Inverter wire size?
So new to this, I'm wanting to connect a 425 watt inverter in my rig. What would be the minimum wire size to use for the 12 volt connection?

I=425/12=35.4 AMPS
10G wire is rated 30amps.
I would go with #8
Add 10 percent for converter loss and overhead So the "rule of thumb" i use is figure AC watts / 10 volts
For that inverter I'd use standard automotive battery cables (4GA) for runs up to around 5-8 feet.. Longer runs bigger wire.. I'd not go shorter.
One Edit.. I said I would.. I also DID. When I had an inverter in that size class.
