A valid permit establishes that the work is authorized and ties the inspection to the approved project record. Resolve a missing or expired permit through the jurisdiction's process before treating the work as ready for final approval.

Use the approved plans and specifications as the inspection baseline. They let you compare installed equipment, circuits, and layouts with the permitted design.

It identifies equipment evaluated for a stated use or condition. Verify that the installed product and its installation match that identified use; a label does not authorize every possible application.

Confirm the conductor's type, insulation, marking, permitted use, ampacity basis, and physical installation. A correct size alone is not enough if the insulation or environment is wrong.

A termination must be identified for the conductor and its temperature rating and be installed as intended. Poorly matched or loose terminations can overheat even when the conductor appears acceptable.

Establish the calculated load and the service rating, then verify that the service conductors and equipment are suitable for that load and installation.

Clearances reduce the chance that people, vehicles, structures, or other systems contact energized conductors. Check the actual routing and nearby conditions, not just the drawing.

Service equipment provides the main means to disconnect the building from the supply and contains the related service protection. Its location, accessibility, rating, and installation all matter.

It is the collection of qualifying electrodes connected to ground the electrical system. Inspect the available electrodes, their connections, and the grounding electrode conductor as one coordinated system.

The grounded conductor normally carries circuit current. The equipment grounding conductor provides a fault-current path for exposed conductive parts and normally carries current only during a fault.

Bonding joins conductive parts to create an effective fault-current path. At the service, the system grounding arrangement is intentionally connected as required; downstream connections are handled differently to avoid objectionable current.

The marking communicates the fault current available at that equipment and supports a check that equipment interrupting ratings are adequate for the installation.

Verify its location, accessibility, identification, rating, and installation. The disconnect must provide a practical, code-compliant means to isolate the service.

Grounding to earth stabilizes the system voltage reference, while bonding and equipment grounding create the low-impedance path intended to clear ground faults. Do not confuse the two functions.

A branch circuit supplies utilization equipment or outlets. A feeder carries power from the service equipment or another source to downstream distribution equipment or branch-circuit overcurrent devices.

A continuous load is treated with added capacity in conductor and overcurrent-protection sizing. Identify the load classification before applying the calculation rules for the selected code cycle.

The code's calculation method accounts for the expected demand on a system. Use the applicable method and demand rules rather than assuming every connected load operates at full load simultaneously.

It opens a circuit when current reaches a level that could damage conductors or equipment. It is not a substitute for equipment-grounding, bonding, or a correctly sized conductor.

Check that the device's type, rating, location, and installation work with the circuit conductors and the equipment served. One device selection can affect several parts of the installation.

A compliant calculation does not prove a compliant installation. Also verify routing, protection from damage, termination, environmental suitability, and required equipment grounding.

It is the intentionally bonded, low-impedance path that carries fault current back to the source so the overcurrent device can open promptly. Earth alone is not that path.

Bonding keeps exposed conductive parts at a common potential and connects them to the fault-current path. That reduces shock risk and helps protective devices operate during a fault.

It asks whether required receptacle, lighting, switch, and GFCI-protected outlets are provided where the occupancy and installation rules require them.

A box must have enough usable volume for the conductors, devices, fittings, and splices it contains. Crowding can damage insulation and make safe connections difficult.

It identifies the circuits served so occupants and workers can isolate the correct circuit. The directory should describe the actual loads, not rely on vague or outdated labels.

Review location, access, working space, rating, enclosure condition, grounding and bonding arrangement, and the suitability of installed overcurrent devices.

A raceway is an enclosed channel for conductors; a cable is an assembly of insulated conductors with an overall construction. Each has permitted uses, support, protection, and fill considerations.

Too many or overly large conductors can make pulling difficult, damage insulation, and affect heat dissipation. Use the applicable code-cycle calculation method instead of estimating by appearance.

Confirm that the cable type is permitted for the location and is correctly supported, protected from damage, terminated, and installed with fittings made for that cable system.

Flexible cords are intended for permitted movable or connection uses. Their flexibility does not make them suitable for concealed, permanently installed, or damage-prone wiring applications.

A conduit body is part of the raceway system and may provide access for pulling or splicing only when identified for that purpose. Verify its use, fill, cover, and accessibility.

Verify the receptacle's rating, configuration, listing, grounding connection, and location are appropriate for the circuit and intended use. Physical damage and polarity are field checks too.

The luminaire, its supports, wiring, and location must be suitable for the environment and installed in accordance with its listing and instructions. A listed fixture can still be misapplied.

A correctly located disconnect allows equipment to be safely isolated for service. Verify the disconnect is suitable, accessible, and associated with the equipment it controls.

Overload protection responds to excessive motor current over time. Short-circuit and ground-fault protection addresses high fault current. Motor circuits often need both functions considered separately.

Check that the controller is suitable for the motor's voltage, phase, duty, and control function and that associated conductors and protection are coordinated with the installation.

The review includes location, ventilation, guarding, primary and secondary conductors, overcurrent protection, grounding and bonding, and the relationship of the transformer to its downstream system.

It is a location where flammable gases, vapors, liquids, combustible dusts, or fibers may create an ignition hazard. Equipment and wiring methods must be suitable for the specific classification.

An ordinary enclosure or wiring method may introduce an ignition source. Verify the equipment identification, installation method, seals where required, and match to the classified location.

Health care spaces can have additional reliability and patient-safety requirements. Identify the space classification and then apply the special electrical rules for that environment.

They can contain ignitable vapors and have location-specific electrical hazards. Inspect the wiring methods and equipment for suitability to the actual hazard zone and activity.

Bonding reduces voltage differences between conductive parts people can contact near water. It is a safety function distinct from simply connecting equipment to earth.

Review the equipment's suitability for the wet environment, wiring method, bonding, grounding, protection, and installation instructions—not only the pump connection.

Ask whether the equipment and its wiring are listed, identified, protected, and installed for their particular use and location. Special equipment often has article-specific rules beyond general wiring rules.

Emergency systems serve life-safety functions required by code, while optional standby systems are installed for owner-selected continuity or convenience. Their source, transfer, separation, and performance rules differ.

Separating emergency wiring from normal wiring helps keep a fault, fire, or maintenance problem on the normal system from disabling life-safety loads.

Each has its own circuit, cable, device, and installation requirements. Identify the system first, then verify its power source, conductor type, separation, protection, and equipment use.

Clear identification supports safe operation, maintenance, and emergency isolation. It also helps verify that the feeder shown on the plans and panel schedule is the feeder installed.

A tap conductor is a portion of a feeder that supplies downstream equipment. Its permitted length, protection, routing, and conductor sizing must be evaluated under the applicable code-cycle rules.

Wet, damp, corrosive, concealed, exposed, and damage-prone locations can require different wiring methods. Select the method based on the actual field environment, not just convenience.
