Page 10: Sps Wiring
SPS Wiring: 6.1 DC Wiring: It is recommended in all cases to use stranded copper wires. Use SGX cross-linked polyurethane insulation type that complies with the high temperature insulation requirements (125°C.) of SAE J-1127 and vehicle manufacturer requirements. Wire gauge recommendations are minimum. For higher temperature rated, applications inside engine spaces or large motor loads and other applications with high surge currents use wire gauge 1 to 2 sizes larger than shown on table I. -
