As the projects are very expensive, salaries are usually higher in utility scale than residential solar. It is likely that the cost of RCDs and the potential for nuisance tripping has led to some organisations exploiting the loophole and omitting the protective devices under the pretence that the socket outlets were sufficiently supervised to pose no risk. A non-latching safety RCD plug adaptor is designed to provide an additional layer of protection. These types of RCDs protect the circuit from overload, as well as earth leakage faults; therefore called an RCBO. Unfortunately, many business owners do not realize the harm that electricity poses. It also provides some protection against electric fires. A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground.It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock.
