Electrical general requirements 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. Examination, Installation, and Use of Equipment

  • 1.1 Only approved conductors and equipment are used for electrical installations.
  • 1.2 Equipment is used and installed in accordance with instructions on the listing or label.
  • 1.3 All electrical equipment is free from recognized hazards that are likely to cause death or serious physical harm.

2. Splices

  • 2.1 Conductors are spliced or joined by using suitable devices or by brazing, welding, or soldering with a fusible metal or alloy.
  • 2.2 Soldered splices are first joined so as to be mechanically and electrically secure and then soldered.
  • 2.3 All splices, joints, and free ends of conductors are covered with adequate insulation.

3. Arcing Parts

  • 3.1 All parts of electrical equipment that ordinarily produce arcs, sparks, flames, or molten metal are enclosed or isolated from all combustible material.

4. Marking

  • 4.1 All electrical equipment is marked with the manufacturer’s identity.
  • 4.2 All electrical equipment is marked with the voltage, current, wattage or other ratings as necessary.
  • 4.3 These markings are durable enough to withstand the working environment.

5. Identification of Disconnecting Means and Circuits

  • 5.1 Each disconnecting means for motors and appliances is legibly marked to indicate its purpose, unless located and arranged so the purpose is evident.
  • 5.2 Each service, feeder, and branch circuit at its disconnecting means or overcurrent device is legibly marked to indicate its purpose, unless located and arranged so the purpose is evident.

6. 600 Volts, Nominal, or Less Working Space About Electric Equipment

  • 6.1 Access and working space is around electrical equipment sufficient to provide ready and safe operation and maintenance.
  • 6.2 Sufficient work clearances are maintained around all equipment operating at 600 volts or less.
  • 6.3 Required working spaces around electrical equipment are kept free of stored materials.
  • 6.4 When live parts are normally exposed on the front of switchboards or motor control centers, the working space is in front of such equipment greater than or equal to 3 feet.
  • 6.5 Illumination is provided for all working spaces around service equipment, switchboards, panel boards, and motor control centers installed indoors.
  • 6.6 A minimum headroom of 6 feet, 3 inches of working space is maintained about service equipment, switchboards, panel boards, or control centers.

7. 600 Volts, Nominal, or Less Guarding of Live Parts

  • 7.1 Live parts of electrical equipment operating at 50 volts or more are guarded against contact by approved cabinets or other forms of approved enclosures.
  • 7.2 In areas where electrical equipment may be exposed to physical damage, the enclosures or guards are arranged and of such strength to prevent such damage.
  • 7.3 All entrances to rooms or other guarded locations are containing exposed live parts marked with conspicuous warning signs forbidding unqualified persons to enter.
  • 7.4 When normally enclosed live parts are exposed for maintenance and repair, they guarded to protect unqualified persons from contact.
  • 7.5 Safety signs, safety symbols, or accident prevention tags are used where necessary to warn employees about electrical hazards.

8. Wiring Methods–General Requirements

  • 8.1 All metal raceways, cable armor, and other metal enclosures for conductors are metallically joined together into a continuous electric conductor (including connections to all boxes, fittings, and cabinets) to provide effective electrical continuity.
  • 8.2 Wiring in ducts for transporting dust, flammable vapors and exhaust from commercial-type cooking equipment is prohibited.

9. Wiring Methods–Cable Trays

  • 9.1 Only acceptable types of cables are used in cable trays.
  • 9.2 Cable tray systems are prohibited in hoistways or where they are subjected to severe physical damage.
