I have attached some info I found on a search. I have attached the
links also, this may help. But from what I have read, it sounds like
this breaker is sensing an arc when your fridge kicks in. Still the
question is how it senses on a seperate line. Again from the reading,
these asti breakers are extremly sensitive, and may be sensing that
feedback I stated earlier. Please read below........... I still say
that your fridge is the culprit. Also check the below white wire
attachment.....wonder if this coiled wire is attached properly?
Hope this helps.
The White Wire
AFCI breakers require one additional step. You need to locate the white
wire that is paired with the black wire in that circuit. The white wire
actually attaches to the breaker as well. There is a coiled white wire
that leads out of the breaker. This white wire attaches to the neutral
bus bar in spot that is vacated when you disconnect the white wire of
the circuit. Scared yet? If so, call an electrician!
Summary: Electrical fires happen every day in the United States because
of electrical shorts that produce intensely hot arcs. An arc fault
circuit interrupter senses these arcs and stops them, making them
smarter than traditional circuit breakers.
These devices work and act like a traditional circuit breaker except
that they are smarter. Many of these new devices contain small filters
and logic devices that allow them to sense an arc just as it is about
to produce the sparks and intense heat. If arcing conditions are
present, then the breaker trips instantaneously.
Do not confuse these devices with the personal protection ground fault
circuit interrupters (GFCI) that have been around for over 30 years.
The GFCI circuit breakers, at the present time, do not have the
capability to sense arcs.
The new arc fault circuit breakers are identified in section 210-12 of
the 1999 edition of the National Electric Code. Beginning January 1,
2002 they will be required to protect branch circuits that serve
