Is a device box for a duplex receptacle installed 1/4 inch behind a wood panel wall in an office area a violation of Section 314.20?

In accordance with Section 314.20 of the National Electrical Code (NEC), outlet boxes, including those for duplex receptacles, must be installed so that they are flush with the finished surface of the wall. The requirement ensures safety, accessibility, and proper function of the receptacle, as devices that are not mounted flush can create risks, including damage to the device or issues with the insertion of plugs.

When a device box is installed 1/4 inch behind the wall surface, it does not meet the flush-mounting requirement. Consequently, it creates a situation where the receptacle is recessed, potentially leading to improper engagement of the plugs and increasing the likelihood of electrical issues or a code violation. Therefore, the installation of a device box in this manner constitutes a violation of Section 314.20.
