Another question about installing a converter

Thinking all the wires heading to the different components can be 12awg or 14awg.

Actually if you are going to use a junction block to pull accessories from then I'd use 10g from the batteries to (+) & (-) input on the converter and 10g for (+) junction block & (-) grounding block. For example I'd wire the accessory plug/cigar type for the full 30a, (thinking of mine if I upgrade to the 30a converter,) using 10g. I'd run the lights @ 12g, radio @ 14g, etc. as needed.

gsf35099, here is the general rule of thumb for wire gauge. 14 AWG for 15 amp draw or less, 12 AWG for 20 amp draw or less, 10 AWG for 30 amp draw or less. You can run the 10 AWG wire to power the converter and then follow the list I posted depending on what the draw is of the component being powered. If you pull all items off 1 wire then add the amp draws together to get that size. I hope I have done a good job of explaining this.

Just make sure that wire will not be larger then 10g and fuse it at no more then 25a since that's your peak amp output, even though the wire can handle 30a.

Thanks, this definitely helps. The plan is to run the items through their own wires. I like the idea of putting a bus on after the output and then pulling from there to all the different items. I can run 10awg to the converter and 10awg to the bus and then the other gauge wires needed to each item.

I was thinking that it would be a good idea to place a 25amp fuse between the converter and the bus I plan to install. Thanks for the advice.
