There is no SURGE protection no this beast!
Now let me think!
The Great Technological innovation, is powered by 240VAC, straight off the the power grid, which is susceptible to "Surges" when Lightning activity is taking place in the neighborhood, and transients generated from power outrages being restored, and I see no visible surge protection for the delicate circuitry on the motherboard, or elsewhere in the parts breakdown.
In addition power and signals for the motherboard circuitry is shuttled around by pressure contacts and "Zebra" connectors in an environment exposed to to the temperatures and humidity of the OUTDOORS environment.
Is this some kind of a mystical device, like the "Flux capacitor" of the back in the future slapstick comedy?
Or is it more likely the Elster folks are jesting with the Ignorance of the general public?
Let me ask the question?
What is the MTBF of this toy?
Thirty Seconds after Installation to fire conflagration?
and sixty seconds to errant metering data? Whichever comes first!
I have seen Christmas toys designed better that this abomination of Electronic design Principles.
