Cables sizes must comply with local wiring regulations and are the responsibility of the
installer. The cable sizes shown in Table 4-3 and Table 4-4 are for guidance only.
The current-carrying capacity of cables is affected by the mounting method and grouping.
A larger cable size may be required to avoid excessive temperature or voltage drop.
