Why Choose the ABB EPH-S10016 Protecta Home 16-Way 100A Main Switch Consumer Unit?
The ABB EPH-S10016 (ABB order code 1TVC151800S3031) is a 16-way, 100 A main switch consumer unit from ABB's Protecta Home range. Designed for low-voltage electrical distribution, this steel consumer unit combines a factory-fitted 100 A switch disconnector with a 16-way enclosure format, providing a practical foundation for suitable residential electrical installations.
Unlike an empty electrical enclosure, the EPH-S10016 is supplied as a main switch consumer unit assembly. ABB specifies that its Protecta Home steel consumer units come complete with a shrouded busbar, neutral bar, earth bar and installation instructions, together with the factory-fitted incoming switch or residual current device appropriate to the selected model. For the EPH-S10016, the specified incoming device is a 100 A main switch disconnector.
The unit measures 250 × 380 × 105 mm (H × W × D), according to ABB's published nominal dimensions. Its RAL 7035 grey steel enclosure provides a coordinated finish for suitable electrical service areas, utility rooms and other indoor installation locations.
With 16 outgoing ways, the ABB EPH-S10016 offers a useful balance between circuit capacity and enclosure size. It is particularly relevant for electricians specifying a 100 A main switch consumer unit where the required final-circuit protection will be provided by compatible devices selected for the completed installation.

100A Main Switch Isolation with 16-Way Distribution Capacity
The ABB EPH-S10016 is designed around a 100 A incoming switch disconnector, providing a means of isolating the consumer unit's incoming supply. This makes it suitable for installations where the electrical design calls for a main switch consumer unit with separately selected outgoing protective devices.
It is important to distinguish the 100 A main switch rating from the rating of the complete electrical installation. The incoming switch rating does not mean that every outgoing circuit can carry 100 A, nor does it override the requirements for supply capacity, protective device coordination, cable sizing or thermal performance.
The 16-way configuration provides a useful number of outgoing circuit positions for residential distribution. However, the number of devices that can actually be installed depends on their physical widths and ABB's approved assembly arrangements. Some RCBOs, MCBs and other modular devices may occupy different amounts of space, so the circuit schedule should be prepared before selecting equipment.
ABB's Protecta Home consumer unit specification includes a shrouded busbar, neutral bar and earth bar. These components support an organised internal wiring arrangement and provide the basis for correctly connecting the incoming supply and outgoing circuits, subject to the manufacturer's instructions.
The steel enclosure measures a nominal 250 mm high, 380 mm wide and 105 mm deep. These dimensions should be considered when assessing the mounting position, cable routes, accessibility and surrounding installation space. Adequate room must also be allowed for opening the enclosure and safely operating the incoming isolation device.
The EPH-S10016 is a main switch model, not one of ABB's factory-fitted RCCB or split-load variants. The incoming switch provides isolation but does not itself provide residual current protection. Where 30 mA RCD protection or other additional protection is required by the installation design and applicable regulations, suitable protective devices must be incorporated into the completed assembly.
ABB also offers alternative Protecta Home configurations, including 63 A main switch models, 100 A RCCB models and split-load consumer units. The correct variant should be selected according to the intended supply arrangement, number of circuits, protective device requirements and maintenance considerations.
Installation and commissioning should be completed by a competent electrical professional in accordance with ABB's instructions, BS 7671 and the requirements applicable to the completed distribution assembly. The installer must confirm device compatibility, earthing arrangements, circuit protection, enclosure suitability and the final electrical test results.
