Appreciate the help I have received in relocating my washer/dryer. Electricals went smoothly.
Now the final project: I must add a duplex outlet in the bathroom where the vanity is going. Currently there is one outlet on opposite wall( not GFIC!). I removed plate and there are two whites and two blacks as well as ground. I was hoping for an open screw for the new white and black but no such luck. I really do not want to remove all the wall to trace wires. Is it OK to just add a new white and black under a screw on the existing duplex to run my new duplex? In other words I would have two whites and two blacks under each screw on one side of existing duplex and one white one black on the other side.
I have done a search and it is suggested I trace the circuit until I come to the "last" duplex which should have a vacant set of terminals for my new wiring but as I mentioned there is only one duplex in the bathroom at this time and I have no idea where the wires run to other than they disappear into the cinder block. Oh yes I will replace the duplex with GFIC per code
