I put the Klein ET310 to the test on a received electrical venire by attempting to cope with more than a dozen different circuit . I started with circuits close to the electrical panel before expanding outward to sales outlet in the further reaches of my business firm .
I also tested the ET310 ’s extra features , including its ability to distinguish faulty wiring and essay GFCI outlets . The ET310 also underwent a ruggedness test , during which I repeatedly dropped it on a concrete garage floor from waist peak .
Not only did the Klein ET310 reliably match circuit breakers with their corresponding outlets , but it was also gentle to habituate and offered more function than other similarly priced circuit - ledgeman finders .

What is the Klein ET310 circuit-breaker finder?
The ET310 circuit - breakers finder aid homeowner match outlets , light socket , and bare wires throughout their home to the like electric circuit breakers on their electrical control board . In guild to test bare wires and socket , however , the user will demand anoptional accessory kit .
The peter work likewise to other electrical circuit - breaker finders . It comes with a transmitter that plugs into a standard three - prong outlet and get off a sign to the electric instrument panel . When the receiver is deem over the matching breaker on the electrical dialog box , it emits a flavour and crystallize an light-emitting diode light .
In addition to its ability to equalise sockets with circuit breakers , the ET310 also function as a GFCI tester and incorrect - wiring detector . Pushing a button on the sender creates a brief surge in the line that trips the outlet ’s build - in fuse , letting the user know if it ’s working right .

The sender also operate as a incorrect - wiring index number that identifies reversed wiring , missed primer coat , and capable hots ( live wire that do not connect to the mogul author ) via a three - precede light codification . While there are many circuit - breakers finders capable of those job , what makes the Klein stand out is its user - well-disposed intent and power to match outlets and circle breakers with a high degree of truth .
Is the Klein ET310 easy to set up?
Setting up theKlein ET310is fairly easy . The transmitter plug into any standard three - prong 120 - volt electric receptacle . From there , the transmitter sends a signal to the electric control board through the home ’s wiring .
Since the ET310 use an automatic pass receiver , I first had to span the receiver over each breaker on the panel so it could “ learn ” the electrical control panel . As I performed the sweep , the pass receiver mechanically adjusted its sensitivity to eliminate false positives . A 2nd scan of the venire revealed the matching breaker .
While the machine sensitivity feature makes the ET310 well-off to utilize , having to complete this prescan before matching each circle surf can be deadening , especially when matching a lot of outlet and breakers . Those who are used to using a circuit - breaker finder may prefer a model that get them adjust the sensibility manually .

The receiver have me know I was getting confining by beeping more quickly as I approach it . This “ you ’re sire hotter ” design made it easier to prevail out erroneous breakers and ultimately zero in on the correct one during my tests .
The curved ergonomic shape of the pass receiver ’s read/write head also made it easier to perform scans . Many circuit - surf finders have a true head , which makes it more hard to hold the receiver in position while scanning along the board . The angled top dog on the ET310 makes it sluttish to get good contact with each breaker . Klein also sagely puts an LED indicator light on the back of the forefront , making it easy to read from behind the receiver .
The receiving system ’s grip fits nicely in hand with the power / reset clitoris powerful under the thumb , making it easy to turn the receiver off , on , or readjust it . However , users will desire to take note that this location makes it rather soft to switch on unexpectedly .
The Klein ’s other functions are also intuitive and easy to use . The transmitter has a large button for quickly test GFCI circuit , a function that worked faithfully during my examination . I liked that it displayed the position of the outlet ’s wiring via its three LED light as soon as I plugged it in .
There ’s also a three - prong outlet on the back of the pass receiver that I could connect to the transmitter when I was n’t using it , which is a great lineament for those who are fain to misplace thing .
How well does the Klein ET310 work?
A circuit - breaker finder is only as upright as its power to match breaker accurately to their corresponding outlets . In that capacity , theKlein ET310excels . I conducted more than a 12 different tests using outlets tight to the electric dialog box and those in the far reaches of my base .
For each test , I cover the description on the electrical box seat doorway to ensure I was guided only by the receiver ’s beeps and lead indicator ( and not the label on the dialog box ) . The Klein ET310 was consistent with each vent I screen . It begins beeping more chop-chop within a tour breakers or two of the match . When it hits the matching breaker , the green LED light turns red , and the beep variety to a single tone .
During my tests , it had no problem get off my GFCI circuits , confirming that they were operating correctly . While I could not test the transmitter on faulty wiring , the Klein confirmed that the wiring in the outlet I tested was intelligent .
How durable is the Klein ET310?
circle - breaker finders , like most dick , will be open to some level of abuse . Any secure dick should be able-bodied to withstand being knocked around in a puppet box or occasionally put down on a arduous flooring .
I tested the ET310 ’s lastingness by repeatedly dropping it from waistline tallness onto my hard concrete garage floor . While it have a few enhancive mark , it emerged largely unscathed , which is a testament to its solid construction . Based on the sturdy overall feel of the receiver and transmitter , I conceive it would have to fall from much greater height to stand catastrophic scathe .
Is the Klein ET310 worth the money?
lap - surf finders for homeowners follow in a fairly wide monetary value range from as little as $ 30 to more than $ 100 . While theKlein ET310isn’t the chintzy circuit - circuit breaker discoverer on the marketplace , it is among the most low-cost . It ’s also gentle to use and accurately match breaker to their match vent . Plus , it admit additional social occasion for test GFCI circuit and identify wrong wiring , which is something not found on most circuit - breaker finders at this price point .

The Klein ET310 is an excellent tool for those who want to take the guesswork out of matching circuit surf to outlets . The ET310 is precise and take very slight expertness to use ably . I also loved that the ET310 allowed me to do other map while matching circuit breakers , including test GFCI outlets and describe potentially grievous wiring issues .
Despite these pros , the ET310 does have its limitations . While most DIYers will appreciate its auto predisposition , those with more experience may opt a circuit - breaker discoverer that allow them to adjust the sensitivity manually . The ET310 also only tests circuits up to 120 volts . While this covers the majority of outlets , lights , sockets , and other electrical connections in one ’s household , it wo n’t work with the 220 - volt outlets that ovens , dryers , and air - conditioning units utilize . Those who call for to test gamy - voltage wiring will need to upgrade to a pro - level circumference - circuit breaker discoverer .
