12 Volt Outlets

Actually, there are 3 12v breakers from battery. I connected to breaker, 12ga to 15A fuse, 12ga to outlet. Protected by both breaker and fuse.

Almot.. I can not speak to his RV but in mine the power leads to the main fuse box can safely haul 80 amps, they are seriously THICK (Way bigger than 10 ga, closer to 4 or six ga) that is where he tapped in his 12ga.

NEVER hook a larger "Load" wire (The wire from the fuse box to the device) to a smaller "Supply" (The wires to the fuse box from the battery/converter) less you really love visits from firemen.

Examples

Battery==4ga====fuse==12ga GOOD

Battery--12ga----fuse---8ga BAD

Hi Almot,

I think he has by passed the 12 volt power distribution fuse box and gone directly to the main 12 volt breaker.

Installed a 12V power outlet, NOT a cheap "12v outlet". Installed on 12Ga wire, fused to main coach power circuit breaker. Use it for 400W inverter to power computer, Printer, phone charger, Nook charger, and just about anything I need. It is on a 15A fuse.

With #12 wire on the outlet, and thinner wire (#16?) throughout the rest of the rig, can anybody explain me how this would solve the problem?

One table top location I use one of these USB CELL PHONE type receptacles to be able to charge cell phones etc which is pretty neat...

Where did you get the dual USB outlet?

While travelling, 2 GPSs and a small inverter for the notebook computer. We use the notebook for the Silverleaf PC program and now have mapping and GPS to put in there. When dry camping, we use them for charging cellphones etc.

The supply wires were not adequate for small inverter so we had them upgraded to #10.

do you have to buy a plug that will fit that 12v outlet?

Only if you want to use it.

I power a laptop, a bunch of different chargers, a 3 watt cell phone amplifier, a WiFi Ranger router, a 300 watt inverter, and a Sony iPhone docking station.

Here is an example of our use while traveling with the DGKs. TVs, DSs, Ipods, nightlight in bathroom, laptops, cellphones, GPS and Dashcam. We have two inverters, one hard wired and one in a outlet.

Don't! They suck. Use the socket for stuff you would normally charge in your car/truck. Maybe a small inverter (definitely under 300 watts)

X2, they usually put REALLY thin wire on those and the sockets themselves are not rated to handle much power. They expect it to be used like one's in your car, for charging phones and such. Marinco does make a 15 amp socket and you could wire up some properly sized wire to that and run heavier duty devices from it like old 12V tube screen TV's.
