Minimum Recommended Wire Size (note 2)
Maximum Wire Size (note 3)
Note 1:
Short-circuit current ratings are referred to a 0.25 s duration of short circuit.
Note 2:
Correct wire sizing must take into account the actual ambient temperature of the installation and the protection device insta lled on-site.
Recommended wire size is made according to standard EN60204-1 – Table 6.E with the following assumptions:
- Recommended protection devices (fuses)
- 70°C PVC stranded copper conductors
- 40°C ambient temperature
Wire sizing is different as installation and operation conditions are different from the above mentioned values. The voltage drop from the
point of supply to the load must not exceed 5% of the nominal voltage under normal operating conditions. In order to co mply with this
requirement, it can be necessary to use conductors having a larger cross-sectional area than the minimum value reported on the above
table.
Note 3:
Maximum wire size is the maximum allowed by the disconnect switch terminals. In case a larger conductor size is needed, conta ct
factory for asking special incoming lugs.
