I am sure you know this but it wasn't noted in the article. My Motorhome (2012 Monaco Knight) has a Power Control System (PCS) that automatically senses whether it is connected to 30 Amp 120 Volt AC shore power or 50 Amp 240 Volt AC shore power or the generator. When it sees a less than 30 amp shore power connection it activates the Shedding function. A few years ago I was in a KOA and when plugged into the 50 amp receptacle my PCS reported 30 amp. I checked the pedestal with my meter and found that there was 0 volts between the hot legs. I complained to the manager and just got a blank stare from them. I was allowed to move to another site that was wired properly. So the Y adapter could cause this condition.
Actually there’s a 50/50 chance that the two 30-amp pedestals are wired on L1 and L2. In that case 30 amps on pedestal 1 and 30 amps on pedestal 2 would null out to 0 amps on the neutral conductor after the Y connection.
All fine and good as long as the feeder wiring and breaker to the pedestal is rated to handle the current. Electrical design rule of thumb, do not load wiring, breaker, fill a conduit and etc more than 80%.
Really interesting article Mike! So, you are telling us that the manufacturers say that it is ok to run 60 A through the neutral leg of a 50 A system which is rated to draw 50A per split phase leg. I wonder what size wire they are using as my understanding is that the neutral current should be 50A maximum when running split phase? 6 AWG THHN is rated for 75A at 90 C unbundled but it would be interesting to hear if you know the wire size and temperature rating they are actually using in an RV dog bone or extension, or the RV itself.
Any recommended electrical protection gloves for work around rv or home? Confused with all online search. I have 30 amp class A. Installing Softstart for ac. Turning all breakers off. Healthy safety concern around electric. Maybe short article? TIA
