2.3.3 Recommended wire sizes
Table 2.6 lists the recommended wire sizes. The recommended wire sizes for the main circuit ter-
minals for an ambient temperature of 50
C are indicated for two types of wire: HIV single wire (for the
maximum allowable temperature 75°C) (before a slash (/)) and IV single wire (for 60°C) (after a slash
(/))
