Wiring

Make sure you are using the right wire for the job. We offer UV resistant direct burial, TECK, and multi-strand welding cable to suit each application.

The table below indicates the maximum run length (in feet) of a wire size for a given maximum load current for a 12 VDC system limited to a 5 % voltage loss. Multiply the distance shown by 2 for 24 V systems, by 4 for 48 V systems.
