Need high-current 12VDC deck plug
I'm looking for a watertight deck plug to be used in the power line of my wind generator. I haven't been able to find anything in my web searches that looks suitable. Here are the requirements:

* water tight
* needs to be able to handle 4AWG wire
* needs to handle at least 20 amps current
* preferably installable without special purpose crimpers

The reason I want a plug instead of a continuous run from the wind generator to the voltage regulator is that I live in a hurricane zone and I want to be able to just unbolt the whole wind generator and tower and toss it in the back of the truck for hurricane prep. I sometimes have to do this several times a year. I don't want to have to deal with pulling wires every time a hurricane threatens.

Any ideas?

Thanks in advance!

Nothing specific to recommend, but I would look at connectors for trolling motors.

Aviation stuff is top notch. The implications of a failure are higher

I put a plug on mine that is just below the generator inside the pole. It is from a UPS. I placed it within the pigtail from the generator. I can bring the pole to horizontal and then remove the wind gen. The pole stays wire tied to the life lines thus reducing windage. : Buy 10PCS/lot 175A 600V SMH twin pole large current plug connector connector UPS plug storage battery charging plug low shipping from Reliable 175A 600V suppliers on HOBBY KING TECHNOLOGY LTD

A watertight connector capable of accepting 4AWG wire is going to be large and expensive. Look for watertight connectors in 75~100Amp range and see what I'm talking about. Those would be able to handle your wire size. 20A connectors are sized for much smaller wire (typically 12~10 ga.)

Your wind gen has a built in rectifier to put out 12v DC?

Yeah, 4WAG would be way overkill, 10-12 would be fine. I'd second the trolling motor connectors which are obviously able to handle 30-50 amps without an issue.

Trolling motor connectors or electric down rigger connectors. Both would work.

With 10AWG you can go 15 feet with only a 5% voltage drop on a 20amp draw.

With 8AWG you can go 25 feet with only 5.2% voltage drop with a 20 amp draw.

Send me a PM and I will forward along my automated excel wireloss worksheet. I use it all the time. Very handy.

I found one from Marinco called ConnectPro that handles 6AWG, and is supposed to handle 25A. I think that one will do. Thanks to all for the suggestions!

I'd suggest bringing the wires into the boat via two Scanstrut watertight deck glands, a pos & neg one, and terminate them at two BlueSea power posts or a dual pos/neg bus bar inside the boat.

This way you can use standard marine lugs. When you need to remove the wind gen just disconnect inside the boat and pull the wires through the deck glands. Two dowels the OD of your wire will seal the glands when the wires are pulled..
