Editing Refrigerators (section)

==== Wiring ====
The existing 12-volt circuit running to the refrigerator compartment of a GMC is 12 awg wire, capable of sustaining 10 amps over a 16-foot run. A Norcold N8DC pulls considerably less than that; for peace of mind, this circuit can be fused at 10 amps without issue. If you're going the route of running a dedicated inverter to power a 120 volt compressor fridge, you may find that your compartment is already supplied with a 120 volt AC circuit; a larger inverter can supply that circuit, or you can run dedicated 10 gauge 12 volt wiring to the refrigerator compartment; 25 amps can power a 300-watt AC inverter, providing enough power to run some apartment-size refrigerator models.
