What we still see in Deal fuseboards.
Deal's older housing stock throws up the same fuseboards year after year. Wylex plug-in fuse units from the 1960s and 70s, still going in 1930s ex-council semis in Mill Hill. Wylex Standard board with rewireable fuses. Early split-load boards from the 1990s with a single 30mA RCD and a bank of MCBs. Plastic-enclosure boards from the 2000s and 2010s that met the 17th Edition when they were installed but no longer meet Amendment 2's metal-enclosure requirement introduced 2016 and reinforced in 2022.
The red flags.
- Burn marks or discolouration around a fuse or MCB. Loose termination, arcing, or overload. Immediate.
- The RCD trips randomly, often at night. Cumulative earth leakage from a marginal circuit tips the single 30mA RCD. Common on the seafront where salt-air degradation raises leakage.
- Rewireable fuse wire, not MCBs. No shock protection, no calibrated trip curve. Replace.
- Plug-in Wylex fuses. Even the cartridge versions - no RCD protection, no SPD, no metal enclosure. Replace.
- No RCD at all on socket circuits. Non-compliant even under 17th Edition. Priority replace.
- Hot to the touch. Board or supply-tail termination is loose or over-loaded. Investigate immediately.
- Buzzing or humming from the board. Contactor, loose neutral, or failing MCB. Investigate.
- Fuse wire has been "up-rated" - 15A wire in a 5A holder because it kept blowing. Circuit is now unprotected against overload. Serious risk.
What Amendment 2 requires now.
18th Edition Amendment 2:2022 tightened several things on new consumer unit installations in domestic property:
- Metal enclosure (introduced 2016, retained).
- SPD (surge protection device) - now required in most domestic installations unless a specific risk assessment justifies omission.
- AFDD (arc-fault detection device) - recommended on final circuits feeding sleeping areas and other higher-risk locations in AC-supplied dwellings above certain thresholds.
- All final circuits RCD-protected (30mA), either via dual-RCD split-load or full-RCBO board.
What a replacement looks like.
Straightforward Deal domestic swap: 6-10 way metal-enclosed board, dual-RCD or full-RCBO, SPD integrated, existing tails re-terminated to a new main switch. Meter position and DNO fuse rating checked. Main earth conductor verified to 25mm² (or upgraded). Supplementary bonding checked in bathrooms. Full initial verification. Electrical Installation Certificate issued on the day.
Typical timeline: single day, power off between 09:00 and 16:00, temporary supply for fridge and Wi-Fi.
