1 Scope

This document sets the general and dimensional interchangeability requirements for plugs, socket-outlets, connectors and appliance inlets with arcuate contacts of standardized configurations (hereinafter referred to as accessories), with a rated operating voltage not exceeding 600 V AC at a frequency of 50 Hz and

60 Hz

This document applies to accessories for use when the ambient temperature is normally within the range of –25 °C to +40 °C. These accessories are intended to be connected to cables of copper or copper alloy only.

Interchangeability requirements are defined for IP20 accessories.

NOTE The conditions of use indoors are based on the limitations given by IEC 60364-5-51:2005, Table 51A, AD1.

Socket-outlets or appliance inlets incorporated in or fixed to electrical equipment are within the scope of this document.

1.1 All devices are intended for connection to a branch circuit for use in accordance with the National Electrical Code, ANSI/NFPA 70.

1.2 For Arcuate Blade (locking-type configuration) devices rated 20 or 30 of the non-grounding type or devices rated 15, 50 or 60 A grounding or non-grounding are investigated to the Standard for Attachment Plugs, Cord Connectors and Receptacles with Arcuate (Locking Type) Contacts, UL 498D.

1.3 For Arcuate Blade (locking-type configuration) devices with Enclosure Types for Environmental Protection, refer to the Standard for Attachment Plugs, Cord Connectors and Receptacles – Enclosure Types for Environmental Protection, UL 498E.

1.4 For Arcuate Blade (locking-type configuration) of the Marine Shore Power Inlets type, refer to the Standard for Marine Shore Power Inlets, UL 498M.

1.5 Attachment plugs and cord connectors on the non-rewirable (molded-on) type are not covered by the scope of this Standard. Refer to the Standard for Cord Sets and Power Supply Cords, UL 817.

1.6 This Standard does not directly apply to, but supplements the following standards:

1. a) Straight-blade attachment plugs, receptacles, cord connectors, and inlets, are covered by the Standard for Attachment Plugs and Receptacles, UL 498;

2. b) Current taps and adapters not provided with wiring terminals for flexible cord covered by the Standard for Current Taps and Adapters, UL 498A;

3. c) Devices with contacts of the pin and sleeve type are covered by the Standard for Plugs, Receptacles and Cable Connectors of the Pin-and-Sleeve Type, UL 1682;

4. d) Single and multipole connectors intended for factory assembly to copper or copper alloy conductors or printed wiring boards for use in data, signal, control and power applications within and between electrical equipment, covered by the Standard for Component Connectors for Use in Data, Signal, Control and Power Applications, UL 1977;

5. e) Devices intended for installation and use in hazardous (classified) locations in accordance with the National Electrical Code, ANSI/NFPA 70, covered by the Standard for Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations, UL 1203; and

6. f) Single pole locking-type separable connectors, covered by the Standard for Single Pole Locking-Type Separable Connectors, UL 1691.
