B84: Inspection requirement 

Date when the measure came into force

16 December 1987 

Publication where the measure is specified

Government Notice 2286 (Government Gazette 10987) Of 16 October 1987 

Regulation where the measure is specified

Compulsory Specification For Earth Leakage Protection Units 

Country/Region applying the measure

South Africa 

The rationale of the measure

This specification covers earth leakage protection units (circuit-breakers) for use in domestic and industrial or similar electrical installations and connected to a source of alternating current supply operating at a frequency of 50 Hz, the neutral conductor of which is connected to the general mass of earth on the supply side, and subject to the following limitations:
(a) Maximum rated voltage.................................................. . . . . . 500v.
(b) Maximum rated current ....................... ................................ 100 A.
(c) Maximum rated earth leakage tripping current.. ........................30mA
(d) Ambient temperature ..................... ...................................... - 5 ̊C to +10 ̊C.

The earth leakage protection units covered by this specification are intended to reduce fire and electrocution
hazards caused by current leaking from line and neutral conductors to earth.
This specification does not cover earth leakage protection units intended for service under extreme operating
conditions such as continuous high atmospheric humidity, atmospheric pollution, mechanical vibration. mechanical shock, and excessively high or low temperatures. 

Description of the measure
