How to Understand Two-Prong Outlets | Ask This Old House

In this video, Ask This Old House electrician Heath Eastman explains what two-prong receptacles are, why they’re no longer to code, and how to replace them.
SUBSCRIBE to This Old House: bit.ly/Subscrib....
What should a person do with their two-pronged outlet when so many cords have three-prongs? To answer this, Heath has to take a step back and clarify a few things. He goes through the correct terminology of an outlet, a receptacle, and a receptacle outlet. Afterwards, Heath explains that the number of prongs has more to do with the wiring behind the receptacle than it does with the receptacle itself. Pre-1960’s, homes used two conductors, but post-1960’s a third conductor was introduced for safety, the ground wire. The ground wire will safely carry a stray, potentially dangerous, current away from risk of causing a fire or electrocution. Heath then explains that replacing them can be costly if there is no ground present, as it will require rewiring the whole room or home. However, he shares another way to get a grounded, three-prong receptacle without rewiring- using a ground fault circuit interrupter (GFCI). Heath explains how the GFCI receptacle outlet works and gives some tips on how to install one.
Cost: $20 for a GFCI and $200 for professional installation
Shopping List:
GFCI outlet [amzn.to/2WsbjZb]
Cover plate [amzn.to/3usOH7j]
Tools:
Screwdriver [amzn.to/3kUsewI]
Voltage tester [amzn.to/3AYpwvY]
Terminology:
Outlet-Anything that has a power current taken out and utilized. For example: appliance outlets, smoke detector outlets, and lighting outlets.
Receptacle-Is an outlet. A contact device installed at the outlet for the attachment of an attachment plug.
Steps for installing a GFCI outlet
1. Turn off the power to the receptacle. Use a voltage tester to confirm.
2. Remove the cover plate with a screwdriver.
3. Disconnect the receptacle from the electrical box using a screwdriver.
4. Loosen the wires on the hot and neutral sides of the outlet. If the power isn’t shut off, the screws are where you’ll be shocked.
5. Remove the outlet.
6. Before installing the GFCI, make sure there is enough room in the old outlet box. If the GFCI is too big, you’ll need to purchase and install a larger box.
7. Repeat the process in reverse with the GFCI receptacle.
Resources:
Where to find it?
A room will have to be rewired if there isn’t a ground present. However, if you want to have a grounded, three-prong receptacle without rewiring, you can also use a ground fault circuit interrupter (GFCI) found at any home center.

@@bigbeef8935 If all the receptacles on a circuit are daisy chained, which is common, you only need GFCI on the first in the chain. It will sense a hot/neutral differential in any downstream receptacle and trip. Installing more than this is unnecessary and wasteful. Also, if any circuits have a refrigerator or lighting on them you should only have GFCI protection after the fridge or lighting devices.
My 1961 on slab home in Thousand Oaks had two prong receptacles. Installed GFI's on two wire wiring.....Worked fine, in the electrical code
I have a 1950's house with a mix of two prong outlets and three-prong outlets from a previous remodel. I won't lie, I did replace a couple of two-prong outlets with GFCI outlets for a home office. Not ideal, but much cheaper than trying to rewire the entire house.
The house I grew up in had 3-4 2-prong outlets left after the previous rennovation, along with some knob & tube that was still in use. To sell it we had to have the knob & tube replaced (which went to 3-prong outlets with no ground) and found that the wire behind the 2-prong outlets was modern romex with ground conductors that had simply been cut short so they didn't have to spend $10 on 3-4 new 3-prong outlets. Not as insane as having 3 circuit breakers feeding various wires into a standard 4" box but close.
I fully-grounded a metal-sheathed houseful of receptacles by ensuring the anchor & grounding of box the metal sheathed cables and GFCI/AFCI receptacles as replacements in first positions and in areas of possible humidity & moisture, then pigtailing ALL downline receptacles to their metal boxes grounding to the box, through the circuits and back to breakers.
What a great episode!! Great info. Great questions and great answers. Thanks so much!
Added to my list of things to do. luckly most outlets were redone with 3 wires. but some have old 2 wires still.
Such clear explanation! Thank you!
Great alternate for those of us in jurisdictions *cough* Chicago *cough* that require all electrical wiring to be in conduit. Now the already huge task of requiring means running conduit throughout the walls as well. This is a budget saver option for the first receptacle in every circuit!

Good video. Wish you'd have gone over 2-to-3-prong adapters though - those little $1 plugs that let a 2-prong outlet accept a 3-prong cord. They seem like most peoples' first choice in this situation and it'd be nice to talk about the safety risk of essentially ignoring the grounding wire.

The only way those adaptors serve any purpose other than smearing lipstick on a pig's face, is if the house is wired with AC cable, also known as BX, and metal boxes, found in some homes in the 40s and 50s. In that case, you may have what are known as grounded two slot receptacles. Though in that instance you might as well install a 3 slot receptacle than use a jumper from the Grounded box to the receptacle and avoid the adapter altogether.

Spending next week in a home built in 1969 with all ungrounded 600v rated pvc NM cable. Has to be one of the newest homes I seem without equipment grounds.
In my bathroom I have a motion sensor light switch. That switch uses the ground to make sure the sensor can operate with the light turned off and be able to turn on the light automatically. I have it because I am disabled and cannot always take my hand to turn it on with crutches or my hands full. I also care for a young child who is a primordial dwarf who can't reach the light switch so when he walks in the light will automatically turn on without touching the light switch. I also have a pocket door that goes into my bedroom and by current code, there should be a 3 way switch to have 2 light switches to turn on the light in 2 separate areas. The motion sensor light switch resolved the code issue there.

