4.2.2.1.
Earthing system principle
The
Earthing system
, or
SLT
(formerly
Neutral system
) of the electrical installation defines the situation of the generating set neutral
in relation to earth and the grounds of the electrical installation at the user end.
Our generating sets are designed to operate with the TT system (or EDF application depending on the option, for France only).
4.2.2.2.
TT
system
In the TT earthing system, automatic power cut-off via a Residual Current Device (RCD) is obligatory at the upstream part of the
installation, to ensure that personnel are protected (additionally, a maximum 30 mA device must be installed on outlet circuits).

The alternator neutral is earthed, the grounds of the user equipment have their own earth connection.
