I'm wondering if the existing 12v heating element wire going to my old Dometic is of sufficient gauge to support a compressor fridge.
You can search "diameter of conductor" and find tables with diameters of about any conductor"
10 ga 2.59mm; 12ga 2.05mm; 14ga 1.63mm (going to vary minimally depending on stranding)
My dometic RM8805 had a 120W 12V heating element so at nominal 12V approximately 10A, mine had 12ga stranded conductor
My Domectic CRX 110 replacement with a Danfoss DB35 draws less than 4A
