance (e.g., wet, oil, or sunlight resistant). Following these steps ensures a safe and code-compliant installation. If you are unsure, please call us and we'll help.
The difference between solid and stranded wire is in their construction. Solid wire uses a single, rigid conductor, making it less expensive and ideal for fixed installations like in-wall building wiring. Stranded wire is composed of multiple small strands, making it highly flexible, durable against vibration and bending, and more expensive. It is best suited for applications that require movement, such as appliance cords and automotive wiring.
No, not all wire requires a UL or CSA listing, but it is a critical requirement for a vast majority of applications. While not a universal requirement for every single type of wire, a UL or CSA listing is the industry standard for safety and is a legal requirement for almost any wire used in a permanent electrical installation in the U.S. and Canada.
Before starting any wiring project, you should always contact your local city or county building department. They can provide you with a copy of the specific electrical codes they enforce and guide you through the required permitting and inspection process. Failing to follow these local rules can lead to significant issues, including a failed inspection, costly rework, or, most importantly, serious safety hazards.
Once you determine the required amperage, you can select the correct wire gauge (AWG). The National Electrical Code (NEC) tables (e.g., Table 310.16) provide the minimum wire size for a specific amperage, with a lower AWG number indicating a thicker wire. For longer wire runs, it is essential to use a larger gauge than required for amperage alone to prevent voltage drop, which ensures that the equipment receives sufficient voltage to operate efficiently.
