plans are for those new outlets. if they are just going to give you additional outlet in others of the garage for convenience to periodically plug in a drill or circular saw. then just added additional outlet with the same wire size is used for the original run from the breaker will do just fine. If you are not at all handy with electrical wiring work...hire it our to a good experienced handy man or licensed electrician to handle. better safe than sorry...dont want you to get shocked or end up causing a house fire if you used undersized wire for the circuit breaker protection you have! You may even need to have a new higher current capacity circuit added from the breaker box with a new 20 amp breaker added to boot. good luck LJ
