Hooking up a dryer
I recently bought a 220v washing machine, so I needed a two-outlet box so that both the washer and dryer could be plugged in. I needed to replace the 3-pin plug with a 4-pin plug so that the dryer could be plugged into the box. But even though the box is rated at 30w, it keeps tripping when I run the dryer. I have tried the dryer on both outlets, and it still trips. (The washing machine works fine.) I will admit deviating from the instructions on one matter: The instructions said that the ground wire connected to to the metal case of the outlet box must be grounded to a spike that is within five feet of the front door! Instead of this, I connected it to the ground socket in a redundant 125v outlet behind the washer. Is it tripping because of my wilful defiance, or is there some other explanation?
