Then they are all bloody idiots!! ''Just in Case'' has no relevance in electrical design concepts!!
Couldn't agree more!
I see your point, but would argue (forgetting relevant Laws/Guidance) that a very high percentage of design is for "just in case" scenarios. Fire Alarms, Intruder Alarms, Controls, Cut-outs, E-stops, UPS, back up Generators, less abled alarms, could all be placed in the "just in case" bracket.
I like this "nanny" state of affairs as little as the next man. . .
If you can't work out that it's raining or dark, should you be driving?
Yet vehicles are coming equipped with rain/light sensors.
If you are unable to recognise if you remove a smoke alarms supply that it will no longer operate, do you deserve to live?
Yet we go to great lengths to ensure the supply will remain on, and install back up batteries.
If we carry on supporting this then our already sullied gene pool is going to become a whole lot worse!
When does it stop being a "life safety system", and become a "they are clearly imbeciles, lets protect them from their own stupidity", or indeed "just incase"?
Was it you or Tony that wrote "never underestimate the ingenuity of a stupid person"? Unfortunately this could not apply more to design - "just incase".
