BS 1363-4:2016 specifies requirements for 13 A 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 conforming to 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 conforming to BS 4662:2006+A1:2009, or for surface or panel mounting.

Connection units are intended for use with cables conforming to BS 6004:2012 having copper conductors. Connection units with cable outlets are additionally intended for use with flexible cables, conforming to the relevant part of BS EN 50525 (see Annex G), on the load (output) side.

This standard does not apply to connection units incorporating screwless terminals for the connection of external conductors of the following types:

• flat quick-connect terminals;
• insulation-piercing connecting devices; and
• twist-on connecting devices.

NOTE 1 The titles of the publications referred to in this part of BS 1363 are listed in the bibliography.

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

A connection unit is mechanical by nature of construction. A connection unit does not emit intolerable electromagnetic interference and the product is immune from electromagnetic interference.
