I've been working on my kitchen where the old electric range was wired directly to the electrical wiring (6-2) coming from the wall. I wanted to add an outlet for the new electric range so I bought one to do so. Before installing I noticed that the outlet says its ungrounded. Being the dryer has the same oulet I proceeded to pulling it out to see where the ground wire was placed. The dryer outlet showed the same 6-2 wire with the black and white wire connected to the two top angled terminals, and the ground wire connected to the bottom terminal. Now knowing this, I then wired the new range outlet the same, but when I turned the breaker back on it arced and tripped. My thoughts were that this happened because i connected the bare ground wire, so i disconnected it and ttyed the breaker again but nothing. Then, I diconnected the black and white wires, the breaker still wont turn back on. I almost positve the breaker is blown, so I will be replacing that. Should I have done anything different? Should I replace the 6-2 with 6-3 when i replace the breaker? If not, what should be done so the new breaker doesn't blow?
