From an "out of town" perspective, we work on one Registration, Electrician.
You have to pass the same exam as everyone else and that puts you in the same boat as your peers.
No-one has anything over anyone apart from years of experience.
Over here you can work on any system or voltage as long as it is not carried on poles or carries HV or above that.
----------------------------------------------
Disregard that above statement, as far as security wiring goes, that is a whole different kettle of fish, most security installers here don't hold Electrical Registration as Electricians, a lot of Electricians here wouldn't know where to start with a Security or Fire Alarm system.
----------------------------------------------
And yes, we have the multi-guess exams here these days too.
