Wire & Cable

Wire & Cable – Electrical Conductors for Power Systems

The wire and cable category provides comprehensive electrical conductors for all aspects of solar power installations, from high-current battery connections to control wiring and grounding. Quality wire features appropriate insulation ratings, conductor sizing for ampacity requirements, and durable construction that ensures safe, efficient power transmission throughout system lifespan. Modern electrical wire meets NEC (National Electric Code) standards with proper temperature ratings, voltage classifications, and environmental resistance for indoor and outdoor applications.

Wire options include THHN/THWN building wire for conduit installations, flexible welding cable for battery interconnections, bare copper wire for grounding applications, and multi-conductor cable for control circuits. AWG (American Wire Gauge) sizes range from small 18AWG for signal wiring to heavy 4/0AWG and larger for high-current inverter and battery connections. Insulation colors include standard black, red, white, and green for proper circuit identification and code compliance.

Cable assemblies include pre-terminated battery cables with ring terminals, extension cords for temporary power, and multi-conductor bundles for simplified installations. Specialized cables accommodate high-voltage DC applications with appropriate insulation ratings exceeding 600V. Stranded conductors provide flexibility for routing through tight spaces, while solid conductors serve permanent fixed installations.

Wire selection considers circuit ampacity requirements, voltage drop calculations, installation method (conduit versus cable tray), temperature ratings, and environmental exposure conditions.
