This differs from the purpose of Chapter 3, which is to correctly install the conductors that make up those circuits.

It’s also highly detailed about the installation and restrictions involved with wiring methods. It’s because of that detail that many people incorrectly apply the Chapter 3 wiring methods rules. Be sure to pay careful attention to the details, rather than making the mistake of glossing over something. This is especially true when it comes to applying the Tables. The type of wiring method you’ll use depends on several factors: Code requireme...
