Notes:
S The cables have to be sized in compliance with local standards and according to the type and characteristics (e.g. Amperes) of installation.
S The specific power of the user --- i nstalled switch, must be lower than 300.000 (A
2
xs).
S Prescriptions on the differential relay required to the user:
S for special places (healthcare facilities, etc.) comply with the local regulations;
S For ordinary pl aces, a low sensitivity is suggested (30 mA) coordinated with the value of the ground heater (IEC 364) : Ra ≤ 50/l
a
(Art. 413.1.4.1, CEI 64 --- 8);
S In case of frequent over---voltages with mains impulse, it is advisable to install a selective differential and to evaluate the need for adopting other devices.
