4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided  in addition, where applicable):  13 A 
plugs, socket-outlets, adaptors and connection units Part 4: Switched and unswitched 13 A 
fused connection units - Spec ification (ICS  29.120.30). 
5. Title, number of pages and language(s) of the notified document:  13 A plugs, 
socket-outlets, adaptors and connection units Part 4: Switched and unswitched 13 A fused 
connection units - Specification (40 pages in English).  
6. Description of content:  This Part of BOS 41 specifies requirements for 13 A fused 
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 Part of BOS 41. 
NOTE 1: In order to maintain safety and interchangeability with connection units it is 
necessary that these products comply with the requirements of clauses 9 and clause 13 of this Part of BOS 41. G/TBT/N/BWA/26

  NOTE 2: Requirements for electromagnetic compatibility are not given for the following 
reasons: 
- A switched or unswitched connection unit does not emit intolerable 
electromagnetic interference since significant electromagnetic disturbances are 
only generated during insertion and withdrawal, which are not continuous; 
- A switched or unswitched connection unit is mechanical by nature of construction. 
The product is therefore immune from electromagnetic interference.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  Consumer protection
