Klein Tools ET310 AC Circuit Breaker Finder, Electric Tester With Integrated GFCI Outlet Tester

Like the design and worked well when zI tested it.

Purchased at Home Depot. What a piece of junk. (MSRP just shy of $50) There are lots of cheap $20-$30 non-branded items that do the same thing (Practically Nothing). Spend some time and flip breakers. (This takes just as long and both methods really need 2 people to go quickly.) I was expecting more. (If I find my packaging its going back.) I may still take it back to Home Depot w/o packaging. Pros: So this tool will let you plug into an actively powered receptacle & then at the breaker panel, it will give you fairly good indication of which breaker that receptacle is connected to. It includes a special transmitting poorly color coded GCFI testing tool, as if you really needed another one. (Klein RT500 $15) Cons: #1) It will not give you an indication of a live wire. (Klein NCVT-2 Non Contact Tester $20) #2) It will not connect to bare wires nor a light socket. (Klein 69411 Circuit Breaker Finder Accessory Kit $13) #3) It does not include AFCI testing. (Klein RT310 AFCI/GFCI Outlet Tester $47) #4) It does not include a bag. (Klein 69401 Multi-meter Carrying Case $10) #5) To my knowledge you cant trace a line with the breaker off. (Klein VDV500-808 Tone & Probe $70) #6) Tone generator is so weak that you cannot trace the wire path even with on exposed NM-B. #7) Trace tool did not indicate at the breaker panel that two branch circuits where linked by a poor wiring job. --more comments on items above-- #1) Not a big deal as I trust/use a FLUKE one. (But why not build into the tool?) #2) I can build this kit for $5 at the dollar store, probably cost them $2 plus $4 for packaging/shelf space. #3) I dont have an AFCI tester and I would bet most people dont either. I could have used that feature. #4) Again the bag cost them about $1 plus $4 for packaging/shelf space. #5) Wanted to use my tone & probe (Old Greenlee), but couldnt find it. This Klein tool doesnt replace a Tone/Probe. #6) This is what killed it for me. I have 4 yellow NM-B and would like to know which circuit is which. #7) Circuits linked after a GCFI. I only found b/c I tripped the wrong circuit when testing with GCFI tool.

Helps when doing outlet changes, easy double check.

It’s easy to use but it doesn’t accurate.

Found that it would give false readings on one of circuit breakers with a very loud tone. Turned that breaker off and power was still on. I then tested to a 2 in one breaker with 2 15 amp circuits using the space of one circuit breaker, the tracer did give a weak audible sound, but it was now the correct breaker. I found my other 2 in one breakers did not have this issue. Its possible somewhere wires are crossed in my old house. Just make sure you have the correct circuit breaker! Otherwise, the tracer saves a bunch of aggravation when circuits are random throughout my house. Labeling on my circuit breaker panel is Not specific to areas of my house.

I needed to trace some circuits a my new house. This did the job easily.

A tool that everyone should own even if youre a DIY or professional, this tool saves so much time searching a circuit and keeps you safer doing so, cost is very low and is so easy to use, I highly recommend getting the accessories even if you think you dont need them, someday you may! I purchased everything including the separate Klein RT250 circuit tester and a carry case which holds all items securely. Buy it and you wont regret it

works as described . I only need it once but good to have in the tool box for future use .

I like it. It does what it says

No es tan exacto pero si ayuda mucho
