4.2.3.2. Selecting the power cables
The calculation rules used to choose the power connection cable size are defined below:
- Identify the current shown on the generating set's identification plate.
- From the table below, select the circuit breaker rating directly above the current shown on the generating set's identification
plate.
- Choose the corresponding cable size.
.
Three-phase
Permitted drop in voltage = 5% / Multi-core conductors or connected single-core conductors where rating = 4X…(1) / Cable type
PVC 70°C (e.g. H07RNF) / Ambient temperature = 30°C.
