Understanding 50A in my RV
I understand there are two legs, each carrying 50 Amps to the RV but I'm having trouble understanding what gets serviced by L1 and what gets serviced by L2 of the 50A service and why are there two leg...
Forum Discussion
I would like to expand this topic a bit and look at the RV pedestal for 50amp service. The park I’m at has L1 and L2 at 120v, but only 208v across L1/L2. My Southwire ATS is looking for 240v across L1/L2. My clothes dryer and cheap heat also draw 240v. Regardless, my ATS will only allow one leg of power to the rig from the pedestal; basically a 30amp power supply from a 50amp supply. Is the pedestal not wired properly at the park?
Sounds like the pedestal is wired to 2 legs of a 3-phase feed, not horribly unusual in a large installation. Last I heard it was pretty unusual for an RV to have any 240 volt devices. You should be able to draw 50 amps on the one leg.
Is it very hot and the park very crowded? If so, the combined load can drop the voltage to 208. 104V on each leg may damage some components in your RV.
