An Earth Leakage Circuit Breaker (ELCB) (now referred to as residual current circuit breaker) is a safety device used in electrical installations with high earth impedance to prevent shock. History ELCBs were mainly used on TT earthing systems. Nowadays‚ ELCBs have been mostly replaced by residual-current devices (RCDs). However many ELCBs are still in use. Early ELCBs responded to sine wave fault currents‚ but not to rectified fault current. Over time‚ filtering against nuisance trips has also

Our home heating costs were high because of poor insulation‚ drafty windows‚ and an inefficient furnace. Homes using passive solar energy have lower heating bills than others. Higher heating costs have made architects design more energy-efficient homes. Lowering home heating costs is easy if one follows
