\ud83c\udfaf No more round trips in front of the electrical panel !!<\/h2>\n

I will be honest, since I have the Kaiweets KTL01<\/strong><\/a>, I feel much more serene before touching an electrical circuit.<\/p>\n

But there is still a small galley that I meet regularly: I know how to cut a circuit breaker, I know how to check that a socket is off, but I do not always know which circuit breaker powers the socket on which I want to intervene<\/strong>.<\/p>\n

Result: I go down to the board, I cut a circuit breaker, I go up, I test the plug, I go down again, I try the next one... And sometimes I cut several circuits outright to be quiet.<\/p>\n

It is exactly for this kind of situation that I wanted to test the Kaiweets KT301E<\/a><\/strong>, a digital circuit breaker locator.<\/p>\n

The idea is simple: a transmitter is plugged into the socket to be identified, then a receiver is passed in front of the circuit breakers in the switchboard. When the correct circuit is found, the device shall clearly indicate it.<\/p>\n

Here is my feedback after several uses in concrete situations.<\/p>\n

\u26a1 Why this locator in my home automation toolbox<\/h2>\n

I install a lot of home automation equipment: Zigbee sockets, modules behind switches, sensors, power supplies, sirens, various boxes.<\/p>\n

And before each installation, there is often an electrical step.<\/p>\n

The problem is not just cutting power. That is to know: which circuit to cut<\/strong>.<\/p>\n

With my KTL01<\/strong><\/a>, I check the presence of tension. With the KT301E<\/a>, I want to identify the circuit breaker concerned without going back and forth between the part and the board.<\/p>\n

The KT301E<\/a> is designed to quickly identify the circuit breaker connected to an outlet or point of use, by means of a transmitter connected to the outlet and a receiver passed in front of the switchboard.<\/p>\n

But it is not limited to this function: the transmitter also serves as a socket tester and makes it possible to control the condition of the wiring, the presence of mains voltage and protection by circuit breaker.<\/p>\n

\"\"<\/div>\n

For a DIY do-it-yourselfer, it is a tool that complements the KTL01 well: one alerts on the presence of voltage, the other helps to find the right circuit breaker.<\/p>\n

\ud83c\udfe2 Who is Kaiweets?<\/h2>\n

\"\"<\/p>\n

Kaiweets is a Chinese brand specialising in electrical measuring devices and tools for both professionals and private individuals.<\/p>\n

I had already tested their KTL01<\/strong><\/a>, a contactless voltage tester that convinced me of its simplicity and pen format. The KT301E<\/a> belongs to the same logic: an accessible tool, designed for everyday interventions.<\/p>\n

Here, we are no longer talking only about detecting a voltage, but about find the circuit that feeds an outlet<\/strong>.<\/p>\n

\ud83d\udd0d Why I chose the KT301E among the Kaiweets models<\/h2>\n

Kaiweets offers several circuit breaker locators, with more or less advanced functions. Here are the models I have identified:<\/p>\n\n\n\n\n\n\n\n
