## WIRING METHODS, COMPONENTS, & EQUIPMENT FOR GENERAL USE - (C) Receptacles shall be of the grounding type. Unless installed in a complete metallic raceway, each branch circuit shall contain a separate equipment grounding conductor, and all receptacles shall be electrically connected to the grounding conductor. Receptacles for uses other than temporary lighting shall not be installed on branch circuits which supply temporary lighting. Receptacles shall not be connected to the same ungrounded conductor of multiwire circuits which supply temporary lighting. - (D) Disconnecting switches or plug connectors shall be installed to permit the disconnection of all ungrounded conductors of each temporary circuit. - (E) All lamps for general illumination shall be protected from accidental contact or breakage. Metal-case sockets shall be grounded. - (F) Temporary lights shall not be suspended by their electric cords unless cords and lights are designed for this means of suspension. - (G) Portable electric lighting used in wet and/or other conductive locations, as for example, drums, tanks, and vessels, shall be operated at 12 volts or less. However, 120-volt lights may be used if protected by a ground-fault circuit interrupter. - (H) A box shall be used wherever a change is made to a raceway system or a cable system which is metal clad or metal sheathed. - (I) Flexible cords and cables shall be protected from damage. Sharp corners and projections shall be avoided. Flexible cords and cables may pass through doorways or other pinch points, if protection is provided to avoid damage. - (J) Extension cord sets used with portable electric tools and appliances shall be of three-wire type and shall be designed for hard or extra-hard usage. Flexible cords used with temporary and portable lights shall be designed for hard or extrahard usage. - Note: The National Electrical Code, ANSI/NFPA 70, in Article 400, Table 400-4, lists various types of flexible cords, some of which …

However, receptacles of cord- and plugconnected arc welders may have ampere ratings not less than the minimum branch-circuit conductor ampacity. - (e) Cord connections . You must install a receptacle outlet wherever flexible cords with attachment plugs are used. Where flexible cords are permitted to be permanently connected, receptacles may be omitted. ## Table S-4--Maximum Cord- and Plug-Connected Load to Receptacle ## Table S-5--Receptacle Ratings for Various Size Circuits - Outside conductors, 600 volts, nominal, or less . The following requirements apply to branch-circuit, feeder, and service conductors rated 600 volts, nominal, or less and run outdoors as open conductors. - (a) Conductors on poles . Conductors on poles must have a separation of not less than 1 foot where not placed on racks or brackets. Conductors supported on poles must provide a horizontal climbing space not less than the following: - (i) Power conductors below communication conductors--30 inches; - (ii) Power conductors alone or above communication conductors: - (A) 300 volts or less--24 inches; - (B) Over 300 volts--30 inches. - (iii) Communication conductors below power conducto…

Oregon Occupational Safety and Health Division Division 2 - (i) Portable cord- and plug-connected equipment and flexible cord sets (extension cords) shall be visually inspected before use on any shift for external defects (such as loose parts, deformed and missing pins, or damage to outer jacket or insulation) and for evidence of possible internal damage (such as pinched or crushed outer jacket). Cord- and plug-connected equipment and flexible cord sets (extension cords) which remain connected once they are put in place and are not exposed to damage need not by visually inspected until they are relocated. - (ii) If there is a defect or evidence of damage that might expose an employee to injury, the defective or damaged item shall be removed from service, and no employee may use it until repairs and tests necessary to render the equipment safe have been made. - (iii) When an attachment plug is to be connected to a receptacle (including any on a cord set), the relationship of the plug and receptacle contacts shall first be checked to ensure that they are of proper mating configurations. - (3) Grounding-type equipment. - (i) A flexible cord used with grounding-type equipment shall contain an equipment grounding conductor. - (ii) Attachment plugs and receptacles may not be connected or altered in a manner which would prevent proper continuity of the equipment grounding conductor at the point where plugs are attached to receptacles. Additionally, these devices may not be altered to allow the grounding pole of a plug to be inserted into slots intended for connection to the current-carrying conductors. - (iii) Adapters which interrupt the continuity of the equipment grounding connection may not be used. - (4) Conductive work locations. Portable electric equipment and flexible cords used in highly conductive work locations (such as those inundated with water or other conductive liquids), or in job locations where employees are likely to contact water or conductive liquids…
