Yea, what Bud said. This is the reason that 20 amp circuits are now required
for bathroom outlets.

redoing a bathroom or kitchen today and not installing dedicated 20
amp circuits is just plain dumb.

too many power hungry devices, and new ones being created constantly.

its akin to upograding your main service from 60 amps to just
100........

one day you will regret cheaping out............

the cost of bath dedicated 20 amp GFCI circuit as compared to the
overall job cost to remodel the bath to studs is a minor
expense........

plus long term operation of a breaker over its rated limit ages them,
and sooner or later the breaker will trip faster. thats what they are
designed to do.

age to more sensitive........


one last point, even if the main service were maxed out, i would still
run a new dedicated 12 gauge wire for the bath outlets, and connect it
to another 15 or 20 amp circuit in basement or utility room till the
main service is upgraded or a sub panel installed........

its not ideal but costs little and is way easier than snaking a new
line to the bath when your fashion concious wife decides blow dryer
plus curling iron is the only way to do her hair........

that combo would trip the 15 amp breaker fast.....

save money on a less expensive sink, but do the wiring properly
