12-Way Pre-Populated Consumer Unit — Type A RCD | UKCA Certified

12-Way Pre-Populated Consumer Unit — Type A RCD | UKCA Certified

The E1812TR-A is a 12-way pre-populated consumer unit supplied with Type A RCBOs factory-fitted, providing a complete, ready-to-wire consumer unit solution for modern domestic electrical installations. Every outgoing circuit is individually protected by a Type A RCBO — combining overcurrent, short-circuit and earth leakage protection (including pulsating DC fault detection) in each device. This eliminates nuisance tripping across unrelated circuits and provides the highest level of discrimination.

Type A RCBOs detect both AC sinusoidal and pulsating DC residual currents, meeting the requirements of BS 7671 (18th Edition) Amendment 2 for circuits supplying EV chargers, heat pumps, solar inverters and equipment with electronic converters. The pre-populated configuration saves significant installation time — the installer simply connects the incoming supply and outgoing circuit cables without needing to source and fit individual protective devices.

Key Features

• 12 usable ways — each protected by an individual Type A RCBO
• Type A RCBOs pre-fitted — detects AC sinusoidal and pulsating DC earth leakage faults
• Individual circuit protection — fault on one circuit does not affect any other circuit
• 100A main switch — provides safe local isolation of the entire installation
• Pre-populated and ready to wire — significant time savings on installation
• Meets BS 7671 Amendment 2 Type A requirements for EV, heat pump and inverter circuits
• Metal construction — powder-coated galvanised steel enclosure for fire resistance
• 35mm DIN rail — all devices factory-fitted and tested
• Neutral bar and earth bar included as standard
• UKCA certified — compliant with UK product safety regulations

Installation Notes

This consumer unit must be installed by a qualified electrician in accordance with BS 7671 (18th Edition). Always isolate the supply before installation. All RCBOs are factory-fitted — the installer connects the incoming supply tails to the main switch and routes outgoing circuit cables to the appropriate RCBO terminals. Each RCBO neutral must be connected to the device’s N terminal (not the main neutral bar) for the RCD element to function correctly. RCBO test buttons should be operated at least quarterly. Mount on a flat, non-combustible surface at a height between 450mm and 1350mm from finished floor level.
