What should be used for an effective personal safety measure with temporary wiring?

Using GFCI (Ground Fault Circuit Interrupter) protection is crucial for effective personal safety measures with temporary wiring, especially in environments where moisture is present, such as construction sites or outdoor settings. GFCI devices are designed to detect ground faults, which occur when there is an unintended path between the electrical source and the ground. If a fault is detected, the GFCI swiftly cuts off power, reducing the risk of electric shock. This feature is particularly important for temporary wiring, which may not be installed to the same permanent standards.

While circuit breakers and fuses provide overcurrent protection, they do not specifically protect against shocks caused by ground faults. Excess wiring can lead to hazards such as trip hazards or unintentional disconnection, but it does not contribute to safety in the way that GFCI does. The use of GFCI ensures a more robust safety protocol in any temporary electrical setup.
