When using either a converter or a battery charger, make sure that they are connected
in parallel between the battery and the refrigerator. Do not use a converter or battery
charger to supply the DC power directly to the refrigerator because these two devices
do not supply filtered DC power (See Art01521).
As the distance from the vehicle battery to the refrigerator increases, the correct AWG
wire size also increases. If he wire size is too small for the distance, a voltage drop
occurs. The voltage drop decreases the cooling performance of the refrigerator.
1. Norcold recommends that you use the following wire and fuse sizes:
- Measure the distance from the vehicle battery to the refrigerator:
- If the distance is less than 12 feet, use 16 AWG wire and a 10 Amp fuse.
- If the distance is between 12 and 20 feet, use 14 AWG wire and a 10 Amp fuse.
- If the distance is more than 20 feet, use 12 AWG wire and a 10 Amp fuse.
- Twist the lead wires to reduce the radio interference and induction of a high voltage
surge from the outside (See Art01518A).
