Connectors too are not necessary fixed.
When mapped in OSM they are fixed by the location given. So I see no

Currents: Installations here do not use connectors that have a higher 
current capacity than the circuit can supply.
I think that is in the AS wiring rules, and those are legal requirements.
This helps to stop circuits being overloaded.
While this may not be the case in  some places, so OSM will need to
