Where to buy 6/2 AWG tinned wire?

Load data indicates 6 AWG wire and my tape measure indicates I need 36 feet, but rounding up to 40 makes sense to me. The usual sources have prepackaged 50 foot lengths (plus 25' and several longer) at $2.72 for that length. Is that as good as it gets, or are there local sources that sell by the foot? West Marine only lists 18 AWG.

6/2 or 6/3 is expensive stuff. When I put in my inverter last winter, it cost me $260 for a 50 foot roll of Ancor 6/3.

Genuinedealz.com, my go to place for tinned marine wire and cable is sold out of 16/2 cable. Batterycables.com does have individual red and black 16 gauge cables for $1.34/ft each, or $2.68 for the pair. See https://www.batterycablesusa.com/tin...battery-cables

Where to buy 6/2 AWG tinned wire?

You're not going to find 6/2 duplex cable. It stops at 8 AWG if I'm not mistaken. You'll have to go with wire only. Defender and Genuinedealz.com is pretty hard to beat for wire price and they have it in stock. I assume it's for 12 volts here. If it's for a 120/240 vac, you need double insulated (like the triplex wire in a plastic shielding) unless the wires are in some sort of conduit or electrical box.

Edit: actually I just did a quick search and they do make the #6 duplex and triplex (Ancor wire)

Sorry, yes, this is 12 VDC power for my dinghy davit motor.

Ebay has boat wire.

Type in "6/2 boat wire".

Why would you need three conductors for an inverter install?

Dozens of suppliers withing seconds of Google search.

Might need or want 6/3 for a sub panel on the A/C side.

The 6/3 was for the AC side. So hot, neutral, ground from the panel to the inverter input and from the output back to the panel.

With the supply chain problems today, I would buy it wherever you are able to find it in stock. I have had to order some wire in one place and the rest in another since I couldnít find it in stock in one place.

I use Gregís Marine cable supply - very fast turn around, good quality US made cables, cheap shipping, available by the foot. Their cable lugs are also decent quality but cheaper than Ancor. Web site shows 6/2 tinned marine cable at $2.84/ft.

#12 wire would have been sufficient for 120 volts AC.

Hi folks. It's a DC load. I am powering my dinghy davit motor from the main DC panel. The ABYC 10% drop table says 10 AWG, the manufacturer says 6 AWG "just because." 8 AWG feels like the right answer despite my thread starting with a search for 6 AWG.

Yes, I am seeing that. Yikes!

Not sure 12 ga is suitable for any circuit above 30A.... so feeding the main or sub panel 6 ga may be more appropriate.

Otherwise shore power coeds could just be 12 ga.

But seeing it's DC for the OP.... 6/3 would only be needed/desired if going to a 3 wire motor.

Not when it needs to pass an entire 50 amp service leg through it. That requires 8ga minimum. I went to 6 for voltage drop and because part of the run is through the engine room, so adding the engine space de-rate put me very close to the limit for 8ga.



10ga would be fine for a 30a leg in most cases, however. Generally 30 amp shore cords use 10ga, 50 amp ones use 6ga (hence the extra cost and weight).

12 gauge wire is suitable for 20 amps. A typical branch circuit in a boat will use 12 gauge wire or in some cases. 14 gauge (suitable for 15 amps).

20 amps at 120 volts AC is pretty much a practical limit for an inverter on a boat. Anything higher would require an enormous battery bank to operate, even for a short time.

A 30 amp shore power cord is typically made from 10 gauge wire. 10 gauge wire is suitable for 30 amps.

Clearly I did not understand your original post. Please disregard all my comments.

My too small inverter/charger is a pass through 30A inverter/charger.

And I just have a little 40 footer. Some have much larger boats here,. I haven't looked into it, but don't some inverters have the capability to be used in series and put out huge loads.... well above my 30A.
