IEC 60320-1-2021 pdf free download – Appliance couplers for household and similar general purposes – Part 1: General requirements.
This part of lEC 60320 sets the general requirements for appliance couplers for two poles andtwo poles with earth contact and for the connection of electrical devices for household andsimilar onto the mains supply.
This document is also valid for appliance inlets/appliance outlets integrated or incorporated inappliances.
The rated voltage does not exceed 250 V(AC) and the rated current does not exceed 16 A.
Appliance couplers complying with this document are suitable for normal use at ambienttemperatures not normally exceeding +40 °C, but their average over a period of 24 h does notexceed +35 °C, with a lower limit of the ambient air temperature of -5 ℃.
Annex E provides test requirements for derating the operating current of an accessory whenused in ambient temperatures above +35 °C up to and including +90 °℃.
Appliance couplers are not suitable for:
– use in place of plug and socket-outlet systems according to lEC 60884-1;
use in place of devices for connecting luminaires (DCLs) according to IEC 61995 orluminaire supporting couplers (LsCs);
– use in place of installation couplers according to lEC 61535.
