8 Gauge Wire

Got 25' of red and black 8 gauge copper wire, a 40 amp breaker and some lugs. I plan on wiring this truck correctly for the 12v frig. I hate to admit I never wired the three previous trucks correctly and the frig never worked right.

  • Assuming that you do it to factory fridge - I have been thinking about this, but too many dilemmas like :
    1. with heavy cables supplying 150 amp to deeply discharged camper batteries you can blow them up.
    2. 12 v refrigerator elements are lower output. Maybe adequate where you camp, but I camp in 110+ F and full fridge output is crucial.
    3. My truck has factory 400W inverter and I was thinking about running 120 v wire, but making it safe is whole new gimmick
    4. propane use for fridge is minimal, while it still cools better than 120V (although by small margin)
    So why bother, spend money and have additional risk/hassle, when it works pretty good?
  • So why didn't they work before and what are you doing different this time?
