Hi all

I am installing 2 x dual power points (sample in link below) side by side and seeking expertise / assistance to know how the wiring configuration should occur between the terminals to ensure good operation on all four sockets and not shorts

With 4 + terminals and 4 (-) ones is it a simple matter of linking all the +'s then all the -'s in series then back to power source or something different?

I already have a fused power cord coming from the fuse box

Any help greatly appreciated to ensure I get it right ?

Join the positives to the positives and the negatives to the negatives and they will be in PARALLEL, not series. And wired correctly.

Thanks John and Regina

So use some of those dual pronged connectors.... leap from one to the next to the next all in a row for each... + & - yeah?

Hey WMS,

To my understanding, there should be only 4 prongs? 2 x positive and 2 x negative?
Because with one 12v socket there is 2 prongs?

Not sure? What wiring has it got at the back?

Cheers Misha

Thanks Misha,

I am installing 2 of these units so 4 sockets with 2 prongs each...

Hi WMS, there should be no problem doing as you suggested in all 4 +'s together and then all 4 -'s together with the fuse as close to the battery as you can. I prefer to solder the wire to the pins rather than use clips. If you are not looking for marine grade you can buy a 4 socket set with only wiring to the battery to be done.

The only comment I would make is make sure the supply cable coming from the battery, which is fused at the battery end, is of sufficient size to carry the anticipated current. I would then fuse each outlet seperately to avoid overload per socket.

Thanks Cookie

These are wired back to the fuse box on a joint circuit with water pump, lights on a 25amp fuse.... it was one socket and I have made it 4.... I am can put in on a separate spare circuit available, upgrade wire to 6mm and if you think needed, fuse it with its own 25amp fuse if that sounds right?

I would put 10A fuses in, as this will protect the wire supplying the lot

Ok thanks... I was going to wire all 4 sockets into a common circuit... or should I split them into 2 circuits on 10amp fuses each?

Firstly if you expect to draw anything near full rated out of these sockets, you need to fuse them indivudually.

That makes wiring them a little more complicated.

If you intend to draw no more than total rated of one outlet for the group a single fuse would be OK.

now that aside.

The best way I have come up with to split an incomming supply and negative return is.

come in in a 6mm2 supply feed crimp a 6mm2 non insulated joiner onto the end of that cable....take 4 x 1.5mm2 tails strip them and cosnolidate the strands by twisting....carefully and neatly....trim the end and present this up to the other opening in the joiner & crimp.....now you won't get the insulation butted up nice...but don't be too concerned as long as it is neat.

cover in glue lined heat shrink.

You can do similar with different combinations as long as the multiples crosssection fits the lug.

But ya got no fuses.

possibly the easiest thing for merer mortals without a full electrical tool kit is

Go and buy a small fuse box with a common positive feed and built in in negative common..and wire to this.

Blue sea and bainbridge have more or less the same nice little box.


resst the urge to dasy chain and definitely do no solder diretly to that type of socket.

cheers
