Wiring Tips

  • Use the correct size cable for the plug/socket - most standard plugs will accept up to a 4mm auto cable easily.
  • The 12-pin flat plug have a second row of 5 larger points which will accept up to 6mm auto cable.
  • For best results, do NOT run battery charge lines, or fridge power lines through a 7-pin or 12-pin plug. The cable size that you are limited to by the plug/socket, are simply too small to carry enough current (amperage) to either charge batteries effectively, or run your fridge effectively. Use Anderson plugs and a minimum of 8 B&S cable for such requirements.
