Why Choose the ABB EPH-66244-AM Protecta Home Consumer Unit?
The ABB EPH-66244-AM, manufacturer order code 1TVC151800S3080, is a 4+4-way dual RCD split-load consumer unit from the ABB Protecta Home series. Designed for residential electrical distribution, this consumer unit features a 63 A main switch isolator and two 63 A residual current circuit breakers (RCCBs), providing a practical solution for organising and protecting domestic electrical circuits.
As part of the ABB Protecta Home consumer unit range, the EPH-66244-AM combines incoming supply isolation with a dual RCCB arrangement for grouped residual current protection. Its 4+4-way split-load configuration allows outgoing circuits to be divided between two RCD-protected sections, supporting an organised electrical distribution layout and convenient circuit management.
With a 63 A main isolator, 2 × 63 A RCCBs and a dedicated 4+4-way configuration, the EPH-66244-AM is suitable for compatible residential distribution applications. Its AF-designated configuration identifies the unit within ABB's Protecta Home range for installations incorporating suitable circuit protection arrangements, including compatible arc fault detection devices where specified.

Reliable Electrical Distribution and Residual Current Protection
Consumer units form the central distribution point for electrical circuits within residential properties. They provide incoming supply isolation and accommodate protective devices that help safeguard electrical installations against electrical faults. Split-load consumer units divide outgoing circuits into separate groups, allowing residual current protection to be provided through more than one RCCB.
The ABB EPH-66244-AM Protecta Home consumer unit features a 63 A main isolator and two 63 A RCCBs arranged for a 4+4-way split-load configuration. The main isolator allows the incoming supply to the consumer unit to be disconnected, while the RCCBs monitor residual current imbalance and disconnect their associated circuits when the relevant trip conditions are reached.
The RCCBs provide residual current protection but do not independently provide overload or short-circuit protection. Each outgoing circuit therefore requires a correctly selected overcurrent protective device, such as a compatible MCB or an appropriate combined protective device. Where arc fault detection protection is required, suitable AFDDs must be selected and installed in accordance with ABB compatibility guidance and the electrical installation design.
The Protecta Home EPH-66244-AM provides a practical arrangement for residential electrical distribution where a dual RCD configuration is specified. Circuit allocation, protective device selection, enclosure installation and electrical testing should be carried out by a competent electrical professional in accordance with the applicable edition of BS 7671 and ABB installation instructions.
