Building a new addition and have heard new codes require GFI protected outlets in kitchen above counter top also near sink and unfinished basement? Does that mean that all of the now many outlets required in kitchen all be GFI or just one on that line? Are under cabinet strip outlets no longer code? The same for basement? National codes have been updated since my last whole house wiring project.

The first outlet in line from the panel needs to be GFCI. Others connected to it, but downstream on the same circuit do not.

Dedicated circuit for refrigerator and another for freezer.may not be required but certainly a good idea. GFCI a good idea but I can't remember requirements

Do not connect your refrigerator or freezer to a GFI circuit. Ask me how I know.

I agree. I am a master electrician and do residential wiring. However it is code. AFCI & GFCI dual function. I use the dual function breakers in the panel.

The guy that wired up my folks garage had a gfi outlet in a series with regular outlets and it took me a while to figure out why there outlet had quit! The gfi was on the other side of the garage and never crossed my mind that that could be the problem!

Chas, I bet I can guess. Having as few "fail" points in running them I would think is best option. With just two now we only need a smaller low demand frig/freezer(it been actually hard to find a nice one small enough). All my trapping freezers are in my shop/garage and have running lights on them also back up gen.

Use a dual function gfci/afci breaker. They're not cheap, but it's better than being dead or your house burning down. Gfci keeps you from getting electrocuted, afci keeps your house from burning down. Also,code requires not 1 but 2 20 amp small appliance circuits in the kitchen. Personally if your kitchen isn't huge, I wouldn't worry about that so much.

Above the countertop, the two required 20A dedicated appliance circuits must be GFCI protected but each outlet on the circuit doesn't need to be a GFCI outlet. Either install a GFCI breaker to protect the whole branch circuit or the first outlet in the circuit is a GFCI outlet and that protects all of the other outlets on the same branch circuit.

Would this apply for unfinished basement as well? Code says only need one outlet needed. Know how to wire laundry and utility room. Want a series 5-6 outlets in shop area for low amp power tools. Just want to be able to run much of the kitchen outlet under cabinets where possible as all wiring will be surface and don't want it mounted on back splash walls if possible for appearance.

Hit the GFCI out let first with your home run coming from the breaker. Then tie in what ever is conveint on that wall/room. Steer clear of the breakers UNLESS you are forced to. If your doing the work on an existing dwelling you don't have to use the breakers.
THE AFCI breakers can be a pain. SOME older hand held appliances will trip them. MILLIONS of houses are working today with out them. They are a drummed up racked money maker. They came out about the same time they wanted people to tie their ground into the rebar on the foundations or footers. You ever seen a foundation that was grounded and lightning hit the house? Looks like it was dynamited....

What does the "af" stand for?
Is that the breaker now code as result of people running extension cords under rugs and stuff, causing fires?

"AF" stands for arc fault ...
The adoption of the new 2017 code .. added about $2000.00 to the price of wiring a new house today ..
Arc fault circuits, basically thru out entire house ..

This it detects any arc on the line. Hence the older style mixers that you could look into and see sparks flying off the brushes in the motor. That's an arc and it will trip those style breakers. PAIN in the behind.....

Imagine my surprise that a new governing code dramatically increases housing costs.
Then the same governing people complain about the lack of low cost housing.
Thanks for the explanation.

It's about $800 -$1000 more on a new house. About what the average insurance premium is for a year on a home to replace your stuff if it burns down. The breakers will keep you from losing that stuff on a 1 time payment. If installed properly they work well. I do this for a living and have had almost 0 call backs because of the breakers. Sometimes certain things will have issues. One homeowner had to replace a vacuum cleaner that was about 15 years old because it would trip the breakers but there was an issue with the vacuum cleaner the breaker was doing its job. If you are adding new circuits in an existing house that are over 6' long you are supposed to use arc fault breakers.
