| Subject: | Re: Non-aero GFCI question |
A point of nomenclature.=C2- The phrase "in series" has been used inaccu
rately in some posts in this thread.
A GFI should never be "in series" in an outlet circuit, that would be a gro
ss wiring error.=C2- The proper term is daisy-chained.=C2- This is wher
e additional outlets are installed down-stream of a GFI and the GFI provide
s ground fault protection to those outlets.=C2-=C2-
As I'm sure most people on this thread understand, the down-stream outlets
must be connected to the proper terminals on the GFI and the are in paralle
l, not series.
This practice is quite common as a cost-saving maneuver by contractors.=C2
- They install 1 GFI to protect a bunch of down-stream outlets instead of
installing an individual GFI at each location.=C2- Thus saving a few buc
ks.
War Stories:#1
I have helped many friends and family, over the years, when they call and s
ay "the outlets in some room, usually a bathroom, or an outside outlet, don
't work - but they were working yesterday".=C2- But the outlet in questio
n is not a GFI.=C2-=C2-
I tell them to go find the single GFI, (which can turn into a scavenger hun
t).=C2- Look in the garage, basement, or back bathroom and press the rese
t button.=C2- I always get a call back a few minutes later "you're a geni
us!".
#2
When I moved into my house about 6 years ago, I had a GFI (installed in the
downstairs bathroom) that would mysteriously and seemingly randomly trip e
very couple of weeks. Weird.Long story short (pun intended;)... My wife had
placed some twinkle lights in the garden.=C2- The sprinklers would run a
couple of times a week at 0400.=C2- If the twinkle lights had been left
on all night, the GFI would be tripped.=C2- If not, the lights would dry
out over the next day and everything worked fine.=C2- Took a while to fig
ure that one out :)

Glen and Skywagonguy and all,
Same here, no GFCIs in series.=C2- The subpanel is powered by a standard
breaker right off the main panel.=C2- The common and two power leads are
wired to the right buses.=C2- There is a dedicated ground wire tying the
main panel=C2-and subpanel together.=C2- It's a little odd though that
the ground=C2-wire is several sizes smaller than the other three.=C2- I
don't think that would cause a problem, but I wonder how much current it w
ould carry over its 250' run.
Today I moved the GFCI breaker to a circuit that just has a single outlet a
nd a light, immediately=C2-adjacent to the subpanel.=C2- I replaced the
GFCI breaker on the=C2-outdoor plugs with a standard breaker, and I will
put a GFCI breaker at the plug I use the most.=C2- Fingers crossed, I ho
pe to learn another thing or two.
Thanks everyone for great suggestions.

GFCI breakers and outlets are very sensitive.=C2- And some are more sensi

than others.=C2- And some are too sensitive.=C2- =C2-All it takes is
a few milliamps
difference between the hot and neutral to trip.=C2- 50 milliamps through
a
person's heart can stop it from beating.=C2- I suggest that you replace t
he GFCI
breaker with a standard breaker.=C2- Then replace every outlet with a GFC
I
outlet with no other outlets downstream of each GFCI outlet.=C2- Now if a
GFCI
outlet trips, either the load is defective or else the GFCI outlet is defec
tive.=C2- If
a GFCI outlet trips off, then power is only lost to whatever is plugged int
o that
one outlet.=C2- The other GFCI outs should not be affected.
