Service installation location

Q. Article 230 does not allow a "service" to be installed in a bathroom. Is it permissible to install a subpanel in a bathroom?

A. In commercial buildings, yes. In dwellings and guest rooms of hotels and motels, no. Please see Article 240.24 (E). The key word is "overcurrent devices."
