Specifications
For a 1+1 parallel system for redundancy, the parallel maintenance bypass panel can support a load of up to 120 kW/kVA as long as the neutral current (250 A) is not exceeded:

at 380 V, the maximum neutral current capability is reached with a 95 kVA nonlinear load.

at 400 V, the maximum neutral current capability is reached with a 100 kVA nonlinear load.
For a 2+0 parallel system for capacity, the parallel maintenance bypass panel can support a load of up to 240 kW/kVA as long as the neutral current (500 A) is not exceeded:

at 380 V, the maximum neutral current capability is reached with a 190 kVA nonlinear load.

at 400 V, the maximum neutral current capability is reached with a 200 kVA nonlinear load.

Recommended Cable Sizes
DANGER 

hazard of electric shock, explosion, or arc flash
All wiring must comply with all applicable national and/or electrical codes.
Failure to follow these instructions will result in death or serious injury.

Cable sizes in this manual are based on table B.52.5 of IEC 60364552 with the following assertions:

90 °C conductors

An ambient temperature of 30 °C

Use of copper or aluminum conductors

Installation method C
PE size is based on table 54.2 of IEC 60364454.
If the ambient temperature is greater than 30 °C, larger conductors are to be selected in accordance with the correction factors of the IEC. Aluminum cables are not recommended for ambient temperatures over 30 °C.
