Circuit Breaker Finder Kit with GFCI Outlet Tester for 90-135V AC Circuits,includes Light Socket Adapter, 3-2 Prong Grounding Adapter & Clip adapter,Portable Electrical Tool with Carrying Case

Q1: Is professional electrical experience required to operate this tool?

A: With its one-button operation and clear visual and audible indicators, even DIYers can safely trace breakers within minutes. We provide a step-by-step illustrated guide.

Q2: Why does our circuit detector need to install batteries in the transmitter?

A： Our battery powered transmitter offers three key advantages that set us apart:

1.Safety compliance: LCD screens will increase energy consumption, exceeding the 3mA limit for direct AC operation under the EN 61243-3:2010 international safety standard. The battery power ensures full compliance with requirements while maintaining professional grade accuracy.

2.Power outage data protection: When the circuit trips, our transmitter will save the measurement data for 10 seconds, which is crucial for recording fault details. Non battery designs will immediately lose all data after a power outage.

3.GFCI Performance Indicators: Our device's unique battery can perform post trip analysis by displaying the precise GFCI trip duration (0.1s resolution) even during power outages, which is a necessary feature for electricians to verify the responsiveness of the protection system.

Q3：Why is the transmitter's battery cover secured with screws instead of a tool-free design?

A： Spiral sealed battery compartment is a deliberate safety innovation designed to meet the requirements of IEC61010-1 for electrical enclosures in high-voltage environments, in order to prevent non professionals from opening it at will, avoid the risk of electric shock or short circuit.
