I had two of these units, one on each end of an ethernet run between two side-by-side buildings. The electrical service to one of the buildings went haywire when the Power Company's Neutral wire open-circuited at the transformer, making it essentially ungrounded. These units ensured no damage to my equipment, even though they both got warm enough to deform their plastic housings.Use these anytime you have an etherent data connection that runs outside.
