Customer Review

Reviewed in the United States on February 2, 2020
They kind of don’t say a whole lot about what thing does so I scoped it out of curiosity. It seems to create a lot of high frequency amperage spikes which is seen as voltage variation on the line which the Afcis breaker looks for. I included a waveform picture which shows generally what’s going on. It inserts that on top of every other sine wave cycle. I did also capture at very high frequency and looked at it in detail. The frequency shape is very similar to an arc i captured off starting my air compressor where you get an arc with voltage drop then the voltage kind of rings down. This device makes a whole mess of those. The only real difference I saw between an actual arc and this is the frequency. I would say the frequency from an actual arc was 5-10x faster. Still tripped my afci’s so whatever that could just be a function of the arc i compared it against and not always the case. I would also say in doing this on a non AFCI circuit to be able to capture the waveform those big green resistors got toasty pretty quick and the device thermally protects itself. Neat stuff.
