I'm not a professional, however I know enough to be dangerous 
Ive done the normal electrical plugs and adding breakers and circuits but never ran service to a sub panel.
Length from main to sub
30 ft
200 amp service at Main (6 slots available)
My sub is a 100 amp (maybe 125 can't remember) with 12 slots.
I'm doing the hard work my self and will let a pro hook everything up.
.
At this moment I'm using 5 slots. ( 3 for lights 2 for outlets)
I want to run 220 eventually and also might split one of my outlet runs into two breakers.
So how many wires do I run?
How many breakers do I use at my main?
What type of wire?
I've don't some research but want to hear from you guys.
