ARIZONA KB-2 DUAL RESIDENTIAL AND SMALL COMMERCIAL License (AZ) Arizona’s KB-2 credential spans both residential and small commercial electrical work, requiring competency across load calculations, conduit sizing, grounding systems, and NEC code applications specific to low-voltage and standard installations. The dual scope means installers navigate residential branch circuits alongside commercial feeder requirements, creating broader technical foundation than single-sector licenses demand.
