The integrity of any electrical installation once established cannot simply be taken for granted. Every electrical system, no matter how good the initial installation, undergoes changes and deterioration throughout its lifetime.

In many cases these changes are not formally planned and managed, and their cumulative effect on the overall installation can give rise to problems.
