Generally, the Art. 210 requirements for branch circuits are prerequisites for applying requirements found elsewhere. This fact is exemplified by the overcurrent protection requirements [Sec. 210.20].

Article 210 contains the requirements for conductor sizing, conductor identification, overcurrent protection, and GFCI and AFCI protection of branch circuits. It also contains requirements for ...

I continue to be surprised by how many equipment designers are confused by UL circuit protection standards. In trying to meet conflicting standards, engineers may actually decrease the level of ...
