Hi Leon,

I also think the wire you purchased is too thin, at 0.75mm diam, that has a cross sectional area of pi(r) = 3.141 x .375 .

Or approx 0.44 square mm, according to the attached PDF table that area will not support 2 Amps and only 1 amp up to 5 metres in length.

This table suggests you need an area of 1.84 square mm to carry 2 amps up to 15 metres, thicker wire if you want to go longer. Now 1.84 square mm is about 1.5mm in diameter ( Diam = 2 (sq root Area/pi.).

P.S. If you haven't used the cable, Bunnings should exchange it or give you a refund.
