Why Choose the ABB EPH-S16216 Protecta Home 16-Way 100A Dual RCD Consumer Unit?
The ABB EPH-S16216 (1TVC151800S3068) is a 16-way, 100 A main switch consumer unit with two 63 A residual current circuit breakers (RCCBs), designed for residential and light commercial electrical distribution. Part of the ABB Protecta Home range, this split-load consumer unit combines centralised supply isolation, residual current protection and flexible outgoing circuit distribution within a robust steel enclosure.
Featuring a 100 A main switch-disconnector and 2 × 63 A RCCBs, the EPH-S16216 allows outgoing circuits to be arranged into two separately protected groups. Its variable split-load arrangement offers installation flexibility, enabling electricians to allocate circuits between the RCCBs according to the approved assembly configuration and the electrical installation design.
With 16 outgoing ways and manufacturer-listed nominal dimensions of 250 × 450 × 105 mm (H × W × D), the ABB EPH-S16216 provides additional circuit capacity compared with smaller Protecta Home split-load models. It is an effective choice for installations requiring multiple protected circuits, practical maintenance access and dependable ABB electrical distribution equipment.

Flexible Dual RCD Protection for 16-Way Split-Load Installations
The ABB EPH-S16216 combines a 100 A main switch with two 63 A RCCBs to provide incoming supply isolation and residual current protection for two groups of outgoing circuits. This split-load arrangement allows electricians to distribute circuits between separate RCCBs, rather than placing all circuits under one residual current protective device.
The variable split arrangement is an important feature of ABB Protecta Home RCCB split-load consumer units. It allows the distribution of outgoing ways between the two RCCB groups to be configured in accordance with ABB's approved assembly arrangements. With 16 outgoing ways, the EPH-S16216 offers additional flexibility for installations with multiple lighting, socket outlet and dedicated equipment circuits.
The 63 A rating of each RCCB is its rated current, not its residual operating current. RCCBs provide residual current protection but do not independently protect against overloads or short circuits. Appropriately selected outgoing overcurrent protective devices, suitable upstream protection and correct circuit allocation are therefore essential. Installation must comply with the applicable requirements of BS 7671 and the manufacturer's instructions.
Typical Applications
- Residential consumer unit installations in houses and apartments.
- New-build housing developments requiring multiple outgoing circuits.
- Domestic electrical distribution board replacements and upgrades.
- Property renovation and electrical refurbishment projects.
- Split-load electrical installations requiring two RCCB-protected circuit groups.
- Lighting, socket outlet and dedicated equipment circuits with suitable outgoing protection.
- Light commercial premises and small offices.
- Garages, workshops and ancillary building electrical distribution.
- Indoor electrical distribution systems requiring a 16-way consumer unit.
- Installations using compatible ABB modular circuit protection devices.
