Common Questions about Socket Testers

How do I use the outlet checker?

Simply plug it into your wall socket. The indicator lights will immediately show if your outlet is correctly wired and properly grounded, ensuring it is safe and ready to use with any grounding product.

Can I use it with other brands?

Yes. Our outlet tester uses standard connection sizing and accurately measures the ground of any standard wall outlet, regardless of what brand product you plan to plug into it.

What if the lights indicate no ground?

If the tester indicates your outlet is ungrounded, you should not plug your grounding product into it. We recommend testing other outlets in your home or consulting a qualified electrician.
