In regard to NFPA 110 paragraph 7.2.2. I have a hospital facility that has an open roof equipment yard that contains the EPS as well as an air cooled chiller and chilled water pumps. The EPS is located in its own enclosure meeting the requirements of paragraph 220.127.116.11. My interpretation of paragraph 18.104.22.168 is that as long as no other equipment is housed within the EPS enclosure than the installation is acceptable. We have a state review comment that is indicating that the presence of the mechanical equipment in the yard creates a code violation.
