Electrical Components and Equipment for general use checklist

The professional inspection solution

You can conduct this checklist for free on the Checkbuster platform. You can use a lap-top, PC or the free inspection App

1. Cabinets, Boxes, and Fittings

  • Conductors entering boxes, cabinets, or fittings are protected from abrasion.
  • Openings through which conductors enter are effectively closed.
  • All unused openings in cabinets, junction boxes, and fittings areeffectively closed.
  • All pull boxes, junction boxes, and fittings are provided with covers approved for that purpose.
  • Metal covers are grounded.
  • Each outlet box does have a cover, faceplate, or fixture canopy.
  • Covers of outlet boxes with holes for flexible cord pendants do have (a) bushings designed for cords to pass through holes, or (b) smooth, well-rounded surfaces on which the cords may bare.
  • All electrical wall receptacles are tight-fitting and in good condition.

2. Switches

  • Single-throw knife switches are connected so that the blades are dead when the switch is in the open position.
  • Single-throw knife switches are placed so that gravity will not cause them to close.
  • Single-throw knife switches are approved for use in the inverted position have a locking device that will keep the blades in the open position when so set.
  • Flush snap switches that are mounted in ungrounded metal boxes and located within reach of conducting surfaces do have face plates of nonconducting, noncombustible material.

3. Switchboards and Panelboards

  • Panelboards are mounted in cabinets, cutout boxes, or enclosures approved for the purpose and of the dead front type.

4. Enclosures for Damp Locations

  • Cabinets, cutout boxes, fittings, boxes, and panelboard enclosures in damp locations are installed so as to prevent moisture from accumulating within the enclosures.
  • Switches, circuit breakers, and switchboards are installed in wet locations enclosed in weatherproof enclosures.
  • Water leakage into light receptacles or fixtures (which may cause a fire hazard) is immediately repaired.

5. Conductors for General Wiring

  • All conductors are used for general wiring insulated.
  • The insulation is approved for the voltage, operating temperature, and location of use.
  • The insulated conductor is distinguished by color or other suitable means as being the grounded conductor, ungrounded conductor, or equipment grounding conductors.

6. Flexible Cords and Cables

  • Flexible cords and cables are prohibited from being used as a substitute for fixed wiring of a structure where they are (a) attached to building surfaces; (b) concealed; (c) run through holes in walls, ceilings, or floors; or (d) run through doorways, windows, or similar openings.
  • Flexible cords are used only in continuous lengths without splices or tap.
  • Flexible cords are connected to devices and fittings so strain relief is provided to prevent pull from being directly transmitted to joints or terminal screws.
  • All wires are located away from walking areas to prevent a tripping hazard.

7. Equipment for General Use: Lighting Fixtures, Lampholders, Lamps, and Receptacles

  • Fixtures, lamp holders, lamps, rosettes, and receptacles are designed and maintained so that no live parts can expose employees to contact.
  • Portable hand lamps are supplied through flexible cords equipped with a handle of molded composition or other approved material and a substantial guard attached to the lamp holder or handle.
  • The use of multiple plug receptacles is prohibited.

8. Equipment for General Use: Receptacles, Cord Connectors, and Attachment Plugs (caps)

  • Receptacles, cord connectors, and attachment plugs are constructed so that receptacles or cord connectors will accept only an attachment plug with a voltage or current rating for which the device is intended.
  • Receptacles are installed in damp locations suitable for that location.

9. Equipment for General Use: Appliances

  • Appliances are designed and maintained so that they have no live parts normally exposed to employee contact.
  • Means are provided to disconnect each appliance.
  • Each appliance is marked with its rating in volts and amperes or volts and watts.
  • Electrical appliances are in good operational condition.

10. Equipment for General Use: Motors

  • The disconnecting means is within view from the controller.
  • The disconnecting means does disconnect the motor and the controller from all ungrounded supply conductors, and is it designed so that no pole can be operated independently.
  • Motors, motor control apparatus, and motor branch- circuit conductors are protected against overheating from motor overload or failure to start, and against short-circuits or ground faults.
  • Exposed live parts of motors and controllers are operating at 50 volts or more between terminals guarded against contact.

11. Storage Batteries

  • Sufficient diffusion and ventilation is provided to storage batteries to prevent the accumulation of explosive mixtures.
