- adequacy connection conductors;
- accessibility for convenience operation and maintenance.2 Insulation resistance the electrical installation
The insulation resistance shall measured:
a) between live conductors taken turn two two;
Note: practice, this measurement can only carried out during erection the installation before the
connection the appliances.c. a. Testing
The following tests shall carried out where relevant and should preferably made the
following sequence:
- continuity protective conductors and the main and supplementary equipotential
bonding;
- insulation resistance the electrical installation;
- protection separation circuits;
- automatic disconnection supply;
- polarity test;
- electric strength test;
- functional tests.
The test methods described this chapter are given reference methods; other methods are
not precluded provided they give less valid results.3.
9.3.1 Continuity the protective conductors, including the main and
supplementary equipotential bonding
A continuity test shall made. During this measurement, phase and neutral conductors may connected together.3.

b) between each live conductor and earth.
In the event any test indicating failure comply, that test and any preceding test, the
results which may have been influenced the fault indicated, shall repeated after the
fault has been rectified
