Hey Chrys,
No probs.
Glad you sorted it out.
Easy to make small errors when fumbling about in the dark.
Still....it wouldn't hurt to get a larger gauge (15 Amp) cable, just to be sure.
The references to the type of cable "they" use is thus,
Cheap stuff out of China uses Aluminium strands with a very minute coating of copper.
These will not carry the required current & often fail.
Stay safe.
