Temporary Power for Weddings & Events in Nepal: Setup Guide
Temporary power setup for weddings and events in Nepal: cable sizing, distribution boards and electrician costs in Kathmandu. NPR rates 2026 from SDR Smart Design and Repair — 9801508528.
What temporary power for a Nepali wedding involves
A Kathmandu wedding pulls more power than the venue was ever wired for: a band and sound system (1–3 kVA), LED and stage lighting rigs (2–6 kVA), caterers running chafing warmers, ovens and fridges (3–10 kVA), marquees and garden lights, plus charging stations and fans. Add a generator because NEA supply or venue capacity will not hold the peak, and you now have two sources, long cables across walkways, and hundreds of guests — the ingredients of a shock incident or a mid-mehendi blackout.
Temporary power done properly means one plan: total load calculated, source sized with headroom, cable sized for distance, a temporary distribution board with MCBs and RCD protection, everything ramped where it crosses paths, and a qualified electrician on call through the event. SDR Smart Design and Repair sets up event power across Kathmandu, Lalitpur and Bhaktapur — plan yours on 9801508528.
- Sound and DJ: 1–3 kVA
- Stage and LED lighting: 2–6 kVA
- Catering (ovens, warmers, fridges): 3–10 kVA
- Fans, marquee lights, charging: 1–4 kVA
- Always size the source ≥ total load × 1.25
- Guests + cables + water: treat every run as a trip hazard
Temporary distribution board, RCD and MCB protection
The heart of a safe temporary setup is a proper distribution board — not a wall of daisy-chained strips. A temporary DB gives you a main isolator, one MCB per branch (sound, lights, catering, misc), and a 30mA RCD or RCBO on the circuits where people and water meet: outdoor sockets, marquee lighting and anything near the catering wash area. That board is what turns a faulty fairy-light string into a single tripped breaker instead of a live cable in the lawn.
Hiring or building a temporary board with RCBOs in Kathmandu costs Rs 3,000–8,000 per event day depending on way count; a full event package with board, cables and electrician runs Rs 8,000–25,000 for a typical wedding. Test the RCD TEST button before guests arrive and assign one person — ideally the event electrician — who knows where the board is. SDR can staff the board for the duration or hand over a labelled, tested setup your venue caretaker can manage.
- Main isolator + MCB per branch circuit
- 30mA RCD/RCBO on all outdoor and wet-area circuits
- Press TEST on the RCD before doors open
- Board off the ground, covered if outdoors, labelled
- Never daisy-chain strips as “distribution”
Cable sizing and routing for long venue runs
Long runs are where temporary setups fail: voltage drops so far down the garden that the sound cuts out, or the cable heats because it is undersized for the distance. Rule of thumb for 230V single-phase at event loads: up to ~15 m at 16A can often run 2.5 mm², 15–30 m should step to 4 mm², 30–60 m wants 6–10 mm², and generator-to-DB runs over 50 m with heavy load need 10–16 mm² or a closer generator. When in doubt, upsize — cable is cheaper than a ruined event.
Routing matters as much as size. Keep cables out of walkways where possible; where crossing is unavoidable, use cable ramps or mat covers (Rs 300–800 per crossing point) and tape down the rest. No cable through standing water, no joints lying in grass overnight without a raised junction box, and keep the generator upwind of guests with an earth connection. SDR supplies rated cable sets, ramps and a route plan with every hire — quote on 9801508528.
- ≤15 m: 2.5 mm² minimum; 15–30 m: 4 mm²
- 30–60 m: 6–10 mm²; long/heavy: 10–16 mm²
- Cable ramps on every walkway crossing (Rs 300–800 each)
- No joints in puddles — raised, covered junctions only
- Generator: earthed, ventilated, upwind, fuel managed
Hire costs: event electrician and equipment (NPR)
Budget the electrical scope like any other vendor line. Event electrician attendance in Kathmandu runs Rs 3,000–8,000 for the setup day, and Rs 1,500–4,000 per additional day or evening on call. Temporary DB and cable package hire for a standard wedding is Rs 5,000–15,000 per day; generator hire varies by kVA (ask us for current rates with delivery). Extra wall-point extension leads, distribution boxes and ramp sets add Rs 1,000–4,000 depending on quantity.
A full managed setup — load plan, generator interface, DB, all cabling, on-call electrician for the event — typically lands at Rs 15,000–45,000 for a mid-size Kathmandu wedding, and scales with catering load and lighting rigs. Compare that to the cost of one cancelled evening: power failure during the reception, damaged sound equipment, or a shock incident. SDR gives an itemised event NPR quote after a venue visit or clear photos and measurements.
- Event electrician (setup day): Rs 3,000–8,000
- On-call evening rate: Rs 1,500–4,000
- DB + cable package hire/day: Rs 5,000–15,000
- Ramps, leads, junction boxes: Rs 1,000–4,000
- Full managed wedding package: Rs 15,000–45,000
Event-day safety checklist
Run this list before the first guest arrives and again if weather turns. Walk the venue with the electrician: confirm the total load against the source, test every RCD, check all crossings are ramped, verify no cable sits in water paths, confirm the generator earth and fuel store, and note the location of the main isolator in your head — tell the venue manager and the caterer lead too. During the event, nobody but the assigned person opens the board.
If rain starts: kill outdoor socket circuits first, inspect ramps for pooling water, and move any junction boxes that are not rated wet. Keep SDR’s number on the event contact sheet so a fault is fixed in minutes, not by a well-meaning cousin with tape. Pre-event plan and booking: call or WhatsApp 9801508528, or reserve a date at /#booking. Background on why RCDs matter: /blog/electrical-fire-prevention-home-nepal.
- Load plan vs source capacity confirmed (×1.25 headroom)
- Every RCD TEST pressed and passed before doors open
- All walkway crossings ramped and taped
- Caterer, venue manager and DJ know isolator location
- Rain plan: outdoor circuits killed, boxes checked
- Electrician contact on the event run sheet: 9801508528
