RCBOs for Consumer Units and Distribution Boards

RCBOs are used to provide circuit protection for individual circuits within consumer units and distribution boards. They combine overcurrent protection with residual current protection, helping protect against overloads, short circuits and earth leakage faults from a single device.

When selecting an RCBO, it is important to check the brand, board compatibility, breaking capacity, tripping curve, current rating, device type and terminal arrangement. RCBOs are not usually interchangeable between different consumer unit ranges, so compatibility should always be checked against the manufacturer’s instructions before installation.

Key Types of RCBOs

Single Pole RCBOs

Single pole RCBOs are commonly used for individual final circuits such as lighting, socket circuits and smaller domestic loads. They are often used in residential consumer units where each circuit requires separate residual current and overcurrent protection.

Double Pole RCBOs

Double pole RCBOs disconnect both live and neutral conductors. They are commonly used where full circuit isolation is required, subject to the installation design and manufacturer requirements.

Three Pole and Four Pole RCBOs

Three pole and four pole RCBOs are used for three-phase installations, including commercial and industrial systems where suitable residual current and overcurrent protection is required.

Bi-Directional RCBOs

Bi-directional RCBOs are designed for circuits where current may flow in either direction. They are often selected for modern installations involving equipment such as solar PV, battery storage or EV charging, where specified by the system design and manufacturer guidance.

Type A RCBOs

Type A RCBOs detect AC residual currents and pulsating DC residual currents. They are commonly used in modern installations with electronic equipment such as LED lighting, computers, appliances with electronic controls and EV-related equipment where required by the installation design.

Type AC RCBOs detect AC residual currents only. The correct RCD/RCBO type should always be selected in line with current wiring regulations, the connected equipment and the manufacturer’s instructions.

RCBO Tripping Curves

  • Type B curve – commonly used for domestic and light commercial circuits with lower inrush currents.
  • Type C curve – commonly used for circuits with higher inrush currents, such as certain lighting, motor or commercial loads.

Choosing the Right RCBO

Before ordering an RCBO, check the technical requirements of the installation and confirm compatibility with the consumer unit or distribution board. Important details include:

  • Brand and board compatibility
  • Current rating, such as 6A, 16A, 20A, 32A, 40A or 50A
  • Breaking capacity, such as 6kA or 10kA
  • Tripping curve, usually Type B or Type C
  • RCD type, such as Type A
  • Single pole, double pole or three-phase format
  • Terminal position and busbar compatibility

RCBO FAQs

What does an RCBO do?

An RCBO combines residual current protection and overcurrent protection in one device. It helps protect a circuit against earth leakage faults, overloads and short circuits.

Can I fit any RCBO into any consumer unit?

No. RCBOs should be compatible with the specific consumer unit or distribution board range. Always check the manufacturer’s compatibility information before installation.

What is the difference between Type B and Type C RCBOs?

Type B and Type C refer to the tripping curve. Type B RCBOs are commonly used for circuits with lower inrush currents, while Type C RCBOs are used where higher inrush currents may be expected.

What is a Type A RCBO?

A Type A RCBO detects AC residual current and pulsating DC residual current. It is commonly specified for many modern circuits with electronic equipment.

Who should install an RCBO?

RCBOs should be selected and installed by a qualified electrician who can confirm the correct rating, type, compatibility and installation requirements.
