My breaker panel has three breakers labeled "lights and outlets",
presumably by the builders.

Today I went to map which switches and outlets are connected to which
breaker. I stuck colored dots (blue, red, yellow) on each breaker,
and then stuck corresponding colored dots on each switch and outlet.
One circuit (yellow) has a GCFI, with outlets in the hall bath and
master bath.

What I found is that several outlets in the kitchen and dining area
are live on both the blue and yellow circuit.

Is it common to have outlets connected to two breakers? Especially
with one of the common breakers GCFI-protected?

Any thoughts appreciated.

Thanks a heap

Let's hope you mean that one socket of the duplex outlet is on a yellow
circuit and the other is on the blue circuit. This could be correct. Each
of the two outlets of the usual duplex outlet are by default on the same
circuit. However it is possible to change this so that they are each on
different circuits.

It is also possible that someone intended to wire it as indicated above,
but forgot to remove an ear or two and now both circuits are being feed by
two different breakers, hopefully on the same leg. If this is true you have
a situation that really needs to be corrected and I suggest hiring someone
who knows what they are doing as they will up up against something that is
not in most books and unless they personally know what to do someone could
get hurt or burn a house down.
