Electricity - SDMO RENTAL POWER R550C2 User And Maintenance Manual

3.4. Electricity

a) Connections - general information
As with low voltage electrical installations, use and maintenance is governed by standard NFC 15.100 (France) or by the standards in
the relevant country, based on international standard IEC 60364-6-61.
They must also adhere to the regulations in the NFC 15.401 application guide (France) or to the regulations and standards in the
relevant country.
b) Power cables
These can be unipolar or multipolar according to the power of the generating set.
Power cables should preferably be installed in ducts or on a cable tray for this purpose.
The cable cross-section and number of cables should be determined according to the cable type and the current standards to be
observed in the country of installation. The choice of conductors must comply with international standard IEC 30364-5-52.
Three phase - Calculation hypothesis
Fitting method = wiring in cable runs or non perforated trays.
Permissible voltage drop = 5%
