Can you tap into wiring to a lighting circuit? Most are protected by a 15 amp fuse, so use #14 wire.
Okay now that I am digging around, ^this^ got me thinking with an 'ahh ha'!
The Furion radio/dvd player is in the wall console under the TV and right where I want the socket.
Can I just tap into that 12v line with a wire run of less than two feet? Its a 15a fuse.
I guess I should check the radio manual to see how many amps it draws first?
It doesn’t necessarily mean it’s the proper way to do it or rated properly, but this is exactly what I did in our old trailer...tapped into the radio power wire to install USB jack nearby. New trailer has a ton of USB jacks...I guess that’s a premium addition to trailers now.
Okay great & thanks!
Just bought THIS little socket with a built in power switch.
Going to take the radio out tomorrow and see whats what.
The manual isnt really specific on how much 12v power draw.
I lists "4x24 W RMS" which is 24w for each of the 4 speakers max, I assume.
If that's right then 24x4= 96w max
96 watts / 12 volts = 8 amps (there is a 10a blade fuse on the radio itself)
8a radio + 6a (2x 3a USB jacks) is 11 amps.
15 amp fuse at the power panel and hopefully this set up should be good to go.
