I don't think anyone has said the switching of hot and neutral was not a safe way to go. Are there some likely very rare circumstances that having ground also switched might save someone, probably,...

I kind of agree with the final statement. In general yes, but not always with RVs in a couple of cases. Unless you drive a ground rod they can't be earth grounded when off shore power, so all the...

In actuality, you would probably only need the jumpers if you were doing the power shedding with two separate 110v boxes with a 110v input, and you would just use one wire of two hots for the inputs...

For curiosity, I just did a quick search for 3 input automatic transfer switches.


I actually found one this time, albeit a 50 amp and quite expensive one.

I had thought you had mentioned the first being a hot only, but I see it was in regards to priority not what wires were switched.

As Marko said, that should mean it is bonded somewhere, but it won't say where. If you are not plugged into shore power the bond would have to be in the van, but if you are plugged in to shore power...

I have messed a bit with checking with a meter and it is pretty difficult as how much voltage you get on each line if they are bonded can vary a lot based on their actual resistance to ground or to...

Yes, if you have an ABT that uses common grounds and common neutrals you have the potential for a second bond and the hazard that goes with it. I think those setups are why the major generator and...

As I mentioned, the 1500 watts would be 150 amps at 12.0v and about 80% efficiency AT THE INVERTER, and that would not cover the double output of a 3000 watt surge so figure 3000 watt surge will pull...

It just occurred to me that your inverter said it had a 3000 watt surge capacity. That is going to take 250 amps a 12v and 100% efficiency and over 300 amps at 80% efficiency. Add to that the fact...

Generally, on things with starting surge as much as 100% over rated might be needed in a fast blow breaker or fuse. Slow blow and you can go much closer. I would go at least 200 amps for a test.

How big is the breaker? We used to run the Dometic microwave in our 190 off a 1500 watt PSW Samlex inverter without issue. I think I had a 250 or 300 amp fuse in the line to it. I think I would get...

Sounds good to me, should work well.


I didn't go back over it all again to see, but do you have a shunt and monitor in the system? Now that you have the PD charger, and I think it comes with...

I think the Tripplite would have been a 45 amp of charging unit so upwards of 650 watts plus inefficiencies probably would use about 7-8 amps of 110v AC. That and the Keurig would almost certainly...

Yes, that is a better way and it would be the essentially the same as the sketch in post 16. You should be able to split of the AC to the Tripplite in the box it pluge into for it's power.

That is a good explanation of the need of bonding and more detailed than the standard "you need a bond or your ground wire is of no use" because of no return path so it would run high also.

If the unit is internally and permanently bonded will really only determine if you would need to bond it yourself or not, I think, for a wired in system like this would be. I don't think it would...
