It would be great to have an electrical installation that lasts
the lifetime of the house.
Well, we also do have older houses, but from an age on I'd consider
the electrical installation a hazard.
They tend to have lower power rating, eg 6A insted of 10A, they
don't have error current breakers, they don't necessarily have
a proper earth.
Even newer houses, say 20 years old don't have the now necessary
number of outlets. And I really miss a built-in LAN, or customer
friendly cable channels for selffitting.
