Hi Bobbo,
I use an adapter, 30 amp to 15, plug in a kill-a-watt meter, then plug in the polarity checker. Then I add a 1550 watt heater. If there is voltage drop I know about it, and I'll use the autoformer to correct the issue.
If there is 50 amp, I use a "break out box" and test each leg individually in the same manner as above. The box has one leg with a 30 amp breaker feeding a 30 outlet, and the other leg with twin 20 amp breakers feeding two 20 amp outlets. I know it is not balanced...but I don't run over 80% of capacity. (24 amps on a 30, 16 on a 20, and 12 on a 15.) I set the Magnum remote to get to those numbers, and often use the load support feature.
So far the only fault I've encountered is low voltage. In one 15 amp location, it was 100 when I started testing and after I added the heater it dropped to 94. My autoformer brought that up to 107 under load
The surge protection is something that Mex was kind enough to build for me.
I have the kill-a-watt plugged in and I monitor the voltage while using any heavy draw items.

I always check polarity and voltage under load before I plug in my 30 amp RV.
How do you put a load on the circuit and test it before plugging in your RV?
