Standard procedure to locate the problem is to try switching off some breakers to see where is the failure. Notice that your device is RCD residual current device (30mA) plus a 16A circuit breaker. It's basically a special kind of circuit breaker that can detect arcs/sparking/leakage between hot and ground/neutral that otherwise wouldn't be enough to trip a normal breaker by amperage alone. On it it has a rating of 200, does that mean Is my home at risk of a fire? No, not at all. What are the green, yellow, and red LED indicators on the Micrologic trip units of PowerPacT H, J, and L frame circuit breakers? Purpose of the green (ready), orange (>95) and red (>105) indicators on H, J and L breaker trip units Circuit Breaker When the green LED is flashing, the electronic trip. Every home relies on a breaker box (also called a service panel or distribution board) to manage and protect its electrical circuits.
