Installing a Residual Current Protection Distribution Box

Home / Installing a Residual Current Protection Distribution Box

Installing a residual current device (RCD) in your ABB distribution board is relatively simple if you're a bit tech-savvy. A Residual Current Breaker with Overcurrent Protection (RCBO) is a protective device that safeguards electric circuits and appliances from both short circuits/overcurrents and leakage/earth faults. It incorporates features of both Miniature Circuit Breakers (MCBs) and Residual Current Devices (RCDs. Therefore, an RCD exposed to such waveforms needs to be of a suitable type, otherwise a distorted. Always follow a step-by-step approach, use the appropriate tools, and understand the wiring plan thoroughly.

RCD Handbook 2018

Residual current devices with a tripping current of 30 mA or less are now widely used in all types of electrical installation and provide valuable additional protection against the risk of electrocution.
