This custom-made EarthShield grounding adapter is made for use in USA and Canadian outlets.

It has built-in 10,000 Ohm safety resistor suited for grounding (in addition to the safety resistor that is fitted inside of our EarthShield cords).

We recommend that you test your outlet is correctly earthed using an outlet tester before using your grounding adapter and products.

This adapter has 2 inputs so you can connect two products, or one product and a multimeter or product tester.
