Recommended cross section for ground wire at least half of the
section of cable phases AND shall comply with the standards of
the country (for example NFC 15100 in France).
Minimum 300 mA delayed (Type-B). When used, the residual
current earth leakage protection system must be common for
the two AC inputs (common & auxiliary mains) and installed
upstream.
