5.4 Test to determine suitability of conductors having a reduced cross-sectional area

To determine suitability of conductors having a reduced cross-sectional area, connected to

controlgear that limits the current to 2 A, the following test shall be conducted:

a) disconnect the conductors being evaluated as close as practical to the lights source in the

luminaire and attach a resistive load using minimum 1 mm cross section test leads; these

leads shall be routed out of the luminaire in a manner that will have the least impact on

temperatures within the luminaire;

b) adjust the resistive load to measure the maximum output current of the control gear,

maximum measured current shall not exceed 2,5 A;

c) with the resistive load set to draw maximum output current, conduct the thermal test in

accordance with 12.4. (see Figure 33);

d) the resistive load is then set to 0 Ω (short circuit) and the thermal test repeated in

accordance with 12.4 (see Figure 33);

In no case shall the temperature of the luminaire wiring insulation exceed the limits stated in

Table 12.2 nor shall there be any indication of damage to luminaire wiring.

requirements for basic insulation.
The minimum distances specified are based on the following parameters:
– for use up to 2 000 m above sea level;

– pollution degree 2 where normally only non-conductive pollution occurs, but occasionally a

temporary conductivity caused by condensation is to be expected;

– equipment of impulse withstand category II which is energy-consuming equipment to be

supplied from the fixed installation.

For details of pollution degrees or impulse withstand categories, IEC 60664-1 should be

consulted.

Compliance is checked by measurements made with and without conductors of the largest

cross section connected to the terminals of the luminaires. Internal wiring terminals of

luminaires shall be checked with actual conductors supplied with the luminaire fitted.

The contribution to the creepage distance of any groove less than 1 mm wide is limited to its

width.

A creepage or a clearance distance may be split into several parts. Any air gap less than

1 mm wide is ignored in calculating the total distances, unless the total clearance is less
