This came in the boat, it is obviously an electric adapter but it does not fit my boats power inlet. What is it for? It is probably so simple and I'll look silly but here it is. MM

MM,
It look like a 125volt locking industrial adaptor, the spade end locks into a supply cord or outlet with a twist after installing and then an industrial extension cord or appliance is plugged into the other end. The dual spade is for both industrial and non-industrial (home) application. The 20 amp is it's max allowable load. PO may have used it to plug into shore power.

Any others want to enter in then please do so.
Bill.

Hmmm... the male end looks like a standard 30amp shore power connector with a 20amp female adapter at the other end.

Edit: the female end appears to be the type used for some RV shore power connections

I do not have my shore power cord available to compare again but my recollection is that the blades are closer to the center than the male end on my shore power cord. I may have only tried to plug it in to the female end of the cord. Is the male and female end of the cord the same pattern, or are they different? MM
 
Sfergson727 has it correct. I have borrowed one that is identical for a standard 110V high pressure washer and want to buy one but they cost about $50.
 
I have one and Sfergson727 is correct. If you don't need it list it on ebay. People will buy it.

Your shore power cord is 30 amp, that is why it is larger. If you have an outlet on your dock that is a 125V 20 amp twist lock, this is what you need to plug in your every day items like power tools, pressure washers, etc as mentioned above. We use them a lot in construction with portable generators and electric tools. I'm with Oldskool on this one.
 
Lots of the "Rag Boaters" in our marina use those so they can plug in their 110 cords. I walk down the dock all winter pulling them out of the water because they have abandoned them until spring :smt021
 
The problem is that the twist lock male end is only 20 amp. The PO probably had an outlet for maintenance at his dock and all receptacles on a dock should be twist lock to keep from disconnecting by accident and running the risk of the cord ending up in the water as Scott said. If you have no 20 amp twist lock receptacles I would just bring it home or give it away.

I thought Scott and I were saying the same thing. To be sure it is an adaptor from one type of outlet to another type of plug.
Am I saying that correct Scott or did I miss understand what you posted.
Thanks Mate.

That is it exactly. Part number is correct. Where would I need it? Why would someone need a locking connection and 5 inches later not need a lockin connection? MM

One example would be a small boat that does not have shore power built in like a small cuddy cabin yet it is being used in a slip that has shore power and the person has a electrical need like hatch air conditioning.

Yes, as long as the power source on the dock is 20 amp. Most are 30 amp, which would mean you need a bigger adaptor.
 
You need the locking connection so it matches the dockside connection. Besides, without the locking ability, the weight of the adapter and the extension cord would likely cause it to pull out. The extension cord is less likely to pull out by itself, and can more easily be wrapped up so it doesn't cause extra weight on the adapter. It's all about leverage - with the adapter locked, you're basically just plugging the cord into a fixed outlet (although it is really a "fixed" adapter). An "unlocked" adapter applies more leverage at the receptacle and would more easily fall out as compared to just a normal extension cord.

It is rated at 20amps because that is what the max rating for a typical extension cord would be.

I think we're all pretty much saying the same thing - just coming at it from different directions... to make it more confusing!

That is not a 30 amp pattern even though it appears that way in photos. It is a smaller pattern. Do some marinas have a 20 amp locking receptacle? MM

80A is the pattern of a standard 30 AMP shore power connector.
Try it again. Perhaps your prongs are slightly bent inward. Work at it a bit.
 
The 20A and 30A receptacles are different...they will fit by bending some prongs and crushing some plastic though! I moved slips this year to an older section that has old 20A power receptacles instead of 30A. I needed to buy an adapter that looks like the male end you have, and has a 30A female receptacle on the other. 20A adapter end to shore receptacle and my shore power plug to the 30A side of the adapter. I used a bungee cord to keep it in but have now purchased a dongle type (short cable between the two ends). Sometimes the shore power breaker trips if I try to operate the air conditioning and hot water tank at the same time. It always trips if I add the AC converter into the mix.

Wish I had known this before I moved...luckily I am usually only at the slip long enough to load up for the weekend!
