Exempel på hur man kan använda RCDS i en mening

• Connecting exposed conductive parts to a "ground" wire which provides a low-impedance path for current to flow back to the incoming neutral (which is also connected to ground, close to the point of entry) will allow circuit breakers (or RCDs) to interrupt power supply in the event of a fault.
• RCDs are testable and resettable devices—a test button safely creates a small leakage condition, and another button resets the conductors after a fault condition has been cleared.
• Once widely used, more recent installations instead use residual-current devices (RCDs, RCCBs or GFCIs) which instead detect leakage current directly.
• In split-phase panels, separate busbars are fed directly from the incomer, which allows RCDs to be used to protect groups of circuits.
• They can be used to test residual-current devices (GFCIs) because the current drawn trips most RCDs when the solenoid voltmeter is connected between the live and earth conductors.
• Some units can also test RCDs, following the recommendation in the current IEE Code of Practice to test any RCD fitted on an extension lead or multiway adapter.
