I'm hooking up a dishwasher and failed to check wiring before I removed the old one.
Black - Red = 120v Black - White = 120v Red - White = 0v.
So obviously Red and white are Neutral and Ground. How can I tell? If the Red were Green or Bare, I wouldn't worry, but seeing as the original installer used the wrong wire, I need to question everything.
Is there a simple way of telling the two apart? Keep in mind that I'm in Canada, where the code does not allow grounding to Neutral.
-- Resolved. I ended up tracing back to the panel, Opening the panel and seeing that Red went into the rat's nest of bare copper. So, IN THIS CASE ONLY, Red was ground.
However, this leads us to the greater problem of Contractors using non-standard parts because they happen to be laying around. If I couldn't get to the panel, how could I determine the difference. I was think that a continuity check between a known ground and (test)neutral should be open, and known ground to test ground should be closed. Is that a correct assumption?
