How much do outlet testers cost?

An outlet tester can cost between $10 – $400. There is a wide range in the sophistication of these tools. The one above costs $15 at Amazon. A person without electrical experience can use this tool to test outlets. If you need to complete repairs you should consider hiring a qualified contractor. So what does a fancy outlet tester look like?

  2. Open Neutral
