Question:
Hello Charlie. We are working on an upgrade of an existing bank in, where the janitor closet was installed inside the Electrical room. The architect is asking if this configuration is approved by the Electrical Code or if we need to move the janitor sink to a new different location/janitor closet. I look forward to your response, Erguin Capote
A
Answer:
Erguin, thank you for participating in the CQD. In general, the NEC® does not prohinit this, but there are some factors to consider before deeming the installation code compliant:
- Deteriorating Agents – Section 110.17 prohibits conductors and equipment (unless identified for use in the operating environment), to be located in damp or wet location; where exposed to gases, fumes, vapors, liquids, or other agents that have deteriorating effects. It is fairly common for cleaning chemical dispensers to be installed in or at the janitor’s closet/sink. Some of these cleaning chemicals may have deteriorating effects.
- Working Space – Section 110.26 requires working space about electrical equipment. The sink or anything the janitor may store in that closet/room cannot impede on this required space.
- Overcurrent Devices (OCPDs) – Section 240.24(C) prohibits the installation of OCPDs in locations where exposed to physical damage, this would include deteriorating effects. Section 240.24(D) prohibits the installation of OCPDs in the vicinity of easily ignitable matrials, like paper products commonly stored in janitors closets.
