it may be fine according to code, but if it were me, i would
change those 20 amp breakers to 15s. if there's a fire,
you'd have some splaining to do. and when you tell
the insurance man that you got your advice on an
internet newsgroup, his head will not stop shaking.
sideways. not up-and-down.

When getting our new home wired in 1998, I asked the electrician to use 12G
instead of 14 GA.
They did but then used 20A breakers....and 15A outlets and switches.
I asked about that and they said there would be no problem, that it was OK
by code
