Abstract: An arc-like radio frequency (RF) noise detector device is configured to detect and display RF noise on a residential circuit branch that cause or contribute to an arc fault circuit interrupter (AFCI) circuit breaker tripping. It includes a power cord with a plug to connect to a receptacle on a branch circuit of the AFCI circuit breaker to detect RF noise. It further includes a RF noise coupling circuit to receive power from a power entry module and coupled to an Application Specific Integrated Circuit (ASIC) to generate a Received Signal Strength Indicator (RSSI) signal from the detected RF noise. It further includes a power supply, a signal display device configured to receive and display the RSSI signal on a display screen to determine nature of a breaker trip event or likelihood of the breaker trip event and a battery to power the signal display device.
