Residual current circuit breakers (RC circuit breakers) are important components for protection from electrical accidents, especially grounding through the body. Since 1984, RC circuit breakers are required for bathrooms in newly constructed buildings. When old buildings are renovated, they must also be retrofitted with RC circuit breakers. Since 2009, it has been mandatory to equip all outlet circuits with a 30 mA ground-fault protection. This is enough reason for us to ensure the highest quality in the selection we have made for this category.
