Questions about Electrical Codes for Wiring Outlets



Questions about Residential Electrical Wiring Codes for Outlets


Question from Grant, a Homeowner in Portland, Oregon

When upgrading old outlet circuit wiring with new wire can the old wires be capped off?

I have old ungrounded wiring on the second floor of my house. I would like to replace the old wiring on each outlet with Romex that I am able to fish down from the attic. The existing wiring to each outlet comes in from under the floorboards, so I can’t really access it to disconnect from the power source without tearing up the ceiling below. My question: is it OK to just cap and tape the ends of the old wires, and leave them in the outlet box along with the outlet and new wire? Is there any danger in leaving a “live” wire in there, even though it would never have current running through it again? All the wire runs terminate at the outlet. If I can’t leave it in there, what should I do?

Dave’s Answer:

Grant, when installing new circuit wiring to replace old ungrounded wiring it is best to remove the old wiring. However, when that is not possible then capping off the old wires with either electrical tape or wire connectors is OK. Keep in mind that the outlet box must be large enough for all of the wires and the outlet.


Specific Project:
Electrical Outlets in a Basement located in an Industrial Building

Question from Scott in Milwaukee, Wisconsin asks:

What is the code for the Outlet Ground?

What is the code for 110 vac outlets; should the outlet be positioned with the ground up or the ground down?

Dave’s Answer:
At this time the NEC Code does not specify the orientation of the ground for a 110 vac outlet.
However specific projects may fall within other codes and guidelines.
For Example: Healthcare facilities within the OSHPD jurisdiction in California require that the outlet ground is to be positioned up.

Be sure to check with your local codes, or plan set for the project you are working on to see if there is a clear specification.

I have had some homeowners request ground up for all outlets for a few custom home projects as their personal preference.





Question:
Can a bathroom outlet circuit be used for a bedroom outlet?
Josh from Seattle, Washington asks:
I would like to install a new switched outlet in my closet. The closet shares a wall with the bathroom which has a receptacle. I’d like to use the existing bathroom receptacle power for the new switched receptacle but have read that it’s not allowed according to NEC code.

The house is a 2007 townhouse. The existing bathroom receptacle does not have the breaker buttons I’m used to seeing for water areas, so I am assuming it’s a special power source?

Is doing something like this to compliant with the NEC national code?

Answer:
The bathroom circuit should not be used for the bedroom outlet as you have described. It is best to branch off of the existing bedroom outlet circuit instead in order to keep these rooms isolated from each other.
