There is quite a big difference between the two. In short the trade test is a trade qualification, in other words if you have passed a Trade Test you can call yourself an ELECTRICIAN. In the same way that a mechanic that passed a trade test can call himself/herself a MECHANIC. The same apply to a FITTER, MILLWRIGHT etc. A Wireman’s License is a registration that is done at Department of Labour. This registration is subject to certain qualifications, of which Trade Test is one, as described in the Information brochure for application as a registered person.
