Subject: Transient Surge Suppression

Mighty Experts of EMC,

I have a question concerning the determination of the right Transient
Suppressor to use for controlling Lightning Surges.

How do I determine the correct size and type of surge suppresser to use
(MOV's, Spark Gaps, etc...) to help my power supplies survive the surge
requirement of IEC 1000-4-5 to the AC mains?

My equipment is all single phase with idle currents below 4 Amps.

Any comments or advice would be greatly appreciated.

P.S. My questions or comments do not reflect the opinions of my company or
their lack of knowledge.  :)
