Medical facilities have many different requirements and wiring methods all of which are dependent on level of care. Critical, emergency, normal, essential, life-safety are examples of the different terms used to delineate which wiring methods are used. Hospitals require as many as three different systems providing electricity in the same area of the building. Some circuits automatically connect to alternate sources, while others do not. Operating rooms require isolation panels to eliminate shock hazards for patients in an anesthetized state. Redundant grounding is required for all patient care areas in all facilities. Special precautions must be taken in existing occupancies to avoid contaminating specific patient treatment locations. We take great care to perform our own research and coordinate with designers, inspecting authorities, other contractors and maintenance personnel to ensure our installations safeguard the people who are to be treated.
