Replacing 30amp male plug

The male end of my 30amp plug is kinda Burnt from being plugged into a 110 extension. It looks like replacing the male end of cord is pretty straight forward. Any precautions I should take first? I'm wondering is there any stored power I need to be aware of when I open the plug.
  • Phone them before you go. Or check with their web sites. I'd start with West Marine (pricey) and check Home Depot.

    In the meantime, clean up the existing plug with sand paper or an emery board. Spray it with antioxidant. If all you have is WD-40 use that sparingly.

    Walmart stocks the dog bone connectors.

    I do carry a spare male and a spare female 30 amp plug.

Which store do you think I'll have the best luck at. I'm on bicycle so I'm trying not to ride all around the island.

    I have always used the RV30A to 15A LONG DOGBONE type adapter like this one from WALMART...



    This type of adapter does let the pins of the 30A Male plug get hot.

    The small round type adapters like shown here are known to burn up your contacts and shouldn't be used...



    They will burn up your 30A Plug contacts everytime...


    Also if you are using an extension cord to get to your house/garage 120VAC receptacle use one that is 12GAUGE at a minimun. a 10GAUGE is even better. The cheap RED/ORANGE 14-16Gauge cords from WALMART doesn't do well...

    I lucked out in my garage where I had a 20A Circuit where an Air Compressor was once used. Nothing else is on this 20AMP Circuit breaker in the power panel.

    I found a couple of 50-foot contractor grade 10-gauge Extension Cords at a yard sale for my hookups.

    I also use one of these RV 120VAC plug in meters inside the trailer where I can glance at it. It has the SAFE ZONES printed on the scale. I won't turn on my air conditioner if the Ac Voltage is out of safe limits...

    And if the inlet gets over loaded, arcs and "burned" will it be easy to find in a small resort town?

    I think cutting the cord is a good idea. But leave a four foot pig tail and put on a standard male three prong 30 amp RV plug. Then install a female plug on the remaining cord.

  • Easy to do. I replaced mine a few years ago when the cord started to break at the connector.
  • I use a "Camco 55242-30 amp. I think its the easiest to wire. An outlet is what it plugs into. Also the more connections you have the more likely your to have a loose one. MOHo

    No stored power. Just ensure you wire the common and hot correct and the lugs are tight. You may want to consider installing an inlet and using a detachable cord. This allows you to carry a spare in the event one is damaged.


    I'm not sure what an inlet is. It sounds like a good idea to have a plug that can be replaced.
