RCDs detect differences in current between the live and neutral conductors, indicating a ground fault or leakage of current to unintended paths. How RCDs Work RCDs continuously monitor the current in the live and neutral conductors. If an imbalance is detected, such as current flowing
Read moreUnderstanding Surge Protectors Surge protectors, also known as surge suppressors, are devices designed to safeguard electrical equipment from voltage spikes or surges. Voltage surges can result from various sources, including lightning strikes, power grid fluctuations, and the switching of high-power electrical devices. How Surge Protectors Work Surge protectors contain components like metal oxide varistors (MOVs) that divert excess voltage to the ground when a surge occurs. They absorb the

Arc faults are caused by loose or damaged wiring and connections, and they can lead to electrical fires. AFCIs are crucial for preventing these fires by detecting the characteristic patterns of arcing and tripping the circuit. How AFCIs Work AFCIs continuously monitor the electrical waveform for telltale signs of arcing. When an arc fault is detect
Read moreUnderstanding GFCIs Ground Fault Circuit Interrupters (GFCIs) are electrical safety devices designed to prevent electric shock by quickly interrupting the flow of electricity when a ground fault is detected. Ground faults occur when current flows through an unintended path, such as a person or water, rather than the intended circuit. GFCIs are crucial in locations where water and electricity may interact, such as kitchens, bathrooms, and outdoor outlets. How GFCIs Work GFCIs monitor the flow
