This infographic explains the key differences between Mechanical Services Switchboards (MSSB) and Distribution Switchboards in Australian commercial and industrial buildings. It highlights how MSSBs power and control critical mechanical systems such as HVAC, pumps, and ventilation equipment, while distribution switchboards safely deliver electricity to lighting, outlets, and general building operations. The visual outlines safety protection, load management, fault isolation, and energy efficiency benefits, helping property owners and facility managers understand the importance of compliant and well-designed switchboard systems.
