It's going to take me a while to wrap my head around this one.

Trying to put my mind in the same place as those who wrote the regulations.

Al I can say is one cannot really blame electricians for not interpreting the regulations correctly.

A point of control to turn off the power to an installation is sometimes a point of control, other times not, and when it's not, it is similar to one, but not one.

All somewhat confusing and I'll need a lot more time to try and understand it all.
