If your RCD keeps tripping and you’ve narrowed it down to the socket circuit, follow this safe, step-by-step guide. This post is written for homeowners in Leeds and surrounding areas. If you’re unsure at any point, contact a qualified electrician in Leeds like Duravault Electrical.
Important Safety First
If you smell burning, see scorch marks, or hear buzzing from the consumer unit, do not attempt a reset. Call an emergency electrician in Leeds.
Never open the consumer unit cover beyond the user-accessible flap.
1) What You’ll Need
- A phone torch
- Notepad to track which appliances are unplugged
- Optional: plug-in socket tester (for basic checks)
- Step-by-Step: Resetting an RCD Caused by the Socket Circuit
2) Identify the tripped device
Locate your consumer unit (fuse board). You’ll typically see:
Main switch
One or two RCDs (test button “T”)
Several MCBs/RCBOs labeled (e.g., Sockets, Lights, Cooker)
- The RCD lever will be in the down/tripped position. Note which MCBs feed “Sockets” under that RCD.
- Turn off socket MCBs protected by the tripped RCD
- Switch all socket MCBs under that RCD to OFF.
- Leave lighting and other circuits off for now if they’re on the same RCD.
- Unplug everything on the affected socket circuit(s)
- Walk round and unplug all appliances: kettles, toasters, fridge/freezer, washing machine, dishwasher, TVs, chargers, outdoor equipment, garage sockets, garden tools, extensions.
- Check outbuildings, sheds, loft sockets, outdoor sockets, and Christmas lights—common culprits in Leeds homes due to damp ingress.
- Reset the RCD
- With all socket MCBs OFF and appliances unplugged, push the RCD firmly to ON.
- If it won’t reset, a fault may be on another circuit or the RCD itself—stop and call a qualified electrician in Leeds.
- Restore socket MCBs one by one
- Turn ON one socket MCB at a time.
- If the RCD stays on, move to the next MCB.
- When an MCB causes the RCD to trip immediately, you’ve found the problem circuit.
- Plug appliances back in, step by step
- On the problem circuit, keep the MCB ON and plug in one appliance at a time, switching it on.
- Wait 10–20 seconds between each. When the RCD trips, the last item plugged in is likely faulty.
3) Common triggers:
- Kettle/toaster (element faults)
- Fridge/freezer or washing machine (moisture/earth leakage)
- Outdoor sockets or pond pumps (water ingress)
- Damaged extension leads or surge protectors
- EV chargers or garden tools
- Isolate the faulty item
- Unplug the suspect appliance and reset the RCD.
- If the RCD now holds, keep that appliance unplugged and arrange repair/replacement.
If the RCD still trips with everything unplugged on that circuit, the issue could be:
- A damaged socket
- Water ingress in an outside socket
- Cable damage (e.g., drilled or rodent damage)
- Cumulative earth leakage from multiple appliances
- Faulty MCB/RCD
4) Test outdoor and garage sockets
- Inspect for moisture, cracked covers, or green discoloration. Do not use if damp is present.
- If weather-related, leave to dry and re-test later. Consider IP-rated replacements.
- Use a socket tester (optional)
Basic testers can flag missing earth or reversed polarity. If anything unusual shows, stop and book an electrician.
5) When to call an electrician
- RCD won’t reset with all MCBs OFF
- RCD trips with everything unplugged
- Burning smell, heat, buzzing, or signs of water ingress
- Repeated nuisance tripping (could indicate cumulative leakage or failing RCD)
- You’re unsure about circuit labeling or older fuse boxes
6) Preventing Future RCD Trips
- Replace damaged extensions and avoid daisy-chaining.
- Fit weatherproof, RCD-protected outdoor sockets.
- Keep appliances dry; avoid placing kettles/toasters under wall units where steam condenses.
- Schedule an Electrical Installation Condition Report (EICR) every 5 years (or when moving house).
- Consider RCBO upgrades for better fault separation in Leeds homes with many appliances.
