Requirements for couplers with particular reference to safety and interchangeability. Suitable for connection to Class II portable appliances, indoor and outdoor use at voltages not exceeding 250 V at 50 Hz. Weather-resistant to IPX4.

This British Standard specifies requirements for 6/10 A two-pole, polarized couplers for household, commercial and light industrial equipment with particular reference to safety and interchangeability in normal use. This standard applies to couplers which are suitable for the connection of the supply voltage to Class II portable appliances and are intended for indoor and outdoor use operating at voltages not exceeding 250 V. They are capable of safe operation in conditions of splashing water as defined by IPX4 in BS 5490 and are intended for use with circular type insulated and sheathed flexible cords and cables complying with Tables 6, 9 and 16 of BS 6500:1984, having conductor cross-sectional areas of 0.5 mm², 0.75 mm² or 1.0 mm². Couplers are suitable for use at an ambient temperature of − 5 °C to 40 °C, the average value over a 24 h period not exceeding 35 °C.

Requirements are specified for rewirable and non-rewirable connectors and also for rewirable and non-rewirable inlets.

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