Grounding Outlets and Receptacles
Electrical Question: I just discovered that I have outlets that are not grounded, what should I do?
- I recently purchased a four unit apartment building. The electrical entrances are all brand new which made me think every thing was fine.
- A recent inspection showed that none of my outlets are grounded. Everything is wired with the old black wire.
- Two copper wires (No ground wire). Just to be clear it’s not knob and tube. It’s one wire with Positive and negative inside.
- Each apartment has it’s own entrance with a 100 master breaker. Can I simply change this breaker to a GFCI to bring it up to code or am I looking at rewiring the building.
- The previous owner obviously changed to 3 prong outlets from 2 wire. Can I change some of these back to 2 prong and if so where can you find 2 prong outlets. I’ve no desire to do this work myself.
I just want to know all my options before I bring somebody in to look. I don’t want someone to come in and do work that does not need to be done.
Thanks.

Grounding Outlets and GFI Receptacles
- Electrical Outlet Grounding and GFCI Protection
- Mike, it sounds like the electrical panel was upgraded but the rest of the circuit wiring is original, so you are correct in saying that any 3-wire outlets that were installed where a ground source is not present should be changed to 2-wire outlets.
- Grounding Electrical Outlets
- The 2-wire outlets should be available from a major hardware store or from a local electrical wholesale distributor.
- You may install GFCI outlets that have a ground prong in areas such as the kitchen or bathroom ONLY if the receptacle is identified as not being grounded by using the sticker which is included with the GFCI receptacle.
- The GFCI protection will work the same because it will still sense a fault to ground and trip off.
- Upgrading Electrical Circuit Wiring
- Installing new 3-wire cable whenever possible is always recommended for electrical circuit upgrades, or installing ground wiring that is bonded at the electrical panel is an option as well.
- All of this work is best installed by a qualified licensed electrician. Always make sure you work through your local building department and obtain the necessary permits and inspections.

10 years ago I replaced some worn outlets in my daughter’s 1920 house. The wiring was all 2-wire, no ground. I was unable to find 2-hole outlets anywhere, so I installed standard 3-hole outlets, but I filled the ground hole with hot glue so a 3-prong plug could not be inserted. I also installed a few GFCI outlets in locations that were near a sink, since they don’t need a ground to work. A few new grounded outlets were installed later, for dishwasher, computer, etc.
Hi John,
Please note that the ungrounded 2-wire outlets are still manufactured and available for future projects where a ground wire has not been installed.
