I am on the other side of this electrically
Since you have a fresh canvas do 50 amp from the get go
it barely costs extra maybe $100
I can use 120V 15/20/30/50 and also 240V w/50 so more options better
you need an electrical box to hold breakers (same)
breakers (same limit to 15 amps)
wire (same limit to 15 amps) 12ga wire is safe to 20 amps
so once you have the box mounted and 15 amp circuits run you are golden
what is difference in 30 and 50 amp service?
30 amp you have 2 light bulbs a fridge and small ac on
50 amp you have outside lights on, disco ball going, fridge, blender, microwave ,rotisserie, 2 fans and 2 heaters or AC on...plus hot water...all on at same time!!!
Party Time!!!!, Excellent!!
Seriously for the extra $5 at site (that's what we see) it's worth it to be able to do what ever you want
And seriously except for having to get 50 amp cord 25 ft at $90 VS 25 ft 30amp cord at $35 difference of $55
and
an adapter 50 amp to 30 amp $20
and
a 30 amp to 15 amp adapter $15
now we have and extra $55 + $20 + $15 = $90 more you have every option out there for pole power
stuff inside bus is the same, same number of outlets (you can add more now
), same size and amount of wiring (you will use more with extra outlets now
) and the extra breakers...because you can
see how my thinking works?
Damn that's long
