Also, I had read on the Internet that any electrical engineer that can be exposed to terminals above 50 VAC or 120 VDC are required to be registered.
There are a couple of different levels for doing live work. There are Electrical Service Technicians, electricians, as well as Linesman.
The elec service tech's are for the likes of appliance techs & HVAC type technicians, that don't work in the electrical industry primarily, but are sometimes required to test, disconnect-re-connect etc.
What registration is required? Is this similar to a Professional Engineering registration or to obtaining an electrical license? Sorry about all of the questions, but the requirements are pretty confusing.
I would thing that it would be similar to obtaining an electrical license. To work in the electrical industry for reward as an electrician, you need to be registered, and have a practicing license.
To work as an Electrical Engineer, you would not be expected to do live work, but if you did have registration, you would possibly looked upon favorably.
Most of it relates to knowing the local regulations & wiring rules, we follow the Australian Standards to a certain extent.
