Check the continuity among:
a) earth poles of all the plugs and earth collector or node.
b) earth terminals of class I instruments (Boiler etc.) and earth collector or node.
c) main external masses (water, gas pipes etc.) and earth collector or node.
d) auxiliary external masses to the earth terminal.
ALLOWABLE VALUES
The IEE 16
th
edition standards do not give any indication on the maximum resistance
values which cannot be overcome, in order to be able to declare the positive outcome of
the continuity test.
The standard IEE 16
th
edition simply requires that the instrument in use warns the
operator if the test was not carried out with a current of at least 0.2 A and an open
circuit voltage ranging from 4 V to 24 V.
The resistance values can be calculated according to the sections and lengths of the
conductors under test, anyway if the instrument detects values of some ohm the test
can be considered as passed.
