  • It is always a best practice to ensure that all electrical systems are properly maintained and installed professionally to minimize chances of electrical hazards. Commercial electrical inspection ensures to eliminate potential threats and aids in determining critical defects that might cause problems.

Commercial inspection checklist and services:

The checklists are planned to help inspectors keep track of the various aspects of an electrical installation that must be examined for NEC compliance. The checklist also serves as an organizational tool for contractors and project managers to carry out self-inspections. Inspections are usually carried out in two phases; A series of rough or general inspection and final inspection. A building must pass both the phases before it can be occupied.

General safety Inspections is the basic hazard analysis and includes inspection questions like – Does the inspection task involve exposed energized conductors or circuit parts? Can the risk of this exposure be justified? Where are the boundaries for shock protection? Etc.

The General requirement of Electrical inspection include:

  1. Identifying installations or parts of installations that are covered by the NEC. 90.2(A) and (B)
  2. Verify that all installations are according to the instructions provided in the listing and labelling of materials and equipment. NEC 90.7, 110.3(B)
  3. Verify that interrupting and SC current ratings are satisfactory for the conditions of the installation. NEC 110.9, 110.10, 110.24.
  4. Verify that all unused openings are closed well. NEC 110.12(A), 408.7

  6. Check for solid mounting and ventilation. NEC 110.13
  7. Check for proper use, temperature and electrical ratings of terminations and splices. NEC 110.14(A) and (B)
  8. Check for enclosure markings and verify ratings of the surrounding environment. NEC 110.28
  9. Verify satisfactory working clearances, and adequate headroom around the equipment. NEC 110.26(A) and (E)
  10. Check for switching circuits and circuit directories for switchboards, panel boards and similar equipment

Further inspection is performed based on the type of electrical installation. Main categories of which are-

  1. Wiring methods and devices: 
    • Identifying the wiring method sand verifying it’s aptness for the
    • To check if all conductors of a circuit are bundled together
    • To check insulation standards, insulating bushings and grommets.
    • To check for spacing from edges of frames and from nails and screws
    • Verifying that cable trays& raceways are used solely for electrical conductors
  1. Services, feeders and branch circuits
    • Verifying that each structure has only one service line. If more than one, the presence of additional services is justified.
    • Checking clearances from building openings, roofs, swimming pools and other structures.
  1. Grounding and Bonding
    • Identify the type of grounding electrodes present on site.
    • Verify the size of grounding electrode conductor and ensure they are protected and secured.
    • Check for proper connections and grounding of the related enclosures and wiring methods for installations with grounding conductors.
  1. Dwelling units and Manufactured home sites
  2. Special occupancies
