- HPM RCD Safety Switch constantly monitors the balance of the current flow in both active and neutral wires of the device and down stream lead.
- If an imbalance occurs, as it would if the appliance became faulty and current leaked to earth (possibly through the body of the user), the RCD Safety Switch would detect this imbalance and cut off the power within 40ms
- The loss of current to earth can be as small as 30 milliamps (thirty thousandths of an amp) for the RCD Safety Switch to respond. The time that a person is exposed to an electric shock is a crucial factor in determining the severity of the accident.
