This time the AC worked well. Don't know if the problem was the
circuit breaker or not, but at least we kept cool this time.

We stayed at the American Heritage RV park, which is a nice place to
stay if you're ever in that neck of the woods.

Tom or Dick, if either of you happen to read this, last year one of
you suggested an instrument for testing the current at camp sites. I
didn't get it then, but want it now. Could you remind me again what it
was, please?

The only way I know how to do it is to use a multi-meter to check for
120 volts (on a 240 system) against neutral and ground.

Ommmmmmmmm....

It is a digital volt meter that plugs into the receptacle. And will
also tell polarity, and most likely if you have a ground.



Polarity?


Yup, polarity. Is the Hot lead on the correct receptacle terminal. Is
the Neutral on the correct terminal. And do you have a ground wire
attached.

That's not just any run of the mill DVM.

See, I remembered some of my electronics.

That's only if you want to blow something up.

And always cut the red wire - not the blue wire. Occasionally the
green wire. :)

The meter I saw at Camping World yesterday was digital and it measured
voltage and frequency and checked polarity. It also had an audible alarm
if voltage or frequency went out of range or if polarity was wrong. It
plugs into a 110 15A jack. Plug into a power post and learn if it is
safe to plug in your camper. Then put the tester in an outlet inside the
camper to continuously monitor the power.

I still have some reading to do, but why only 15A if the trailer is a
30A?

My point was that not "any" DVM is going to do all that.
