Will this work with two prong (non-grounded) outlets?
1948226
Yes, it will work with 2 prong circuits . The meter itself has 3 prongs, so to plug it into a 2 prong outlet, you'll have to use an adapter or suitable 2 wire extension cord . The prongs on the meter are not polarized ( i.e. they're the same size) which makes plugging in a 2 wire extension cord easier.

An excellent question, and one that I neglected to include in my review. It has a 3-prong plug, and the only way it would work with a no-ground socket is if you plug a no-ground extension cord into the socket to which the device (refrigerator, computer, whatever) was plugged FIRST, then plug the meter into the other end of the extension cord. The extension cord female end would have to have a "straight-in" opening, not like those with plug holes on the side, and the max height of the plug would have to be 7/8" or less to avoid running into the ground prong. Alternatively, you could cut the grounding prong off. An excellent question, and one that I neglected to include in my review.

Hi I believe it will work with two on an outlet. I don't have two to try it, but the design is SLIM. For the price its feasible to purchase two just because the cords are handy. But of course that's up to you. Good luck, hope I've helped.

Yes it can. If that is your only requirement, I'd recommend getting a "3-Prong to 2-Prong adapter" (search on Amazon) since that way you can ground the prong to the house ground via the outlet. It's safer and cheaper.

I don't believe it will work because the surge protector has a 3-prong plug and I do think you need the third prong to ground the strip. However, I am no electrician and you may want to get a second opinion. Sorry I wasn't very helpful.

As previously mentioned by E. Allen, you could use an ungrounded (two-prong) to grounded (three-prong) adapter to plug into the two-prong lamp socket adapter, such as CableWholesale Cable Wholesale 3 Prong to 2 Prong Grounding Converter (30W1-32200) (strictly speaking, the latter adapter is meant for a grounded receptacle lacking a ground prong...)

It has three 2-pronged sockets. You'll need to get a grounded-socket adapter for 3-pronged plugs.

Both ends are 3-prong plugs. A 2-prong could be plugged into it but need a 3-prong wall connect.

On the back side there is one 3-prong plug, so it would not fit into a 2-prong (non-grounded) outlet.

YES,it has a second plastic ground prong to help hold it in place with a double outlet and you can just clip or break it off and it will work fine in a single outlet.

Yes, my lamp is two prong and works just fine. I'm an electrical engineer who specializes in safety and there is not a problem using a polarized (two prong) lamp plug in the grounded (three prong) receptacle.

If the outlet is a grounded 110-120 V/AC receptacle, you shouldn't have any problems.

No, as this device is designed to cover existing grounded duplexes only. You can only use this device with a three-prong outlet.

Two prong is fine as long as it's polarized which I believe all cords are these days. I just cut an extension cord in half and stripped the bare wires back. The wire that goes to the larger size plug is the ground so be sure to get that right when connecting to the unit.

Yes it will. It's nice that it has the 2 prong or three prong option because it varies from place to place. Although note that the three prong is not grounded, one of the three on this item is plastic.

In the US, you should be able to plug in two prong cables, power converters, etc. The third prong is for ground, so what ever you plug in with a two prong connector will simply not have a dedicated ground. But that should be ok, not everything needs a ground. If you are not in the US, or your house is not wired with three prong outlets, then you will not be able to use these cables and should return them.

I think so ye, I don't see why not. It works in every two prong outlet I've come accross

It can work for and outlet with the 2 screws but for me i could only attach it with one of the 2 screws. This is designed for a plug with two outlets and one center screw holding it on.
