Organization: SNZ
Publication Date: 5 November 2007
Status: active
Page Count: 38
scope:

This Standard sets out some of the common inspection and test methods required to verify that a low voltage, multiple earthed neutral (MEN) (TN-C-S) electrical installation complies with safety requirements for the prevention of fire, or a person or livestock from sustaining an electric shock.

The tests detailed in this Standard are as follows:

(a) Earthing system continuity and resistance;

(b) Insulation resistance;

(c) Polarity;

(d) Correct circuit connections;

(e) Phase sequence;

(f) Fault-loop impedance;

(g) Verification of operation of residual current devices;

(h) Earth electrode resistance;

(i) Touch voltage; and

(j) Continuity and resistance of the incoming neutral.

The Standard illustrates testing procedures for an electrical installation connected to an MEN system of earthing. The equipment and methods:

(k) Are not exclusive and other equipment and methods may be used;

(l) May be applied to types of low voltage installations other than MEN; and

(m) May be applied to work affecting only part of an installation, e.g. alterations, additions or repairs.
