Gidday there Adam,
Welcome to the group!. [Linked Image]
I'd like to say that there is no way that wiring supplying that unit will carry the current required to operate it.
We have the same units over here in New Zealand and nothing short of 6mm2 wire will do for a set-up like this.
I'd also be interested to see what sort of fusing was used at the feeding end. [Linked Image]
