Why Install Bidirectional RCBOs as Standard?
Boost Safety. Meet Compliance. Future-Proof Your Installs.
A bidirectional RCBO (Residual Current Breaker with Overcurrent protection) is more than just another component in your consumer unit. Unlike standard RCBOs, these upgraded devices can detect leakage currents flowing in either direction, which means better protection for your circuits, your customers, and your reputation.
At Live Electrical, we value information given to us from electricians and wholesalers across the UK. A common question we hear is: “Why do I need a bidirectional RCBO, aren’t standard ones enough?” This blog explains why the upgrade is not just recommended, but essential for today’s installs.
Why Choose Bidirectional RCBOs?
Let’s keep it simple: bidirectional RCBOs spot faults that regular RCBOs might miss. They help prevent electric shocks, fires, and other serious hazards, no matter which way the current flows.
The latest IET Wiring Regulations (BS 7671) increasingly consider systems like solar PV and battery storage. Using bidirectional RCBOs helps you meet modern safety standards, with peace of mind for both installer and customer.
Homes and businesses are changing. Solar panels. EV chargers. Battery storage. These all change the way current moves. A standard RCBO might not cut it, but a bidirectional RCBO can handle the complexity without compromising safety.
Nobody likes callbacks. With more accurate fault detection, bi-directional models reduce false trips, keeping lights on and customers happy.
Wiring matters. Whether you're using a double pole RCBO, RCBO consumer unit, or building out a custom RCBO board, follow the manufacturer’s diagrams carefully. If you’re unsure, start with our clear RCBO wiring diagrams or consult with one of our technical team members.
We also recommend reviewing official installation guidance from the IET to ensure compliance.
We’ve spent years designing and manufacturing electrical protection devices tailored for the UK market. Every product we release, including our bidirectional RCBOs, goes through rigorous testing to meet national safety standards.
Our gear is trusted by installers and stocked by wholesalers across the country. Whether it’s a consumer unit, an EV consumer unit or a three-phase distribution board, we build it to last, and we support it.
Looking for more than just RCBOs? We also supply:
Surge protection devices (SPD)
AFDDs (arc fault detection devices)
MCBs, enclosures, isolators, and accessories
Whether you're an installer looking for reliability, or a wholesaler wanting to stock what sells — now’s the time to make bidirectional RCBOs your new standard.
