A few years ago while remodeling I installed a CFI (sp?) outlet for the
microwave oven.It seemed like a good idea at the time. However, last night a
lightning stroke took out all of the power in the area
for a while. When it was back on, the microwave
oven was dead as well as the toaster also plugged
I checked the outlet and it had apparently tripped. I tried to reset it, but
nothing happened. Can someone tell me how to get thee power back on in that
GFCI's offer no benefit as a power conditioner/lightning arrestor, they are
just fancy circuit breakers filled with electronics that usually fry
themselves with any voltage surges.
While you can change it for another gfi outlet, I would just pop in a
(and might even be tempted to run a second line and split the outlet)
As a microwave AND a toaster on the same outlet is not very likely going to
allow you to use both at once anyway.
BTW, while this may seem obvious, you did test the microwave and toaster in
a different outlet didn't you ?
GFCI's are NOT related to circuit breakers, other than both devices cut of
the power in different situations. This is a myth that people don't seem to
understand is not true.
- Circuit Breakers cut off power in the case of an overload condition (too
much current through the breaker.
- GFCI's cut off power in the case of a ground fault -- that is, the power
going out the hot slot does not balance with the power coming into the
neutral side -- which potentially means current is flowing through someone's
body to ground, e.g. someone is being electricuted.
GFCI's will NOT protect against overcurrent. That's why you need both
devices. GFCI breakers have both functions combined into one package.
While you are somewhat correct, pulling a few words out of context means
As many GFI outlets also have overcurrent protection built in.
I do agree that a GFI should also be used in conjunction with a proper
But I never stated it shouldn't be.
The OP was concerned about damage after a lighting strike.
The need for a GFI is probably unwarranted for a microwave, and can be
replaced with a regular outlet.
And if the GFI is tripping it could also be caused by damage to the
microwave plugged into it.
If you read my complete post, you might have seen that.
So we can see there are definitely different rules in different areas.
Here in a kitchen all (new)counter outlets MUST be split with two branch
circuits, and only 2 outlets total on any (kitchen) circuit.
So GFI outlets are not even possible.
GFI's are only required within 3 feet of a sink/tub/shower, or outdoor
And ALL GFI outlets MUST be grounded.
And remember that "new construction" and "repairs" are governed by different
Personally I still think GFI's are over-rated by many, and are not only
unnecessary in many places, but simply don't work.
Appliances with motors often fry them.
e.g. Refrigerators, Washers, Freezers, Sump Pumps, etc.
I've never heard of a GFCI being "fried" by a motor. The reason that
certain large appliances (refrigerators, freezers, sump pumps) are allowed
not to be on a GFCI is that the startup surge current of the motors
sometimes causes them to false-trip. They don't FRY though, you simply have
to reset them. But by the time you notice, the food has spoiled or the
basement has flooded.
Yes, it is the motor starting currents that do the damage.
That's why most appliance makers state they do not recommend GFI's being
used right in the instruction manuals.
Often the electronics do fry, but without any outward signs.
Even "dirty" power (surges/brownouts) to a house can eventually do them in.
e.g. it doesn't trip anymore,.....ever,..... even when it should.
I would lay odds if you checked a bunch of GFI's that were "in use"
randomly, probably over half would not be offering ANY protection, or be so
far out of spec to be effectively useless..
How many have you ever seen properly "tested" after they were in use for a
while though ?
Those test buttons on most only cause a dead short, not a real ground fault
That's why I laugh at the people here who say, GFI's don't even need a
Once there is no protection, you might as well just have a .89 cent outlet.
BS! The test button puts a resistor across the hot (load side) to the neutral
(line side) to imbalance the current (by 10mA or so) in the load side hot and
neutral wires. This acts *exactly* like a fault to ground and the GFCI trips
exactly in the same way it would from any other ground fault. If the test
button shorted the output there would be much smoke.
They don't! All circuits *should* have a ground (though some legacy circuits
don't) but a GFCI does _not_ need a ground to function properly. An ungrounded
circuit protected by a GFCI is far safer then an ungrounded circuit not so
While this is true of any safety device, a functioning GFCI may save your life!
Are you against smoke alarms because some don't test them every month? After
all, a smoke alarm with a dead battery might just as well be an ugly wart on
Sorry to come off rude, but you obviously don't know what you're talking
about, and I ask that you please not answer questions related to GFCI
outlets or any other area that you don't have knowledge in. Your advice is
incorrect, and could be downright dangerous.
If you disagree with my assessment, could you please provide cites for the
following 'facts' that you have claimed to be true:
- GFCI's are not required in kitchens
- GFCI's can be damaged by motors in common appliances such as
- GFCI's test buttons short out the circuit (which is prehaps the most
idiotic thing you've said yet).
- GFCI's can trip due to overcurrent situations.
I don't suspect you'll reply with said cites, but instead try to slander me
and then say "Plonk". Mind proving me wrong?
AMUN Can provide nothing. He never has and never will. Warned AHR many
times about his crappy and you said it, dangerous advice.
Thank you for responding to this yutz.
Do NOT under any circumstances take advice from an idiot named AMUN.
Regarding tile, electrical, HVAC, painting, drywall, plastering, lawn
mower repair and various other construction issues, AMUN is a clueless
moron. As things go AMUN will dissapear as his kind usually does when
confronted with their bad advice by those who are knowledgeable in their
respective fields. Until then - BEWARE
