I posted some info on the 18th oct regarding of wiring 12v sockets and a usb socket to my battery via a 4 way bladed fuse box in my campervan which i succeeded. But now all sockets are live as the USB sockets blue light is on so I've just disconnected the positive wire to the battery. Does this mean my sockets would use power if I leave pos wire connected? My other ? is can i isolate them by placing a switch between the fuse box and the battery? hope someone can help.

Regards David.

The light in the USB sockats will be an LED and will be drawing 2/3 of 8/8 of stuff all, but if it worries you ..of course you can put a switch between the fuse and the sockat.

Beautiful Ross, all done connected all to a on/off 20amp rated switch, connected both the 12v cig soc's positive wires to a female connector then connected to male on blade fuse box and replaced 10amp fuse with a 20 amp. The USB soc I just fitted on/off switch and all is working well . Thanx again for your knowledge and help.

Although the LED will use very little the USB 5v regulator may use more in it's "at rest state" not absolutely sure. I would, as Bantam said, place a switch in the line to the usb device so it can be turned off if you want the other plugs to be live or as he mentioned switch the lot off.
