I've fitted 2 inside 5wks 1 x 1.5kw & 1 x 2.2Kw that have been like this and previous to these I've had possibly 3 others same. All but one came from Chai and I didn't ask for single phase only so don't know why.? Maybe they do both and when short of dual and knowing coming to UK provide single phase.? . . . . Can tell you the First one gave me that "Oh NO" sinking feeling.!.
