Power Safety For Model Trains
When not using your train layout unplug the transformer. Don't walk away and
leave it plugged in and unattended as it could start a fire. If a transformer gives
off a burning odor, or expels smoke, heed these warning signs and immediately
replace it or take it in for servicing.
A loud BUZZING noise coming from a transformer could be due to the transformer's
core laminations moving. Servicing would be needed as this vibration can cause
damage to insulation in contact with the moving metal.
Transformer Circuit Breaker
A transformer's circuit breaker can trip occasionally. If this happens simply
unplug the transformer and let it cool off. The transformer will usually work again
after it has cooled down. However, if the transformer continues to trip without a
load, it will need servicing to fix the problem.
One more thing; NEVER use a transformer with a damaged, split, or cracked power
cord. If in doubt have the transformer serviced immediately.
