Small Sub Panel

I want to put a small 4 circuit subpanel in my camper. It's fed with a 20 amp service. My question is, if i have the second, third and fourth breakers for different things, can I use the first one as a main by putting the supply voltage on the load side of the breaker? An naturall when I flip the breaker on it will feed the other ones. If it will work like that, will it still trip if there is an overload?
Thanks for your help.

It gets kind of complicated to feed a panel with a 120V entrance. It can be done as you suggest and the breaker will work as long as it is not a gfci. You will need to put a jumper wire from main lug to main lug to provide voltage to the other buss. Normally a panel is designed to have 240 supplying it and by backfeeding a breaker you will only supply every other breaker. If your panel had enough spaces you could just install every other one.
