Progressive Industries EMS 50amp?
A question, I have the Progressive Industries EMS 50amp hardwired in my coach, works great. I have never given this any thought but today at storage plugged in to 15am 110 shore power I noticed on the display that it still shows read out for line 1 and line 2. I know when I hooked up the 50amp I do have 2 lines. But what is it reading for guess line 2 when hooked to the low amp storage land line.
Thanks

I have the same setup, and when plugged in to at home to 110 it does show line 1 and line 2 on display. Only 1 line will show amp draw, not both.

I noticed the same thing when I was connected to 30 amp service in AZ. As noted above, I noticed that only one leg (L1 or L2?) showed any amp draw.
It's probably in the owners manual, but I was too busy to check it.

I had similar indications on my previous coach (2004 Winnebago Journey). Amps sometimes, (not always) would show on both lines 1 and 2 when hooked to 15 amp or 30 amp.

Lines 1&2 show because your adaptor to ,30 / 15 amp are splitting the power between the two 50 amp legs, haven't got the remote yet so I don't have the read out. Maybe my birthday , dear?
Your coach separates the power in the breaker box and depending what 50amp leg is active that's the amp reading.

I've got the same unit on our coach. What you're seeing is normal operation.
Even on 110 volt, 15/20 amp power, you are still feeding BOTH legs in the coach. It has to...otherwise only half the circuits in the coach would be powered.

Yes, that is normal per Rich-n-Linda explanation. If you see amps on only one leg, that's merely because typically most of the coach runs off the L1 leg. What is wired to the L2 side varies from coach to coach, but it's common for the electric water heater, rear a/c, and washer/dryer to be on that side, but not much else.
