Without condensate pump option
The cables have to be sized in compliance with local standards and according to the type and characteristics (e.g. Amperes) of
installation.
The specific energy allowed to flow from the circuit breaker, installed by the user, must be lower than 300,000 A
Prescriptions on the differential relay required to the user:
For special places (healthcare facilities, etc...) comply with the local regulations;
S
For ordinary places, a low sensitivity is suggested (300mA) coordinated with the value of the ground heater (IEC364): Ra
S
≤ 50/Ia (Art. 413.1.4.1, CEI 64-8);
In case of frequent over-voltages with mains impulse, it is advisable to install a selective differential and to evaluate the
S
need for adopting other devices.
(*) ATTENTION: Only universal (type B, B+) RCD protective devices are permitted.
