Questions & Answers

Can this tool be used as a circuit breaker finder?
BySep 29, 2025
1 Answer | 
Answer This Question

The Klein Tools Cat. No. NCVT1PKIT Non-Contact Voltage and GFCI Receptacle Test Kit contains testers that provide non-contact detection and testing of AC voltage and determination of wiring condition in outlets. It does not contain a circuit breaker finder. The ET310KIT Circuit Breaker Finder Kit or ET310 Digital Circuit Breaker Finder with GFCI Outlet Tester are better options for your purpose.

        In our house I am trying to find the outlets that use this one GFI; My question, what happens if you push the check GFI button on the RT 205 on an outlet that is not on a GFI?Raymond
        ByJul 5, 2024

        Answer This Question

        If the outlet is not GFCI, pushing the button will not perform the GFCI test.

                    Purchased this Klein Tool to help me in checking whether an outlet is energized or not. I always flip the breaker when working on replacing an outlet. However, I want to make sure I flipped the right one. This works great! Klein tools are great!
