Question on voltage monitors

Thank you for all the replies. It makes sense to me and that confirms what I was thinking. I think the fact that they had it hooked to 30 amp at the dealer using the 50 to 30 adapter which they gave me is probably why they sold me a 30. since I have a 50 amp hookup on the 5th wheel I figured I would hook 50 on all chances I can and having a 50 amp surge protector makes sense

Presumably you understand the 50 amp version of Progressive EMS is going to cost you more than the 30 amp initially sold to you, 'though you might attempt to convince the dealer that because they sold you the incorrect unit they should cover that additional cost. Out of curiosity, just which Progressive unit did they sell you? :@

Secondly, you presumably also realize there's a HUGE difference (i.e. 70 amps) between 30 amp RV service (i.e. 3600 watts) and 50 amp RV service (i.e. 12,000 watts) since the former is 30 amps across just one leg whereas the latter is 50 amps across each of two legs. That's a BIG difference and to take full advantage of the fact your rig is wired for 50 amp service you want to be plugging your 50 amp rig into a 50 amp campsite source using a 50 amp Progressive EMS whenever that power source is available. At other times when only 30 amp service is available simply plug into that source using a 50 amp female > 30 amp male dogbone, keeping in mind that your total draw will be restricted to just 30 amps.
