DIY Tool for ELCB Trip Test (Circuit Breaker Finder)

How to find out which of several circuit breakers supplies power to a specific load.
I made a tester using a 6.8k ohm resistor and switch, a neon lamp for this.
It can generate a leakage current of 30mA at AC 220V.
When applied to 120V GFCI, leakage current is 15mA.
Materials :
Plastic Bottle
6.8k ohm 2W Resistor
150k ohm 1/4W Resistor
Neon Lamp
Push Switch(Normally Open)
Alligator Clips

This work on regular breaker hello .

The 1/4w resistance is 150kOhm or 15kOhm? I ask it because in the first case, according to Ohm law, results 220 V / (156kOhm) ~ 1.5mA, not 10mA. Thanks for sharing!

150k is for lamp only.
