Tripping RCDs in older terraced homes
Why it happens here
Many St Edmund's terraces have wiring that's been added to over the years, often with poor connections or damaged insulation. When moisture gets in or a circuit is overloaded, the RCD trips to prevent a fire.
Our approach
We use insulation resistance testers to find the exact fault, rather than just resetting the RCD. We repair or replace the damaged section and test the whole circuit to ensure it's safe.
