Electrical Inspections and Definitions


  • Rough-in Electrical. This is generally the first inspection made. Everything that will be covered by finishing material such as sheetrock will be inspected for compliance prior to cover up. This includes smoke alarm wiring and locations, low voltage wiring, etc. 
  • Temporary Electrical. As the name implies, this is a temporary inspection which allows MLGW to set an electrical meter in order to provide an electrical service for use during construction. The requirements for this inspection are to have the service conductors and grounding electrode conductor terminated and bonded correctly and at least one branch circuit and receptacle connected to the service panel with all other unused outlets disconnected or terminated in a safe manner. The connection to the grounding electrode must be visible for inspection approval. If the residential service conductors are not sized to carry the total amperage sum of all service MAINs, a load calculation sheet must be provided to determine the actual expected load.
  • Above Ceiling. Most commercial buildings incorporate a 'drop ceiling' design where the space above the ceiling contains electrical conductors, cables and equipment between the roof and the ceiling tiles. An above ceiling inspection allows the ceiling grid and tiles to be installed and the electrical work to be concealed. All cables that will not be terminated at the time of the ceiling inspection must be secured and at the correct location below the ceiling where nothing will be concealed that would require an additional inspection. A separate inspection is required for each permit associated with the project such as fire alarm, voice & data, alarm systems, cable systems, speaker systems, etc.,,
  • Partial Inspections. Partial inspections will be done as needed to accommodate the progress of the project. Partial inspections need to be requested in an organized manner. The request of a partial inspection needs to include as large of a section as possible for each inspection.
  • Smoke Detectors. All required smoke detectors will be tested using canned smoke. All audio/visual indicators and system shutdown must be operational for this test to pass. The Town of Collierville Fire Marshall must also approve the smoke detector test when required.
  • Approved Plans. Any changes or deviations from the stamped approved plans must be approved by the design professional engineer by means of a stamped and signed engineer’s letter.
  • Electrical Final. This is the last inspection to be made by the electrical department and includes all heating and air conditioning equipment, kitchen appliances, water heaters and all finish items such as lighting fixtures, receptacles, trim plates and covers. The final electrical inspection is required before calling in for a building final or certificate of occupancy.
