Have plans to pickup our new toy hauler (with 50 amp capability) next week.
Couple Questions:
1. When you use a 30 amp to 50 amp pigtail converter plug, is the single 30 amp input simply placed in parallel with each/both of the TT's two 50 amp circuits?
Yes, the two "legs" on the 50 amp trailer/Motor home side are simply connected together.. So you can draw a total of 30 amps, but all curcuits inside are normally "live"
2. For those that use a 50 amp Progressive Industries EMS system with their on-board OEM 4000/5500 Onan generator, do you have any issues with the E4 ground error? I ask because I've found a bonding plug is necessary when using the 30 amp PI EMS with a portable Honda/Yamaha/Champion generator.
Thanks!
Not when using the adapter. The ground is still present and it still shows. Now the PI EMS (IF that is the one we usually call Surge Protector) Does not care if you are plugged into 30 or 50 amp, it works the same, if anything one of the functions works BETTER on 30, (but only one). That being spike supression.
The other kind of Energy Manager (load shedding) The kind that will turn off an A/C or the Water heater if you draw too much power.. IT does care if you are on 30 or 50.. It will stand down if it sees 240 volts (or close enough to it) across the legs, but if it sees the two legs connected together then it activates, Displays total amprage, and sheds as needed to keep you below 30.. one hopes.
This is very useful for those who have Mrs. Douglas Syndrom (TV SHOW Green Acers, Played by Eva Gabor) She was forever plugging in too many appliances and blowing the Generator.
