21、Uncontrolled Copy, (c) BSIBS 1363-4:1995 BSI 9 October 2003 1 1 Scope This part of BS 1363 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 th
22、e 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 controll
23、ing 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
24、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
25、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 continuo
26、us. A connection unit is mechanical by nature of construction. The product is therefore immune from electromagnetic interference. 2 Conditions of use Fused connection units shall be suitable for use under the following conditions: a) an ambient temperature in the range p5 C to +40 C, the average val
27、ue over 24 h not exceeding 25 C; NOTE Under normal conditions of use, the available cooling air is subject to natural atmospheric variations of temperature and hence the peak temperature occurs only occasionally during the hot season, and on those days when it does occur it does not persist for leng
28、thy periods. b) a situation not subject to exposure to direct radiation from the sun or other source of heat likely to raise temperatures above the limits specified in a); c) an altitude not exceeding 2 000 m above sea level; d) an atmosphere not subject to abnormal pollution by smoke, chemical fume
29、s, rain, spray, prolonged periods of high humidity or other abnormal conditions. This is equivalent to pollution degree 2, see Annex E, and overvoltage category III, see Annex D. 3 Terms and definitions For the purposes of this British Standard the following definitions apply. NOTE Where the terms v
30、oltage and current are used, they imply r.m.s values, unless otherwise stated. 3.1 fused connection unit a device associated with the fixed wiring of an installation by which appliances may be connected, and having provision for a replaceable cartridge fuse-link 3.2 cord outlet connection unit a fix
