But what I dont understand is how the 25 extra amps at the sub makes any difference.
For example. My 100 amp sub has Eight spaces, Seven of which are used right now. One curcuit is used for Two small water pumps. The other Two 120v curcuits are for outlets, half the outlets to One the other half to the other curcuit. Then there are the Two 220 curcuits.
If I am correct the feed wire is rated to 125 amps (#2 copper) so I guess I could upgrade if needed but I figured I would rather have my breakers be the week link versus the wire?
Man if I let the stuff get away from me it can get real confusing.
