Roger1,
Remember all you are trying to due is safe guard your gear, as long as you do not have a problem doing that all is good, I do not want to needlessly keep resetting my breakers all the time if they are to light for the actual running I do, on the other hand I do not want to damage anything either. Actually the 7 Amp breakers are probably even better, and some time I just might invest in them.
