I bought some Seadog 12v power sockets for my tent trailer and want to wire them up safely AND economically. I've read about fire conditions when running an inverter for long periods but I plan on only charging and powering USB devices. Is this type of 10/2 cable sufficient for 3 outlets?

What amp in-line fuse would be the best protection in case somebody did plug in a high draw item? Is that determined by the wires rating?
Thanks for any assistance.

#10 is heavy enough for 30 amp but the fuse should be rated no more than the amp rating of the socket or the connecting lugs. With stranded wire you have to be carefull that ALL the strands are inside a crimp lug.

I checked the specs on that wire and it is copper and therefore good for the application.
A lot of the "Landscape wire" is made of steel and not suitable.

Most outlets we use in our business are rated at 15 amps which is plenty for usb type charging devices. That wire is fine for the purpose. I use it for my solar panels.

Do you need 250'  With just 60C insulation don't go any bigger than 30a fuse.
I recommend some actual wire made for this pupose.
10/2 boat wire 25' $26.25 shipped
For a short piece you can have 8/2 for $1.77 per foot shipped and just get what you need.
This stuff has 105C insulation so you can fuse it like normal primary wire.

Thanks for the input folks. The sockets are rated at 24V, 16A, max. Each one should have its own feed and fuse I would imagine. Is 15A too much fuse if max rating is 16A?

I am not sure about what wire is being discussed.....but.....
wire has INSULATION covering it...the insulation is rated
for voltage........most common wire insulation is rated
for 600 volts, and is used in 'house wiring' where the
maximum voltage between two adjacent wires is about 320
volts (115 volts x 1.4 for peak x 2 for adjacent wiring
at opposite polarity at any instant).....SOME wiring,
such as thermocouple wiring has VERY LOW voltage rating.
I have seen thermocouple wire, newly attached to a wall,
burn like fireworks when first energized to supply
a refrigerator at 120 volts. Be sure your
insulation is properly rated.
