One Room Has No Power in Nepal: Tracing the Fault
One room has no power in Nepal while the rest of the house works? Likely tripped way, loose joint or broken cable. Kathmandu fix by SDR 9801508528.
Why only one room goes dead
When one room loses power while the rest of the house carries on normally, the fault is almost always local — a single circuit, a single way in the distribution board, or a single junction between the board and that room. That is good news: the scope is bounded, the diagnosis is usually quick, and the repair is rarely a whole-house rewire. What it is not is something to live with for weeks while you run extension cords from the hallway.
SDR Smart Design and Repair traces dead-room faults across Kathmandu on every kind of wiring — concealed conduit in plaster, surface trunking in older flats, and mixed generations of accessory where one renovation cut into another’s circuit. The pattern of what still works (lights? sockets? ceiling fan?) tells us where to look before a screwdriver comes out, which is why the first questions on 9801508528 are always about exactly what is dead and what is fine.
- Whole room dead = check the board way first
- Only sockets dead, lights fine = socket circuit or last joint
- Only lights dead = lighting way or ceiling rose chain
- Dead after renovation = suspect a cut cable
Step 1: check the distribution board
Start at the distribution board with the power still on for the rest of the house. Look for a breaker that has tripped to the middle or off position — some boards trip only slightly, and a visually identical MCB row can hide one that is not fully on. Switch it firmly OFF then ON once; if it immediately trips again, stop and call an electrician, because that means a real fault downstream (short, water, failed appliance) is still present.
If nothing is obviously tripped, check whether the room is fed by a way that is off at the main, a fused switch that has blown, or — in older Kathmandu boards — a porcelain fuse with a melted element. Also look for scorch marks or a way that feels warm at the cover. Note which way you believe feeds the room; if the board is unlabelled, that itself is part of the problem and we label it when we leave.
- Find and firmly reset the tripped MCB once
- It trips again immediately → do not keep resetting; call
- Check fused ways and old porcelain fuses
- Warm or scorched way = urgent, switch off and call
- Unlabelled board → label it during the repair visit
Step 2: isolate what is actually dead
Walk the room with a phone light and test every point: ceiling light, wall lights, each socket, the fan, any connected appliances. Write down what is dead and what is alive. Sockets dead with lights working tells us we are on the socket circuit; the reverse points to the lighting way or the ceiling-rose chain feeding the pendants. Partial death — say two of four sockets — usually means a junction or a daisy-chained accessory has failed rather than the whole run.
Also test the room next door and any outdoor point that might share the run: faults often show up one room downstream of where the break actually happened. This map of dead and alive points is exactly what SDR wants when you call — describe it, or send a short video, and we arrive knowing whether to bring MCBs, cable, junction accessories or all three.
- Test every socket, light, fan and fixed appliance
- Sockets dead + lights alive → socket circuit path
- Lights dead + sockets alive → lighting way or rose chain
- Two of four sockets dead → local junction/chain break
- Map neighbouring rooms and outdoor points too
Common causes: joint failure, cut cable, failed MCB
The three causes we find most often. First, a loose or burnt joint — usually in a ceiling rose, a junction box or the switch feed — where a terminator finally let go; the symptom is a dead run with no trip because the circuit opened rather than shorted. Second, a cable cut or crushed during someone else’s work: drilling for a shelf, chasing a channel, a nail through conduit during a curtain-rail install. Third, an MCB that has failed open (or a way whose internal contact has burnt) so it looks on but passes nothing.
Less common: water ingress after monsoon rain tracking into a ceiling box, a rodent-chewed cable in a roof void, or a renovation where a circuit was deliberately abandoned with tape. Each leaves a different signature, and the fix price follows the cause — not the symptom you called about.
- Open/burnt joint in rose, switch or junction box
- Cable cut or crushed by drilling/chasing
- Failed MCB passing no current despite looking on
- Monsoon water into a ceiling box; rodent damage in voids
- Renovation leftovers: abandoned taped-off circuits
What the repair costs in NPR (Kathmandu)
If the cause is a tripped breaker or a simple re-terminate at a rose or switch, expect NPR Rs 800–2,000 including the visit on a standard daytime booking — often fixed on the first call-out. A failed MCB replacement lands around Rs 1,200–2,500 all-in. Locating and repairing a cut cable in accessible conduit or surface run typically runs Rs 2,000–6,000 depending on how much cable must be replaced and how the wall is finished.
Concealed cable faults that require chasing, making good and re-plastering sit higher — Rs 4,000–10,000+ with finish work coordinated. If the board turns out to be the issue (full, failing, or needing a way added), we separate that scope so you can approve the room repair first and decide on the panel separately; board work follows /services/panel-upgrades. Every SDR quote itemises cable, accessories, labour and testing before we start.
- Re-terminate / reset fault: Rs 800–2,000 typical
- Failed MCB replaced and tested: Rs 1,200–2,500
- Accessible cut cable repair: Rs 2,000–6,000
- Concealed fault + make-good: Rs 4,000–10,000+
- Itemised quote before chargeable work begins
When to stop DIY and call SDR
Stop at the board. If a breaker will not stay on, if you smell anything hot, if the dead room came after drilling or water ingress, or if you are unsure which way to switch — stop and call. The tests between board and fault involve live parts, and guessing which conductor is which in an unlabelled Kathmandu board is how good DIY intentions end in a shock. Extension cords bridging the dead room meanwhile add their own risk every day they stay in service.
