I had a new cooktop installed but it does not work. The unit replaced an old one and was simply plugged into the existing outlet. After checking the basics (no tripped breakers, etc), I whipped out the old multimeter and measure the voltage difference between each input. The results were surprising:
h1 - h2 = 240 (correct) h1 - N = 0 (should be 120) h2 - N = 240 (should be 120) h1 - G = 120 (correct) h2 - G = 120 (correct) N - G = 120 (should be 0) h1 = Hot 1 h2 = Hot 2 N = Neutral G = Ground (Parenthesis are what I expected to measure)
I'm obviously mis-wired, but which wires are in error?
