If you need a higher temperature and performance wire, use crosslinked SXL wire instead. Available in 10 different solid colors: Red, Black, White, Green, Blue, Yellow, Brown, Orange, Purple, and Pink. Each copper wire core is composed of smaller gauge strands of pure copper creating high conductivity, flexibility, and durability. RoHS compliant and meets or exceeds SAE spec J1128 and J378. Ideal for wiring 12 volt or 24 volt electrical systems with a maximum voltage rating of 60 volts. Available in small bundles, and larger spools.
