First, let me thank you all for the awesome discussions you've been posting thus far on this forum -- I really, really appreciate your wisdom and experience!
I am interested in installing 50 amp service using an inlet on the exterior of my bus as I'll both want to be able to connect to campgrounds when I find myself in one and because I want to be able to connect the bus to a temp power pole while building a house (e.g., run a dedicated power tools circuit from the breaker box back outside the bus to power tools while building). Yet, I often find myself in places where I'll only have access to the standard 20 amp service that comes via extension cord.
As I understand it, 50 amp service are two 110v connections as well as a neutral and a ground. Each 110v connection powers one side of the service panel. That's all well and good when I have access to 50 amp service; however, if I am plugging into 20 amp service (using two dogbone step downs on the exterior cord, e.g., 50 amp-->30 amp-->20 amp) (dogbone converters link: https://www.amazon.com/dp/B01N8UDPIJ?psc=1
) the service panel will then split that 20 amp connection (because of the two 110v cords from the 50 amp inlet) into two 10 amp connections . . . which isn't really enough power to power anything and will likely damage things.
So my question
: Is there any way to wire (using some sort of generator setup or something else) the 50 amp inlet to the service panel so that when 20 amps are plugged in they'll only power one
pole delivering 110v of conventional extension cord fed service? If so, how? If not, does anyone know of a work around for this issue?
Forgive me if the answer to this question is glaringly obvious ("Duh, dude, you can't do that" or "Yeah, dude, you need part X") . . . I'm pretty new to this.
Any help is much appreciative. I'll augment this post with answers received here as well as an equipment list to assist future posters that may have the same or a similar question. Thanks in advance for your responses! I'll be awaiting them like this:
