= Heating Fault Decision Tree =

== Purpose ==
To quickly identify whether a heating fault is caused by controls, wiring, or the boiler itself.

---

== Step 1: Identify Symptom ==
* No heating at all
* No hot water
* Intermittent heating
* Heating stuck ON
* Boiler not firing

---

== Step 2: Check Demand Exists ==
* Raise room thermostat above ambient temperature
* Check programmer is calling for heating/hot water
* Observe:
** Valve movement
** Relay clicks
** Boiler attempt to fire

IF NO DEMAND:
→ Control issue (thermostat/programmer/wiring)

IF DEMAND PRESENT:
→ Move to Step 3

---

== Step 3: Check Zone Operation ==
* 2-port valve opens? (S-Plan)
* 3-port valve moves correctly? (Y-Plan)
* End switch activates?

IF NO MOVEMENT:
→ Valve or actuator fault

IF MOVEMENT BUT NO BOILER FIRE:
→ Electrical interlock fault

---

== Step 4: Check Boiler Signal ==
* Verify switched live present at boiler terminal
* Check boiler enable input
* Confirm no internal lockout

IF NO SIGNAL:
→ Wiring/control issue upstream

IF SIGNAL PRESENT:
→ Boiler fault likely

---

== Step 5: Final Isolation ==
* If controls and wiring are correct:
→ Treat as boiler-side issue
* If signal missing or incorrect:
→ Control system fault confirmed

New page

= RCD Fault Finding Checklist =

== Purpose ==
To provide a structured, practical method for identifying why an RCD is tripping and locating the fault safely and efficiently.

== Common Reasons An RCD Trips ==

* Earth leakage on a circuit (most common cause)
* Faulty appliance plugged into a socket circuit
* Damaged cable (nails, screws, heat, crushing)
* Moisture ingress into accessories or outdoor equipment
* Neutral-to-earth fault anywhere on the protected side
* Incorrect neutral connection (borrowed neutral / mixed neutrals)
* Faulty RCD device
* Overcrowded or poorly maintained wiring causing leakage
* External equipment faults (garden lighting, outbuildings, showers, pumps)

---

== Step-by-Step Fault Finding Procedure ==

=== 1. Confirm The Fault ===
* Check what exactly is tripping:
* RCD main switch
* Individual RCBO
* Note if it trips instantly or after a delay.
* Try to identify when it started (recent work, weather change, new appliance).

---

=== 2. Initial Isolation ===
* Switch OFF all MCBs/RCBOs on the affected RCD.
* Reset the RCD.
* If it holds, the fault is downstream on a circuit.
* If it still trips with everything off, suspect:
* Faulty RCD
* Neutral issue in the board

---

=== 3. Re-Energise One Circuit At A Time ===
* Turn circuits back on one by one.
* Wait after each circuit is energised.
* Identify which circuit causes the RCD to trip.

---

=== 4. Isolate The Problem Circuit ===
* Leave the faulty circuit OFF.
* Confirm other circuits operate normally.
* Focus investigation only on the suspect circuit.

---

=== 5. Break Down The Circuit (Section Testing) ===
* Disconnect all loads (sockets, appliances, accessories).
* Test RCD again with circuit energised but unloaded.
* If it now holds:
* Fault is in a device or appliance

If it still trips:
* Fault is in fixed wiring

---

=== 6. Appliance Check (If Socket Circuit) ===
* Unplug everything on the circuit.
* Pay attention to:
* Washing machines
* Dishwashers
* Kettles
* Outdoor tools and garden equipment
* Plug appliances back in one at a time to identify the faulty item.

---

=== 7. Fixed Wiring Checks ===
* Visually inspect:
* Sockets (especially outdoor or damp areas)
* Junction boxes
* External lighting
* Look for signs of:
* Water ingress
* Heat damage
* Crushed or pinched cables
* Check for neutral-to-earth contact faults.

