Outback VFX with GFCI, AFCI, & 3 way switches [RE-wrenches]

[Darryl Thayer]

Hi Kelly
do not use any multiwire circuits.

The GFCI should not cause a problem in search mode. 
The GFCI measures a current difference between the hot
and neutral conductor.  If properly installed no
problem when the VFX is in search mode.  I have
several systems with VFX and GFCIs. ( be sure to get
the GFCI without a pilot light).   

The AFCI also should not cause a problem in search
mode.  The AFCI looks for short duration high current
pulses.  The pulse for search is not high current. The
only time a current would flow on search pulse is if
there is a load and the load needs to be served.  As I
understand the AFCI needs a 70 amp surge pulse to
trip.  However I do not have a AFCI on a VFX ,  If I
get a chance I will try this experiment. (also I have
been an electrician for 45 years and I have never seen
and AF on 120 volts.  I have seen it on 277 volts and
above.  

The three way problem I have never seen.  sounds like
another problem lurks here.  

Ghost loads are a real problem, such as in
electronics, and I have had problems with 
refrigerators, and things which need to know what time
it is.  So the homeowner success depends upon
selection of home appliances, electronics, and other
equipment.
