A simple issue plagues many electrical plans that can be easily remedied and potentially prevent a plan review rejection.  Circuit directories, required on the electrical plans and in the field on switchboards and panelboards, are often incomplete, vague and lack specific detail.  Article 408.4(A) of the 2017 National Electrical Code requires circuits to be legibly identified on a circuit directory located inside or on the face of the panel door for their intended purpose or use.  Sufficient detail must be provided to allow each circuit to be distinguished from others.  For instance, as seen in Figure 1 below, odd numbered circuits five through 25 are only identified as “PC RECEPTICLES.”  Missing are room numbers or other location identifiers.  See Figure 2 for an example of a directory with sufficient description on location.
