| If the AGFI is tripping, then you have a wiring problem. Somewhere
electricity is leaking in paths it should not - a problem most apparent
during higher humidity or rain.
AGFIs do not breakdown with humidity nor do they get weak.
Generally, AGFIs are only installed on bedroom circuits as required
by code and essential to human safety.
Smoke detectors are suppose to be on their own dedicated circuit AND
not on AGFI circuits. Obviously if a bedroom extension cord does cause
a fire and trips the bedroom circuit breaker, then do you want the
smoke detectors to stop working? Again, all bedroom circuits must be
AGFI, and the smoke detector should be on a separate circuit. For
multiple reasons from what you have posted, I would be concerned about
the quality of that electrical installation - especially after that
comment about humidity breaks them down. Humidity creates a problem
when the wiring has a defect somewhere.

| Is this documented in the NEC? If it is, can you cite the section for
reference?

| The electrician called yesterday and zeroed in on the ceiling fan I
put in! I didn't loose that bet.
I'm not sure what their thinking is on this. Does the thunder vibrate
wires to short out or does Hunter fans reason a storm is here so lets
pick on the humans?
I'm a little 'smoked' about smoke detectors that have to be reset
after a power outage, and ones that do not have an indicator they are
not working.
Humidity - this is south Texas so most of the time the house is shut
up with the air conditioner on. But then the last electrician did say
the AFIs were effected especially since Tilson puts the breaker box
outside.
Like so much crap with this house the electrician asked why I did not
request they put the box inside the garage for about $50 more!

Replacing a smoke detector is almost as easy as a light bulb. There should
be a 3 pin connector when you pull it off the cieling. LAst time I looked,
HD had at least 5 models of wired detectors some with and without battery
backup and most well under $20. Just go out and buy new detectors with
features you like and are appropriate to your house. You're supposed to
change them out every 10 years anyway especially CO detectors.
Cieling fans tend to collect a lot of dust inside. perhaps the humidity and
the dust are creating a leakage path enough to trip the breaker.
