EKDB16S(L)-I2R Dual RCD configuration offers enhanced supply continuity by balancing circuits across two independent 80A RCDs. This "high integrity" setup, fed by a 100A main switch, ensures that a fault on one RCD-protected bank of circuits does not affect the other, keeping essential services running. It's the standard for modern domestic installations, providing a robust and reliable distribution solution. The BS EN 61439-3 compliant steel enclosure includes top-mounted terminals and a removable DIN rail for a structured, professional installation. Select "SL" models for an integrated door lock.
Q1: How should I balance the circuits?
A1: It is best practice to split lighting and socket circuits across both RCDs. For example, put upstairs lighting and downstairs sockets on RCD 1, and downstairs lighting and upstairs sockets on RCD 2.
Q2: Are there any ways directly on the main switch?
A2: In this standard dual RCD configuration, all outgoing ways are protected by one of the two RCDs.
Q3: What are the RCD ratings?
A3: The board includes two double-pole 80A, 30mA Type A RCDs.
Q4: How many ways are protected by each RCD?
A4: On the 18-way model, each RCD protects a busbar with 7 ways, offering a total of 12 free ways after the main switch and RCDs are fitted.
Q5: Is a lockable version available?
A5: Yes, select the "SL" variant for an integrated door lock.
