One problem many people may be familiar with but not know why it is happening is called GFCI receptacle phantom tripping.
GFCI receptacles are placed near water sources to interrupt a ground fault. Ground fault is a fancy way of saying "shock!" If that could be interrupted, it would be a good thing.
You have seen them. In kitchens and bathrooms they are most visible. But they are required pretty much near any water source these days. They are a true safety innovation. And important!
This is new construction. Terrific house. Big, all the bells and whistles.
And a kitchen larger than the house I grew up in!
One thing this kitchen features is Viking appliances. They are big, well built and truly gourmet. This is one side of the Viking six-burner range.
Notice the corner.
That is a GFCI receptacle. I don't like its location.
What's wrong with its location?
This is a large family moving in. Even if it wasn't I would still have this same problem.
What do large families do? They cook. This family happens to make lots of pasta. That means they will boil a lot!
As of January 2003, UL-approved GFCIs must be manufactured to meet higher standards for withstanding electrical surges, moisture, radio frequency currents (like lightning) and other enhancements. They turn off if they detect an imbalance between the current flowing in the live conductor and that flowing in the neutral conductor. This imbalance need be no greater than .006 amps (.005 + or - .001) to turn off the power.
Here's the problem. I can find no GFCI recommendation that says it should not be installed so near to a cooking location. However, I AM EMPLOYING COMMON SENSE by thinking this one is too close. Any moisture, even excessive humidity or vapor that accumulates over time, can cause GFCIs to trip. That is called "phantom tripping." I also expect that nearly daily vapor can damage the device.
In this case, the supervisor has said that they don't like it when a home inspector offers their opinion for something, without real substance. That is fair and I agree. But this is not merely opinion - there is some thoughtful substance attached too!
My recommendation: look at GFCI locations and see if they don't lend themselves to a phantom-tripping problem. They might!
CAUTION: GFCIs often fail (perhaps as much as 20% at any given time). They should be tested at least quarterly. Most manufacturers recommend testing each month, but who is that diligent? To test, push the "test" button and verify that the power has been turned off at the device, and any downstream receptacles. And THEN verify that when the power is turned back on with the other button, it actually returns!
