It is also recommended to install residual-current devices for protection against electrocution.

Similar devices that are current operated are called residual-current devices.

The diagram depicts the internal mechanism of a residual-current device (RCD).

Residual-current devices (RCD)s protect against earth leakage using a different method of detection.

Installing a residual-current device (GFCI) on the outlet may reduce the shock risk.

These versions of the 5-15 or 5-20 receptacle are residual-current devices and have Test and Reset buttons (and sometimes an indicator light).

Residual-current device, also sometimes called Residual Current Breaker (RCB)

(Outside North America these are referred to as a "Residual-current device" or RCD.)

Nowadays, ELCBs have been mostly replaced by residual-current devices (RCDs).

Residual-current device is a generic term covering both RCCBs and RCBOs.

Modern installations may use residual-current devices (RCDs) or residual current breakers with overcurrent protection (RCBOs).

In the United Kingdom, a residual-current device is referred to as a RCD or a RCBO when including overcurrent protection.

In TN-S and TT systems (and in TN-C-S beyond the point of the split), a residual-current device can be used as an additional protection.

An earth leakage circuit breaker (ELCB) may be a residual-current device, although an older type of voltage-operated earth leakage circuit breaker exists.

This makes them useful for testing residual-current devices (GFCIs) because the current drawn will trip most RCDs when the solenoid voltmeter is connected between the live and earth conductors.

Some units can test Residual-current devices, following the recommendation in the current IEE Code of Practice to test any RCD fitted on an extension lead or multiway adapter.

A high impedance line-to-ground fault insufficient to trip the overcurrent protection may still trip a residual-current device (ground fault circuit interrupter or GFCI in North America) if one is present.

Eaton Electric (former Delta and MEM) make residual-current devices (Cutler-Hammer) and switchgear off the A41 in Tyseley, and Mereway Kitchens is nearby.

Normally, a main switch, and in recent boards, one or more Residual-current devices (RCD) or Residual Current Breakers with Overcurrent protection (RCBO), will also be incorporated.

Apart from the products you might expect to be counterfeited - T-shirts, sunglasses, and watches - there are also a lot of unexpected things being copied, such as automotive accessories, bearings, residual-current devices, pencils, glue, and food products.

The provision of a Residual-current device (RCD) or ELCB to ensure safe disconnection makes these installations EEBAD (Earthed Equipotential Bonding and Automatic Disconnection).

Residual-current devices, also known as ground-fault circuit interrupters and appliance leakage current interrupters, are used to detect ground faults - leakage of current to somewhere other than the neutral and live wires (like the ground wire or a person).

Residual-current device Domestic AC power plugs and socketss can reduce the risk of electric shock, and are required for bathroom socket installation by National Electrical Code (US) and building codes in the United States and Canada.

Some extension cords also incorporate safety features, such as a polarized plug and receptacle, grounded terminals, a 'power-on' indicator, a fusible link, or even a residual-current device (also known as a ground-fault circuit interrupter or GFCI).

A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor.