This is perfectly acceptable and within code because it is a level of current that does not pose any risk of electrocution. The Lutron Maestro is perhaps the most popular of these. That said, NEC 2020 eliminated this exception, but many states are not even on NEC 2020 yet. So it's a relatively recent thing that this was eliminated.

I wouldn't say he forgot to mention it. This was 5 minute segment about a solution, not a course on all available options depending how the home is wired.
My home falls into the category of partially up to date, but much of it needs rewiring to include ground conductors. I wonder if they would ever do a video commenting on the right way to do so, so we consumers know what to look for, etc, in paying to have that work done. For instance, I always wonder what (if anything) NEC says about doing so if you aren't wanting it willing to open up all your walls. In my case, I've wondered if it would be possible to fish new conductors through the wall spaces from my basement... Anybody out there faced a similar situation?

My 1953 house has grounded wire run to all of the outlets, but it appears the electricians must have grabbed onto it and ripped out / broke off the light gauge ground wire somewhere down inside of the sheathing while installing the receptacles.

Good video. I don’t think it was mentioned if every single two prong receptacle HAS to be replaced with an AFCI/GFCI three prong receptacle. Would it be best if the new code compliant receptacle be installed on the most upstream outlet of the circuit and have the rest of the receptacles on the load side? In doing so, one would be saving a lot of money…or is it best to replace ALL receptacles with an gfci/afci? Thank you.

Sure, an equipment ground and grounded conductor (aka neutral) can both operate an appliance or provide a low resistance path for fault current, but with an open neutral just about anywhere, that old set-up becomes a problem real fast.

There was wrong info in this video. Electricity does not "take the path of least resistance". If that were true we could not have more than 1 house on a circuit powered up at a time. It takes all paths proportionately to the resistance.
I would still want a ground line. The problem with ungrounded GFCI/AFCI is that an appliance chassis can be hot right up to the moment you touch it. That means YOU trip the GFCI in a fault event. Depending on current path it can still be a lethal shock; these things are mechanical switches and they do have a reaction time.

Lets clear something up. That is not the outlet. That is the receptacle that is attached to the outlet. See NEC definitions for receptacle. Receptacle: A contact device installed at the outlet for the connection of an attachment plug, or direct connection of electrical utilization equipment designed to mate with the corresponding contact device. Lets say that again, it is a contact device installed at the outlet and not the outlet itself. Receptacle Outlet: An outlet where one or more receptacles are installed.( not the receptacle itself, but the outlet the receptacle is attached to)
He didn't even use an original 2-prong outlet
Designed in the 1900’s and hardly any change in that design since then . And not much protection for the terminations.
The world should just adopt the superior BS1363 standard 😎
Hi, I watch a lot of you tube and I am always horrified when I see two pronged outlets being installed, here in the UK we went over to three prongs in the 1940’s and although the shape of the prongs has gone from round to rectangle we still have the ground wire and take the added protection of using a cover for anywhere the ground is open like to a switch etc. although I think the use of three wirers is better I still see two pronged outlets being installed in new builds.
It’s only 110 volts though. A minor shock.

On a side note, (great video by the way. My last house was cursed with those horrible "receptacles"), I would actually pay good money to see Kevin O'Connor do a Donald Trump impersonation!
Or be the person who worked on my house and say away screw grounds are for babies, getting shocked adds a little buzz to your day.
They already explained in this video everything about 2-prong outlets, so now a tutorial on “how to understand” is not needed anymore.
Just use a 3-Prong to 2-Prong Adapter. 😂

How can you not talk about the grounding clips in the box?? That plus a new set of receptacles are WAY cheaper than a GFCI at every outlet point!!!!

Grounding through the box doesn't work if your wiring is not BX/AC or conduit...which many houses aren't

If the box is not grounded, which it wouldn’t be in a two wire system, a grounding clip does absolutely nothing.

@@shockcoach Ok, false. It's why they SELL the grounding clips. Many/most 2 prong boxes are actually grounded, given their construction and that many/most of them used the old metal wrapped wires. Honestly, why do you think they even sell them? LOL

@@allenellisdewitt clips work only if the box is grounded. If you have a 394 wiring method, your box is very unlikely to be grounded. Therefore a clip to a three prong receptacle creates a very dangerous situation. Also, if you have the first generation NM with no ground, you end up in the same boat. Just because they sell something, doesn’t mean it’s a cure all.
Much easier to just break the ground prong off those cords
why American doesn't use universal plug adapter instead of changing three prong outlets? Maybe their wire standard is different than Asian country.

Sure but for Europe (or France anyways) it’s been mandatory for all new construction since forever, and very much recommended when you sell a property, (since when it’s not done, the price can be bargained). My guess is, and I’m sorry to get geo-political, the accidents and care for injuries cost a lot of money to the social security system, so that’s why legislation is past to advice on solutions. In the US, the insurances are almighty, the state has difficulties voting laws about the an individuals obligations.

What a lot of complicated nonsense for something that merely requires an obvious and simple fix --- just drill a round hole into the outlet below the slots! :P :P :P
Don't be like my brother in law and just pry the ground prong off the plug. Use a ground lifter instead! It isn't safer, of course, but hey, ya know, this isn't horticultural advice.
