I'm in a 30-year-old RV that is pretty much all original with its 30-amp service plugged in through the correct adapter to a dedicated junction box. Unless I open the junction box (not comfortable doing that myself as I have zero experience with AC current), there's really no way for me to access any of the feed wiring. My old man can wire up something if need be, but I need something weatherproof without breaking the bank, because the junction box and the cord feeding the RV are out in the weather.
Open the junction box, it won't bite yet.
Take a look at the joints made in there.
Should be safe to just slowly bring the black wire out a bit, enough for clamping the ammeter over the black only.
Take your reading.
That will be what you seem to be after, total load, yes?
Not sure of your intentions but if it ain't broke, don't fix it. If the 30 amp service isn't tripping and branch circuits aren't either, you are in good shape I'd say. No need for individual circuit testing but that can be done in the same way inside the panel on each ire coming off each breaker.
You have to start somewhere to get used to working on live circuits. Remove the cover on the panel and you will see it can be easily done as far as ammeter testing goes. Anything else requires more diligence with no distractions.
