Why Choose the ABB EPH-H.I Protecta Home High Integrity Add-On Kit?
The ABB EPH-H.I is a practical high integrity add-on kit designed for use with compatible ABB Protecta Home consumer units. This accessory provides a dedicated high integrity neutral arrangement for two MCB or RCBO circuit positions, allowing electrical installers to configure selected outgoing circuits separately from the shared RCCB-protected groups of a suitable split-load consumer unit.
As part of the established ABB Protecta Home electrical distribution range, the EPH-H.I enables greater flexibility when designing domestic electrical installations. High integrity circuit arrangements are particularly useful where selected circuits require individual residual current protection through RCBOs rather than relying on a shared RCCB. This approach can help minimise the effect of a residual current fault on other circuits when the installation is correctly configured.
The ABB EPH-H.I High Integrity Add-On Kit, manufacturer order code 1TVC151800S3291, is specifically identified by ABB as a High Integrity Neutral x2 MCB/RCBO accessory. It provides an installation solution for incorporating two suitable MCB or RCBO positions into compatible Protecta Home distribution arrangements, supporting flexible circuit organisation and professional consumer unit configuration.

Reliable High Integrity Circuit Configuration for Domestic Electrical Distribution
High integrity arrangements are used in electrical distribution boards to provide dedicated circuit positions that can be configured independently of shared RCCB-protected groups. In a conventional split-load consumer unit, several outgoing circuits may be protected by the same RCCB. If a residual current fault occurs on one circuit, the shared RCCB can disconnect all circuits connected to that protected group.
The ABB EPH-H.I High Integrity Add-On Kit supports an alternative arrangement by providing a high integrity neutral configuration for two MCB or RCBO positions. When suitable RCBOs are installed, individual circuits can receive their own residual current and overcurrent protection. This can help limit the effects of an electrical fault to the affected circuit rather than disconnecting an entire shared RCCB group.
The dedicated neutral arrangement is an important part of correct high integrity circuit configuration. Neutral conductors must be connected to the appropriate terminals according to the consumer unit wiring arrangement and the requirements of the installed protective devices. Incorrect neutral connections can interfere with residual current protection and cause unwanted tripping or unsafe operating conditions.
The EPH-H.I is a consumer unit configuration accessory rather than a standalone protective device. It does not independently provide overload, short-circuit or residual current protection. Suitable MCBs, RCBOs and other protective components must be selected separately according to the electrical installation design.
As part of the ABB Protecta Home accessory range, the EPH-H.I offers electrical installers a practical method of adapting compatible consumer units for high integrity circuit arrangements. Installation should follow ABB's applicable assembly instructions and the requirements of BS 7671, with compatibility and available circuit positions checked before fitting.

Frequently Asked Questions
What is the ABB EPH-H.I used for?
The ABB EPH-H.I is a high integrity add-on kit used with compatible ABB Protecta Home consumer units. It provides a dedicated high integrity neutral arrangement for two MCB or RCBO positions, allowing selected circuits to be configured separately from shared RCCB-protected groups.
What does high integrity mean in a consumer unit?
A high integrity arrangement provides dedicated circuit positions that can be configured independently of shared RCCB groups. When suitable RCBOs are installed, individual circuits can receive their own residual current protection, helping reduce the possibility of unrelated circuits being disconnected by a fault on another circuit.
How many circuit positions does the ABB EPH-H.I support?
ABB identifies the EPH-H.I as a High Integrity Neutral x2 MCB/RCBO accessory, providing a high integrity neutral arrangement for two suitable MCB or RCBO circuit positions.
Is the ABB EPH-H.I compatible with Protecta Home consumer units?
Yes. The EPH-H.I is part of the ABB Protecta Home accessory range and is designed for compatible consumer unit arrangements. The specific consumer unit configuration, available space and manufacturer installation requirements should be checked before fitting.
Does the ABB EPH-H.I include an MCB or RCBO?
The EPH-H.I is identified as a high integrity neutral add-on kit, not as an MCB or RCBO protective device. Suitable circuit protective devices must be selected separately according to the installation requirements.
What is the difference between an MCB and an RCBO?
An MCB provides protection against overloads and short circuits, while an RCBO combines overcurrent protection with residual current protection in a single device. The ABB EPH-H.I supports high integrity circuit arrangements using suitable MCBs or RCBOs.
Can the ABB EPH-H.I help reduce unwanted circuit disconnection?
Yes. When used as part of a correctly designed high integrity arrangement with suitable RCBOs, the EPH-H.I can help separate selected circuits from shared RCCB groups. This allows a residual current fault on an individually protected circuit to be disconnected without necessarily interrupting other circuits.
Does the ABB EPH-H.I provide electrical protection by itself?
No. The ABB EPH-H.I is a consumer unit accessory that supports high integrity circuit configuration. It does not independently provide residual current, overload or short-circuit protection. Appropriate protective devices must be installed separately.
What is the ABB order code for the EPH-H.I High Integrity Add-On Kit?
The ABB manufacturer order code is 1TVC151800S3291, and the product model designation is EPH-H.I.
Who should install the ABB EPH-H.I?
The EPH-H.I should be installed by a competent electrician familiar with consumer unit assembly, protective device coordination and neutral conductor arrangements. Installation must follow the applicable ABB instructions and electrical installation requirements.
