RCDs or RCBOs, do you have the right protection?
The way electrical installations are designed and the electrical equipment we have at our disposal has come a long way in recent years. Today's consumer units are far safer than the fuse boxes of the past, part of this increased protection is due to something called a Residual Current Device (RCD). These devices detect when a fault is occurring and shut off power to the circuit, reducing the risk of fires and electrocution.
