The plugs are suitable for the connection of portable appliances, sound-vision equipment, luminaries, etc. in a.c. circuits only, operating at voltages not exceeding 250 V r.m.s. at 50 Hz.Also specifies requirements for plugs incorporating a fuse link complying with SS 167. The plugs may be rewirable or non-rewirable complete with flexible cord. Two categories of plugs are specified covering normal and rough use. Rewirable plugs are intended for use with flexible cords complying with SS 358-5 or IEC 60227-5 having conductor cross-sectional areas from 0.5 mm2 to 1.5 mm2 inclusive.Non-rewirable plugs are intended for use with flexible cords having conductor cross-sectional areas not exceeding 1.5 mm2.also applies to non-rewirable 13 A plugs which have the brass earth pin replaced with a similarly dimensional protrusion made of insulating material designated as an insulated shutter opening device (ISOD) designed to operate the shutter mechanism of a socket-outlet conforming to SS 145-2.Plugs containing switches and devices other than indicator lamps are outside the scope of this part of SS 145.