---

=== 8. Test For Cable Faults ===
* Carry out insulation resistance testing on suspect circuit.
* Test between:
* Live and earth
* Neutral and earth
* Live and neutral
* Look for low insulation resistance readings indicating leakage.

---

=== 9. Check For Neutral Issues In Board ===
* Inspect neutral bar carefully.
* Look for:
* Loose neutrals
* Borrowed neutrals between circuits
* Incorrect neutral pairing on RCBOs
* Especially common after consumer unit changes.

---

=== 10. RCD Condition Check ===
* If no fault is found in wiring or appliances:
* Test RCD using appropriate test equipment
* Check trip times and sensitivity
* Replace RCD if it fails tests or behaves inconsistently.

---

== Common Real-World Causes ==
* Outdoor socket full of water
* Fridge/freezer developing earth leakage when compressor starts
* Boiler or immersion heater insulation breakdown
* Damaged garden lighting cable
* Washing machine heating element leaking to earth
* Shared neutral mistakes after alterations

---

== JME Standard ==
All RCD faults must be traced systematically by elimination, ensuring circuits, appliances, and protective devices are checked in a controlled and safe manner before replacement or repair decisions are made.

New page

= Consumer Unit Replacement Procedure =

== Purpose ==
To safely replace an existing consumer unit with a new unit, ensuring all circuits are correctly reconnected, protected by the appropriate protective devices, and left in a safe working condition.

== Procedure ==

=== 1. Confirm The Scope Of Work ===
* Identify the existing consumer unit and all outgoing circuits.
* Check for signs of damage, overheating, or outdated equipment.
* Confirm whether the replacement is like-for-like or an upgrade (e.g. split load to all RCBO).
* Take clear photos of the existing setup before any work starts.

---

=== 2. Isolate The Supply ===
* Follow the JME Safe Isolation Procedure.
* Isolate the incoming supply at the main switch or service cut-out (if authorised).
* Lock off and label the supply.
* Prove dead at the consumer unit using approved test equipment.
* Confirm all circuits are dead before touching any conductors.

---

=== 3. Remove Existing Consumer Unit ===
* Remove cover and identify all outgoing circuits.
* Label cables clearly if not already identified.
* Disconnect outgoing circuits one at a time.
* Inspect all conductors for:
* Damage or overheating
* Brittle insulation
* Loose or poor terminations
* Remove the old consumer unit once fully disconnected.

---

=== 4. Prepare New Consumer Unit ===
* Fix new consumer unit securely in position.
* Ensure there is enough space for safe cable routing and termination.
* Check incoming tails are suitable for reuse or require replacement.
* Prepare all circuit cables for termination.

---

=== 5. Device Layout (MCBs vs RCBOs) ===

==== MCB (Miniature Circuit Breaker) ====
* Provides protection against:
* Overload
* Short circuit
* Typically used where circuits share an RCD (e.g. split load boards).
* Does not detect earth leakage faults on its own.
* Multiple circuits are protected by a single RCD upstream.

==== RCBO (Residual Current Breaker with Overload Protection) ====
* Provides individual protection for each circuit:
* Overload protection
* Short circuit protection
* Earth leakage protection (RCD function built in)
* Each RCBO protects a single circuit independently.
* Reduces nuisance tripping affecting multiple circuits.

==== Neutral Flylead (RCBO Setup) ====
* Most RCBOs require a neutral connection via a flylead.
* The flylead connects the RCBO to the neutral bar in the consumer unit.
* Each circuit has its own neutral directly associated with its RCBO.
* Care must be taken to ensure:
* Correct neutral pairing per circuit
* No cross-connected neutrals between circuits

---

=== 6. Reconnect Circuits ===
* Reconnect circuits one at a time.
* Ensure correct assignment to:
* MCBs (line protection only)
* RCBOs (line + neutral protection per circuit)
* Tighten all terminals securely.
* Keep wiring neat, separated, and under no strain.
* Ensure neutrals are correctly paired (especially with RCBOs and flyleads).
