PRECAUTIONS
Transformers should be installed in an accessible location. Magnetic transformers generate heat and must be
installed in locations where there is free-air circulation. Electronic transformers require less space to dissipate
heat, but they too should be installed in accessible locations with free-air circulation.
For additional information, please refer to the instruction manual provided with your transformer.
Secondary Circuit Protection
Transformers are provided with circuit breakers to protect secondary circuits. The maximum size circuit breaker on a
transformer is 25 amps, but the circuit wired to the breaker MUST NOT EXCEED 20 AMPS.
There are several transformer sizes available, and different size breakers installed in them. Below is a selection of trans-
formers with their respective circuit limitations.
Larger capacity transformers with multiple out-
puts can be centrally located and feed fixtures
in either direction.

Do not exceed maximum fixture length
Do not exceed transformer output rating
Transformer Location
The maximum recommended distance between the fixture and the transformer varies, based upon the load of each fix-
ture and the size of secondary wire feeding the fixture. It is impossible to give a definitive distance without considering
all the variables. Electrical engineers and contractors can calculate these distances. Should you need guidance, consult
the factory.
