Faulty insulated equipments or wrong useage of electrical devices cause current to flow through insulation to the earth. This is leakage current. This current poses two severe risk factors which are:
- Fire Risk
- Electrocution Risk
Residual Current Circuit Breaker provides the function of isolation switching and earth leakage protection of electrical circuits. It also provides the indirect protection of the operator’s body against the dangerous effects of electric current. It is also a protective device against fire caused by the electrical circuit fault.
