Reddit reviews Wiring Simplified: Based on the 2017 National Electrical Code®

Everyone mentions local codes, but few actually read them. Even fewer are qualified to interpret them. Instead, they're repeating what they've been told by teachers, tradesmen, contractors, and (especially) inspectors, and what they've learned from reading other books and product manuals. It's also a catch-all for possible bad advice: "Check local codes" on /r/DIY is the equivalent of saying "I am not a lawyer" or "check with your doctor".

If you have a strong opinion on something and have been told "it's required by/against code" and want to go look it up, have at it and good luck.

If you want to do a project and make sure it complies with local code, I suggest getting reference materials instead of the original code. Buy a copy of, for example, Wiring Simplified to learn how to do wiring that's compliant with code (that's one I've personally used, it was pretty good). Let an expert read the legalese and translate it into how you ought to implement it.

Everyone else has said everything I could say and more so I'll recommend these two things:

• Buy a copy of Wiring Simplified. A section of the book goes into great detail about conduit and is well worth the (IMO, inexpensive) price of the book alone. Even if you don't touch a single wire in your home yourself the reference is invaluable as it will help you have informed conversations with your contractor.
  
  
• Make sure there is some form of conduit running from the termination point (usually the utility room) to the attic space. Codes will probably require this conduit to be sealed or fireproofed in some way but make sure this is a large diameter conduit. It will be incredibly difficult to predict all future scenarios where wire and data cabling will be needed. Having a conduit running to the attic will allow you to fish cabling to the attic and down through the interior walls into the rooms below.

A link to another Reddit thread is not exactly authoritative. This smells like the kind of FUD electricians sometimes use to drum up extra business from unsuspecting homeowners. Link directly to a manufacturers data sheet or some other very authoritative source and I might believe it, but I have learned a long time ago that a lot of electricians are either dishonest or incompetent (I have seen "licensed electricians" do some really boneheaded things, like not hooking up the ground wires inside a secondary breaker box. In that particular case, his excuse was he meant to do it, but forgot!).

So if your source is some electrician's site or some electrician's trade group, I will give those sources about zero credibility, half the time all they want to do is sell homeowners stuff they don't need. Not that a breaker can't go bad after two or three uses, in fact they can be bad when brand new, but that is certainly not a normal thing. Electrical inspectors sometimes test breakers using a device that momentarily shorts the line, are they reducing the breaker life by a third when doing that? I don't think so.

P.S. Every homeowner in the USA would do themselves a big favor if they got the book "Wiring Simplified: Based on the 2017 National Electrical Code®" - it's been around for over 80 years but is updated with each revision of the NEC. I bought a copy of a much earllier version at W.T. Grant's when I was about 10 years old and read the whole thing cover to cover, and was fascinated by it (yeah, I was a strange kid). It explains electrical wiring in a way that any handy person can understand. Even if you don't feel confident enough to do some of your own wiring (or your local codes don't allow it), at least you will have some idea of what an electrician is doing and whether they have done the job right.
