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.
- 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.
