1. The cables have to be sized in compliance with local standards and according to the type and characteristics (e.g. Ampere) of installation.
2. Value of cable size is related to PVC insulation, 40°C ambient temperature and unipolar cable type.
3. The data in the tables do not consider the absorbed current for other options not explicitly described.
4. The specic energy allowed to ow from the circuit breakers, installed by the user, must be lower than 300.000A

x s.
5. Prescriptions on the dierential relay required to the user:
• For special places (healthcare facilities, etc...) comply with the local regulations;
• For ordinary places, a low sensitivity is suggested (300mA) coordinated with the value of the ground heater (IEC 364): Ra ≤ 50/Ia (Art.413.1.4.1,
CEI 64-8 or IEC60364-4-45);
• In case of frequent over-voltages with mains impulse, it is advisable to install a selective dierential and to evaluate the need for adopting other
devices.
