After many pitfalls, I have gotten my new dryer working. It's a Kenmore 81182 electric dryer. (Manual from sears; Sears website). Very long story short, the neutral wire at the breaker box wasn't tight, at all, not in the least (how my previous dryer ran 10 years is a mystery).
Got that squared away, but I am wondering if the 30amp dryer should be on a dedicated 50amp breaker. I had it off for two days and noticed all other appliances working in the house (fridge, washer, dishwasher, oven, stove, central heat/air). The panel at the box is not labelled, but a nice little piece of cardboard inside the box labels the slot "dryer".
Shouldn't this appliance be a 30amp breaker? Or am I misreading "minimum circuit rating = 30amp"? Hope this question falls to DIY.SE.
