Put my foot fair in it there!.
On the other side of the coin, I used to work with a Dutch Electrician here, that had both a Dutch and
a German Electrical ticket and the EWRB here made him do an 8000 HR apprenticeship, for good measure.
Believe me, if this guy couldn't tell you how it worked, it either didn't exist or it wasn't electric in the first place.
It's no wonder we can't get qualified immigrants here.
