IEC 60670-1 Boxes enclosures for electrical accessories for household and similar fixed electrical installations

Introduction

This Documents(EN 60670-1:2021) consists of the text of IEC 60670-1:2015 prepared by SC 23B “Plugs, socket-outlets and switches” of IEC/TC 23″ Electrical accessories”.

This part of IEC60670 applies to boxes, enclosures and parts of enclosures (hereafter called “boxes” and enclosures”) for electrical accessories with a rated voltage not exceeding 1000V a.c. and 1500V d.c intended for household or similiar fixed electrical installations, either indoors or outdoors.

Boxes and enclosures complying with this standard are suitable for use at ambient temperature not normally exceeding +40℃, but their average over a period of 24h does not exceed +35 ℃, with a lower limit of ambient air temperature of -5℃.
