MCCs are most widely used in the utilities, manufacturing, industrial, and large commercial industries that operate machinery and motors. MCCs offer enormous flexibility across differing industries and are suitable for many applications, such as: utilities, communications, oil, gas, chemical, pulp, paper, water, waste, mining, metals, industrial production, and mass-production manufacturing. MCCs are used to house various power distribution equipment and controls such as: main distribution panels (MDPs), main circuit breakers (MCBs), protective relaying, transformers, load centers, panelboards, etc.
The permit and inspection process is essential to ensure that codes, regulations, and safety are enforced to help prevent faulty or poor installations that could jeopardize human life. In most cases, engineering blueprint drawings are required to be submitted along with the permit request which must be sealed by a registered professional engineer (PE). Other permits with sealed drawing plans are required for each discipline, such as, architectural, civil, electrical, fire protection, mechanical, plumbing, structural, etc.
Arc Flash Analysis is extremely important in power systems and electric facilities (including any other facility that is comprised of major electrical components) especially for upholding the safety and well-being, including protecting electrical workers from electrical arc bursts and hazardous conditions. OSHA, NFPA, NEC, and others require arc flash studies to be performed with arc flash warning labels to be placed on the exterior of electrical equipment, cabinets, and panels indicating the proper PPE required for ensuring the safety of employees, contractors, and vendors. There are several software packages available that can aid the power professional in performing an arc flash analysis.
