I am looking for an answer to something I am lost about, hopefully I can fins some help. I recently moved into a new home. The previous owners had a gas dryer and no outlets for an electric dryer. I had the gas line removed as it was faulty, and am now trying to install an electrical line for my electric dryer. I purchased the correct 3 wire outlet, a new 220v breaker since there was not an extra one in the breaker box, and a 15ft indoor copper building wire (which is 4 wires). I wired the cable to the outlet using the 2 hot wires (red and black) and the white wire (neutral). I left the bare copper wire (ground) out as from my understanding the dryer is already grounded and this wire is not needed. then ew breaker is installed and now i need to wire the outlet to the breaker. Here is my issue. I can run the red and black wires to the breaker, no problem, but there does not appear to be an open spot on the neutral bar, where all the other white wires are running to. There is another bar directly below it, which i assume is the ground bar that has open slots. the top bar has a large black wire running from it to the outside along with the 2 main wires coming into the house. the bottom bar has a black wire that runs to a screw a few inches away on the breaker box itself. With there being no open slots for my neutral wire to go, where should i put it?
Can I put it on the bottom bar?
Can I tie it in with another neutral wire?
Perhaps one of the other neutral wires can be moved to the other bar?
Edit: I just noticed that behind the two bars at the bottom, there is a copper piece of metal right in the center that appears to connect the 2 bars, at least I assume so.
Edit 2: Just thought I would update everyone on the situation. I added a 220V 30Amp breaker to the breaker box. I ran the red and black wires to this breaker. i then moved the green wire running to the neutral bus down to the ground bus. This green wire was labeled as upstairs kitchen with its associated breaker. I checked the kitchen equipment, it is all running normally. I then hooked the white neutral wire coming from the dryer outlet into the now open spot on the neutral bar. i then turned on the breaker and my dryer appears to be working normally as well. Thank you all for the help. I will of course be updating my dryer hookups to the 4 wire standard as soon as possible, and i will probably be adding an additional neutral bar to my breaker box as well. I will update this post if i run into any problems.
