I re wired my home in 2008. Fortunately for me the 08 code didn't require GCFI for dedicated appliances (refrigerators, sewage pump, dishwashers etc).

The downside was I had to toss all the AFCI breakers required in 2003 when I had to R&R the main panel when the main breaker failed and replace with combo breakers. Also, I ended up with a box full of conventional 15 & 20a breakers due to needing combo breakers in so many places.

At least in the kitchen and baths I could use GCFI receptacles or dead fronts.

The new wiring has 5 panels (2 40 circuit and 3 30 circuit) so much money was spent on new breakers. Ok, the pair of 40 circuit panels are only half full as is one 30 circuit panel.

Hey, Rob has to keep the battery charged on his Harley!  How else is there?  ;)

No cams. A pair of 200a services underground for 375 ft.
Two panels are on a transfer switch for the genset.

Pretty big house. 3 circuits for lighting in kitchen (7 dimmers) and 11 outlet or appliance circuits.

I just did a 68,000 square ft warehouse with 4 lighting circuits-how much light do you need? :o

New dishwashers aren't safe without a GFCI-not sure how they get "Listed" :-\

I should qualify that-I was told that the NEC added the GFCI requirement to dishwashers becasue manufacturers said they could not make them safe without GFCIs.  That was part of a code update class and I assume that information filtered down from code committees.  My guess is there is so much plastic, they can't guarantee a pinhole leak in a heater will trip a a breaker before electrifying some component.

It seems appropriate for appliances that mix water with electricity to have GFCI. My dishwasher and washing machine plug into the same outlet. I replaced the outlet with GFCI mainly because the old outlet became intermittent after decades of use. FWIW the old outlet was ungrounded, which seems the larger sin than not being GFCI. I grounded the outlet to my fuse box only a few feet away.

I have had one GFCI ghost trip so far, a couple weeks ago. It may have occurred mid cycle while the dishwasher was operating and I just didn't notice until next time I tried to use the dishwasher. It hasn't misbehaved since.
