Sample Specification

L830/831 FAA Isolating Transformers


Transformers with features not listed in FAA AC 150/5345-47A cannot be FAA certified and therefore this requirement should not be included in your specification. This would include:
• All earthed (grounded) transformers
• Ratings such as 150W, 400W


Comparison of TPR with Neoprene


The FAA limit is 20 micro amps, which may have been appropriate when this specification was written, but is unnecessarily high for today's state-of-the-art transformers.
