I use the 30A plug on my MH. OR do I have to get a 20-30A converter and plug into the 30A plug to test the circuit.
Thanks in advance.
Not all parks have 50 amp service, or if they do, they may not have it at all the sites.
You may also find out, that not every park has their pedestals wired the same way.
probably, the best thing to do since you have a 30 amp trailer, is to get the 30 amp male-15 amp female adapter cord you talked about. Then you can test all the 30 amp outlets with the 12-4058.
The following link tells how to make up an outlet tester using an analog gauge and a circuit tester. Since you have the 12-4058 that combines the circuit tester and gauge into one, you only need it.

Personally, I have both setups. I have one like in the link to test the outlets at the campgrounds before plugging in (I bought this first).....and have a 12-4058 (bought later) that I keep plugged in to an outlet inside the trailer so I can see at a glance if the voltage is dropping.
If something happened to my first setup, I could always use the second in it's place if needed.
