Perhaps I am just too much overkill with my #4 battery cables, but in comparison those cables sure look small.
IMO #4 is too small.
1. Use the largest practical wire size.
2. Use the shortest practical wire length.
3. DO NOT coil up the excess wire; its a fire waiting to happen.

Looking for a Pure Sine Wave inverter to push my Samsung 22" TV and Mac Mini computer. Any suggestions? TV needs 45 Watts Mac Mini 85 Watts.
Where is the best place to get the DC power from? Directly from Battery? It would be nice to have it cut off like everything else with the battery disconnect.
Thanks for your help.
I have a small 100 watt inverter...for my tv/dvd. Permanently mounted.
I have it fused and a cutoff switch for the source dc to the inverter.
I have a master cutoff switch for my battery. The inverter is connected to it so if the master is off everything is off including the inverter. I only turn the switch on for the inverter when I need it.
I do have a nice small portable, Modified Sine wave, 75watt inverter that I use for my laptop. Plugs into a cigarette lighter. Used that for years...A Mac may not like a Modified Sine wave inverter so you might need a Pure Sine Wave, either way.
My laptop running on the inverter pulls about 4-4.5 amps max. That is max 54 watts dc...and about 60watts output from the inverter.
Thus not pushing it very much.
Some folks will run an inverter and wire it into the bottom or top socket of their Rigs 120vac system. I elected not to do that. I only wanted to run my tv/dvd/vcr....so I just ran an extension cord from the inverter to a small power strip near the tv and peripherals.
The installation instructions actually called for a 110 amp T style fuse, but all I could only find was a 100 amp fuse. For the wire size, amperage, and length of the wire run, 100 amps works.
