How can I tell if my oven/cooktop were wired with 3 phases as requested?
Hi, our build is a couple of years old and originally had planned for gas cooktop. We changed our minds with plenty of notice but Builder plumbed in gas pipes anyway and electrician caught unawares. He said something along the lines of good thing I used enough wire... But I suspect he single phased it anyway. How can I tell? In the electrical box the 3 phase a/c has a different switch with 3 switches in 1 but I don't see anything like that for the stove. If it is indeed single phase, am I missing much? The cooktop doesn't behave the way I would expect, with lots of switching on and off at lower temps (just the delay getting longer with lower power). Also, if it is single phase and there are clear benefits to wiring it 3 phase how hard and expensive would it be?
