It is hard for me to answer your questions because.. Well, somewhere in my life I picked up a piece of wall paper. It says that I know a thing or two about electronics.

Standard 50 amp outlet, Round hole at bottom

Side to top should show 120 volts, does not matter which side
Side to round also should show 120 volts, again does not matter
Side to side should show 240 volts

IF that is the case. pole is properly wired and NOT fake.

So, can you remember this?

I plug in my plug in surge guard, it tells me everything I need to know and 2-3 minutes later CLUNK I get power.

As for multi-meters, One beside me as I type, One in the work room, (Actually 2 in the work room) one brand new still on the card in a storage box, one not on the card in the storage box.

Like to make sure I have one handy don't you know.

Home is where I park it!

Using a portable EMS unit to "test" the pedestal first is NOT just as good as using a meter or a Power/Pedestal Tester.

If you have a 50 amp EMS unit and it passes 50 amps per leg, a total of 100 amps then the pedestal is wired correctly and you will have 12,000 watts of power to use.

If you have a 50 amp EMS unit and it only passes 50 amps for both legs then the pedestal is NOT correctly wired and you will only have 6000 watts of power to use for your entire RV. It still passes power BUT you really don't know how much. Using a meter or the Power/Pedestal Tester would tell you BUT a 50 amp EMS unit will not.

If you have either a 50 amp EMS unit with a 50-30 adapter or a 30 amp EMS unit and plug into a 30 amp pedestal and it passes power you now have 30 amps or 3600 watts of power to use for your entire RV.
