Best dog bone?

Conntek #15370 (30A male to 50A female)



http://www.conntek.com/products.asp?id=1135

I don't recall the brand, but the one I bought at Walmart has worked for me for several years with no signs of damage so far. We spend a lot of time at 30 amp only state parks, so it gets a lot of use.

My Shepard X's preferred the femur :)

I want something that isn't going to melt prematurely

Are the blades on your plug blackened?

The only way the plugs melt is if the plug blades are causing resistance.

Take something as simple as an emery board and sand down those blades until they all shine bright gold. THAT stops plugs from melting.

I saw somewhere (on the internet) where someone used the "pulls" (like the one Old-biscuit posted) to secure the dog bone to the pedestal. So that's what I'm going to look for when I'm in the market again!

I agree that the heat problem is from resistance and the brand will not matter. Cleaning the plug blades is helpful but the outlet is often the problem. Since folks just yank out their plugs without turning off the electricity, the outlets are burned. I insert and remove the plug a number of times before use in an effort to wipe the contacts.

Not yet, I don't have one ;)
But we're getting a new TT that's 50A and the years of RVing has taught us to buy the best stuff first.
I bought the Conntek - got a good deal on fleabay.

Thanks everyone!

Make sure it is UL/CSA listed instead of some unknown piece of !@#$ quality. Last time I was at a CW they had a shelf full of pigtail adapters that were non-listed. I would say Marinco/Park Power is as good as they get. Make sure when you plug into a pedestal the power is always shut off.

Thanks all!

Depending on the price of pre-fab ones, I'd be tempted to make one.

Not just from being cheap (which I am...) but I suspect the 30A male plug isn't going to last long, for the reasons others mentioned above. I'd rather replace an end, than scrap an entire dogbone.

When plugging in at a campground, I try to avoid plugging my shore tie (30A, molded male plug, coach end permanently connected) into the 30A female campground receptacle. If I can, I use a 50 to 30 dogbone that I've replaced the female with a box that has a pedestal-style receptacle in it. The molded female 30's are JUNK. Bad enough that the pedestal and the shore tie male get trashed, but the molded females are the WORST. Their contacts go bad easily then the male hot blade overheats and starts its toll on that plug.
