1. Norcold recommends that you use the following wire sizes:
- Measure the distance from the vehicle battery to the refrigerator:
- If the distance is less than 19 feet, use 14 AWG wire on DC 12 volt series or 16 AWG
on DC 24 volt series.
- If the distance is between 19 and 32 feet, use 12 AWG wire on DC 12 volt series or
14 AWG on DC 24 volt series.
- If the distance is more than 32 feet, use 10 AWG wire on DC 12 volt series or 12
AWG on DC 24 volt series.
NOTE: It is not recommended to locate the refrigerator more than 32 feet from the
battery.
- Twist the lead wires to reduce the radio interference and induction of a high voltage surge
from the outside (See Art01518).
2. On MRFT60 models only, install a 15 Amp fuse in the DC wiring circuit near the battery to
protect the refrigerator against reverse polarity or a short circuit.
