I want to connect several 12 Volt sockets in parallel. On the positive side the wires are connected to a fuse box which is connected to the positive pole of a 12 Volt lead battery. How do I connect the negative wires? Is it okay to use ring terminals and put them on a single screw/nut?

1\$\begingroup\$ There's nothing wrong with your idea in principle. The implementation may be bad though. Could you add a photo, and also specify what current your fuses are for? \$\endgroup\$– Dmitry GrigoryevCommented Mar 18, 2016 at 8:52

\$\begingroup\$ That works, but if you ever have to make changes it is a pain. Probably better to use a dedicated distribution block. \$\endgroup\$– R DrastCommented Mar 18, 2016 at 10:26

\$\begingroup\$ @DmitryGrigoryev: I haven’t started the implementation yet. I plan to use 10 A fuses. \$\endgroup\$– Timothy B. RaleyCommented Mar 18, 2016 at 11:48

\$\begingroup\$ spade lugs might be easier to deal with if you have to make changes. but of course they won't hold as well as ring terminals if the system is moving. \$\endgroup\$– MikePCommented Mar 18, 2016 at 14:56

\$\begingroup\$ That is a fine way to do it. Just make sure you get a long enough screw ;) \$\endgroup\$– KilowattLaserCommented Mar 18, 2016 at 17:30

You could, but really, that's what terminal/distribution strips/bus/bar/blocks are for. And it's easier than a single screw + multiple lugs.
The last one is a car distribution/fuse box. Very convenient, especially with 10 Amp blade fuses being so common everywhere.
