RCD - Residual Current Device 
RCCB - Residual Current Circuit Breaker 
RCBO - Residual Current circuit Breakers integral Over current protection 
ELCB - Earth Leakage Circuit Breaker

RCD is the term that covers a family of devices.

RCCBs are RCDs without any overload protection.

RCBOs are RCDs with overcurrent protection included in the device.

CBRS are circuit breakers with residual current protection which may or may not be integral.

SRCDS are socket outlets with RCD protection.

PRCDS are RCDS built in to a plug.

MRCDS are independantly mounted devices that provide a signal to trip another device.

SRCBOS are sockets incorporating an RCD and overcurrent protection.

RCDs without overcurrent protection must be protected by a separate overcurrent device.

UPS

  • Online/double-conversion: the batteries are always connected to the inverter

  • Offline/standby: https://upload.wikimedia.org/wikipedia/commons/thumb/6/66/Standby_UPS_Diagram_SVG.svg/525px-Standby_UPS_Diagram_SVG.svg.png

  • Line-interactive: adjust if over/under normal voltage | https://upload.wikimedia.org/wikipedia/commons/thumb/2/24/Line-Interactive_UPS_Diagram_SVG.svg/750px-Line-Interactive_UPS_Diagram_SVG.svg.png
