    BG Dual RCD metal DB's

    Anyone had issues with the RCD's? Added a spur from a new DB yesterday (not installed by me). The RCD failed the 5x test when tested at the load terminals with all mcb's off. Perplexed I tried the other RCD with the same result. MFT tested the RCD on another job later with results as expected.
