Power chords stuck together

[Monaramblee]

Using a 30 amp adapter chord attached to my rvs 50 amp chord i occasionally here some crackling noise where they meet. Tried unplugging the adapter and it will not seperate. It seems like one of the legs might be welded ? Any thoughts on how to seperate them without damaging the rvs 50 amp chord?
I dont care about the 30 amp adapter chord.

Put a quality end on your dog bone.

Ok if thats true then no hockey puck for me......

Hi,

The "hockey puck" adapters are far more likely to over heat and melt.

Deoxit ok will do thanks.
So far i have priced out a 50 to 30 adapter at $39....not sure if all these adapters come as a dog bone but if possible i would love it as one solid piece.
Heres the thing, i have the adapter attached to a 30 amp ext cord with the c clamp. At most campgrounds i would prefer to eliminate the 30 amp extension which means plugging the adapter into the park pedestal ( wont be able to use the c clamp) so i will for sure require a new adapter.

Follow up... while waiting for the new plug to come in i was able to remove the plug from the adapter! Plugged it back in and it still would not go in all the way, plugged it into a spare 30 amp adapter and it seated perfectly. Turned breaker on, no crackling, prong does not look burnt or damaged so i cancelled the new plug order.

Get some Deoxit. Use it from time to time. Monitor voltage, too.

Start watching for a good price on a male and female plug. You may wish to salvage the burnt adapter.

Noticed one more thing. The replacement 30 amp adapter wishbone which is also old, would not make a tight connection to the 30 amp cord and would crackle when i touch it. I put a c clamp on it to make a tight connection and will order a new 30 amp adapter.

Im guessing the 30 amp adapter is toast.

As rule i do turn the breaker off but i cant say for sure that once or twice i may not have. I will buy the plug then pry the existing plugs apart and see what i find before cutting the head off.

good plan. I was going to suggest that the first beheading be on the cheaper cord and see if that can solve part of the problem.

If the voltage is low and the amperage is high, it may happen again. Even if you use deoxit.

Depends on what caused it to happen the first time. It should not have. I have been RVing now for 14 years and it has never happened to me. If you don't find and fix the cause, it very well may. My guess is that you had the breaker on, and a high current draw item like a water heater or converter on in the RV. You plugged in the adapter, THEN you plugged the power cord into the adaptor. Or you unplugged the power cord from the adaptor under those conditions. That caused a spark that welded them together. Always turn the pedestal breaker off when plugging in or unplugging.

And, those grease applications may, or may not, prevent it.

I just use Deoxit D-5....works great. I also use an Autoformer so voltage is always good.

Dexoxit is a better choice than di-electric grease. Naolox is a good choice as well. Di-electric is a non conductor but works great in wet or exposed locations.
