The following tables provide quick order of magnitude fault levels for a a range of typical low voltage situations.

How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...

It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow.   As it turns out I last week...
