I have surplus of High Voltage Copper Insultaed DC cables with eye-round type connectors. Different length. Cables are rated for about 280-400V 150A from different Toyota Prius Hybrid Cars. Also copper bus-bars. Heaps.

 

Any use for EV DIY or Boaties? i.e. should I be bothered of listing those on Trademe or just dump at the scrap yard?

$6.8 clean copper more or less.

 

But if you try and buy that kind of cable online - you'll be looking at something like $25/ short pigtail.

Boats with electric bow thrusters or big anchor winches (typically at 12V, sometimes at 24V) always seem to be having issues with burnt out cables or switch gear. No idea if your cables would be the right length (often boats with bow thrusters will sometimes have a bow mounted battery or battery bank to avoid issues with long distance high current wiring runs), No idea how you would contact boaties looking for High current DC cables.

 

Would the cables be usefully for the DC wiring in a solar PV system?

Any idea of Gauge or mm size?

 

I've just finished wiring up an HD electric recovery winch. Had to purchase welding cable to do the job as standard auto gauges of DC cable were too light.

 

Try selling them on Trademe. They may be just what someone needs.

Got a photo? what sort of length range? looking to wire up a dual battery in the 4wd so possibly overkill but could work.

Maybe car audio.

 

I used to use welders flex in mine.

My Solar install is scheduled for the next week - I will be able to see what are they using...

Will check - I'll cut one and measure it.

Planning to measure all of them, make photos and a list.. From memory (was working on 15 Land Cruisers a while ago) - should be be perfect. And if length is OK, then no need to redo the end points..

I am another winch/dual battery installer who could be keen dependent on size and length and price.

 

 

 

Cheers

 

Matt.

Just observed what the Vector installers use: DC 4mm Square which are much smaller cables.

Boat cabling should be fully tinned (will eventually corrode internally otherwise). 

 

Bus bars should tinned for marine use also otherwise you can end up with corrosion between terminals and bar - which is a nuisance and on a negative bus can cause equipment failure due to voltage spikes.

Very busy lately - got to check just one - the shortest pigtail (#1). It is fully tinned.

 

Cable without insulation is 5mm diameter - but very flexible as it is multi-thread.

 

Other cables are longer than those #1.

Are these cables still available ?

 

Anything around 3 meters in length ?

 

For an electric start 50Hp outboard motor  ..

 

 

 

Cheers

Sorry for not updating the post. Did not have time to dig into boxes and compile a list of those.

 

Cables I have are less than 3 m. Would need junction boxes for that length. I do not know the maximum length, a meter maybe more or less.

 

In EVs like Leaf (2013) main cables going from on-board charger to the battery are short - 1/2 meter See on my video here: Nissan Leaf Charger - dismantling

 

In Prius/Camry hybrid two main wires which are going from Invertor to the battery in the back are the longest ones you can source from the wrecks.

 

They will still be less than 3 meters each. And I do not have those invertor-battery ones.

Finally got my hands on cables - all sorted on the floor. Will measure and make photos tonight. Design as in the photo above. Copper. Tinned. Isolated. Rated for 100A 500V. The length is different.

 

There are also few Automotive 125A 500V DC fuses with enclosure (made by Littelfuse Inc for Toyota):

Just be sure you are getting suitable cable.  Marine cable is supposed to meet requirements for tolerance of petroleum, heat and movement.   Permeability of the insulation to moisture is an importunate consideration as well.  They way the terminal have been crimped is important - ideally a compressive crimp, rather than a punch crimp.

 

IMHO it's worth buying certified marine cable. 

 

As an example the winch cable on my boat is 28 years old and still absolutely fine.  If I was to replace it all with certified marine cable it would cost me about $200.
