Does anyone know of a connector I can buy that I can have one 10awg wire on one end, and four 14awg wires on the other?
I want to use one 10 gauge wire to power four individual relays for accessories...

 

I think you would need to use all 10 gauge or all 14 gauge. I don't know of any connectors, short of something like a homemade fuse-box, that would allow 1 large in and 4 smaller out. I know you can buy 1 in-4 outs that are all the same size though. If you have a big wire coming in you need something to step it down and protect the smaller downstream wiring.

 

There are LOTS of connectors from Packard (I think today they call themselves Aptiv, who knows what it will be tomorrow) and Deutsch that offer connector shells that accommodate different sizes of wire. Just like OEM auto harnesses. Since of course, that's where those parts come from.

Vorteciroc might be an excellent resource in nailing down the parts etc. you need. You might have to settle for something somewaht generic like 2 #10s and more smaller ones, and only use however many, and plug the rest with seals.

 

Would this be out of the question?

 

Delphi (Aptiv) and Deutsch both have splice connectors that are basically a connector with a busbar inside, but I think they tend to be for smaller signal wires, not so much passing higher power. I really don't know all the options though so might be worth a look.

Deutsch has something called a "sealed bus bar" that is actually meant for passing power. Has a ring terminal for the large feed cable, and a connector for the breakouts.

What current draw is expected? 2 x 14 AWG is roughly equivalent to 10 AWG. So 4 x 14 AWG is double the size of 10 AWG. If it turns out you can use smaller wires then it's probably going to make it easier to find what you want.

 

I don't know what the total current draw would be. I just know there are 4×40 amp relays that are housed in a box with fuses. I need to bring power to them but don't want to run 4 individual wires from the battery (or starter lug in this case). Haven't yet found a way to bus all the connectors in the box together...

 

There are so many options....

Are 4 40A Circuits is the intended final use case?

 

At least 2 will be used, and the other 2 will be spares for possible future options. None of the circuits will pull 40 amps, but I don't yet know what the combined current draw will be...

 

I have an sealed Amphenal Buss that you connect to a Power Cable on a Junction Stud...

You can use it as:

-6x 25A Outputs.
-3x 50A Outputs.
-2x 50A + 2x 25A Outputs.
-2x 75A Outputs.

No matter what, total Amperage Output will be up to 150A.

I'm looking at Amphenol products and much of it looks shockingly familiar, and I am left wondering.... has TE ever invented anything on their own?

 

This is one instance where Deutsch is the original creator of the (DT/ DTP/ DTM) Products.

TE Later purchased Deutsch and improved/ expanded the Products.

Amphenol created copies, but they also further improved some of the design aspects and expanded the variety yet again.
(Deutsch does not offer the above products, but share the same Terminals DTP/ ATP).


But yes (you are correct) most of the time TE is either purchasing something or copying it.
