Boston THHN/THWN stranded electrical wire delivers reliable performance for residential and light commercial wiring applications. This AWG 12/7 conductor (3.5mm²) features a durable white insulation jacket rated for indoor use and general-purpose circuits. Each 150-meter roll provides ample length for typical installation projects, reducing the need for multiple spools. The stranded construction offers superior flexibility compared to solid wire, making it easier to route through conduit and tight spaces. Suitable for branch circuits, lighting, and outlet installations where code-compliant, temperature-resistant insulation is required. THHN/THWN rating ensures compatibility with standard electrical systems and building standards.
