Based on our experience, a typical HO scale 5 Amp system can support up to 10 operators
using a 12-14 AWG bus and 20 AWG feeders. Many users overestimate the amount of
Booster power needed. Try using the PSXX Series first. If your DCC Booster overloads
from excess current draw, you need to add an extra DCC Booster to support the
concentration of trains in this location. By dividing a layout into power districts in this
manner, and using a combination of boosters and circuit breakers, you can make the most
efficient use of available power on any mid-size or large-size layout.
Another thing you want to keep in mind while designing power districts is how each district
is used. In a yard area, for example, there is a higher risk of derailments occurring with
their associated shorts. You might want to isolate this area into a separate district so that
a short in the yard will not stop mainline operations.
D. PSXX-1, 2, 3 Wiring
Wire to the PSXX should be heavy enough to carry the current efficiently. The size of
wire depends on your scale. Too much resistance in the wire or rails can result in
faulty short sensing, voltage drop and poor performance. At a minimum, we
recommend the following stranded gauge wires to prevent potential problems:
●
N Scale 18 AWG bus, 22 AWG rail feeders
●
HO Scale 14 AWG bus, 18 AWG rail feeders
●
O Scale 12 AWG bus, 16 AWG rail feeders
We recommend using stranded pair wire such as speaker or lamp cord wire for bus
wiring. If you’re using two individual stranded wires, make sure to twist the wire 4 to 6
