Conductor losses

Take into account the voltage drop on the supply line when planning a system. Avoid the voltage drop being so high that the supply voltage at the box lies below the minimum nominal voltage.
Variations in the voltage of the power supply unit must also be taken into account.

For 2.5 mm²: adapter required

Pre-assembled hybrid cables with B17 connectors are available only with a wire cross-section of 1.5 mm².
If you want to use a cable with a cross-section area of 2.5 mm², you will need an adapter cable, such as one from B17 to B23.
