Recommendations for the settings
Track voltage
Locomotive motors are - depending on the nominal size - designed for operation with a certain
track voltage. If they are driven with a track voltage significantly higher than the
recommended one, the motors will be more heavily loaded and the carbons more worn, HF
interference and brush fires will be increased.
Locomotive decoders are usually designed for a maximum track voltage of 24 V, some mini
decoders only for a track voltage of 18 V. A slight exceeding of the maximum permissible
voltage by 1 to 2 V usually does not cause damage to the locomotive decoder, but in any case
leads to significant heating. In case of an unfavourable installation situation with poor heat
dissipation, damage to the adjacent plastic parts of the locomotive can be the (undesirable)
consequence.

Maximum track current (cut-off current in case of short circuit)
The idea of using the current of 6 A, which the Booster B-6 can provide, to supply large
sections or even the complete layout is obvious. This solution, which at first glance appears to
be cost-effective, promises minimised installation effort and avoids problems that can arise
when crossing separation points between booster circuits. This idea has only one decisive
catch: in order to be able to utilise the high output current of the booster, the cut-off current,
when reached, the layout is switched off for safety reasons (e.g. in case of a short circuit) is
also increased.
The smaller the nominal size (and the more filigree rails or vehicle parts such as wheel sliders
are), the lower the cut-off current must be..

Tip: Utilise the total booster current with smaller nominal sizes
With smaller nominal sizes, the current in the booster circuit is limited to 2 to 3 A in order to
protect rails and vehicles from damage in the event of a short circuit. By using a power
splitter**, the entire output current of the booster B-6 can be utilised even with smaller
nominal sizes. The power splitter is connected between the booster's track output and the
tracks and splits the booster's power into two or three sections with a maximum current of
either 2 or 3 A.
