BS 1363-4:1995+A4:2012

13 A plugs, socket-outlets, adaptors and connection units. Specification for 13 A fused connection units switched and unswitched | Status: Withdrawn, Superseded

1 Scope This part of BS 1363 specifies requirements for 13A fused fixed connection units for household, commercial and light industrial purposes, with particular reference to safety in normal use. The connection units are suitable for the connection of appliances, in a.c. circuits only, operating at voltages not exceeding 250 V r.m.s at 50 Hz. Requirements are specified for connection units incorporating a fuse-link complying with BS 1362:1973. Requirements are specified for 13 A connection units with or without associated controlling switches, for flush mounting in suitable enclosures, e.g. boxes complying with BS 4662:1970, or for surface or panel mounting. Connection units are intended for use with cables complying with BS 6004:2000 having copper conductors. Connection units with cord outlets are additionally intended for use with flexible cords, complying with BS 6500:2000 on the load (output) side. Connection units containing devices other than fuse-links, switches and indicator lamps are outside the scope of this standard.

NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover.

NOTE 2 Requirements for electromagnetic compatibility are not given for the following reasons.

A connection unit does not emit intolerable electromagnetic interference since significant electromagnetic disturbances are only generated during insertion and withdrawal which are not continuous. A connection unit is mechanical by nature of construction. The product is therefore immune from electromagnetic interference.
