How to Fit an RCD

An RCD, or residual current device, is most commonly known in North America as a ground fault circuit interrupter (GFCI) outlet. These devices monitor the wires for imbalances in the electrical load due to leakage. When detected, the device shuts off the power, reducing the likelihood of electrocution. In modern residential buildings, they are required for kitchen, bathroom and exterior outlets. Upgrading your electrical outlets to RCDs is a simple, inexpensive job.
