As part of a large-scale multi-disciplined project, H2M designed a 17,000-square-foot expansion and renovations to an existing 45,000-square-foot residential treatment facility. As part of the project, H2M performed a system analysis study in accordance with NFPA 70E, OSHA, and all local regulations. Studies included short circuit analysis, equipment evaluation, protective device coordination, and arc flash analysis. The modeled system contained approximately 55 analysis buses (100 electrical equipment) with normal power and provisions for a future generator.
