This standard gives requirements and recommendations for the provision of a safe electricity supply to the consumer. 2 This standard establishes general principles for the earthing of low-voltage distribution systems of which the supply starts at the point of generation or transformation and ends at the supply earth terminal of the consumer. 3 This standard applies to distributors that operate at a voltage (a.c. or d.c.) that does not exceed 1 000 V. NOTES 1 For ease of comparison, single-phase supply connections are illustrated in the diagrams. 2 For new distributors and new services of existing distributors, only TN-C-S and TN-S system earthing should be used (see clause 5).
