Pakistani Pharmacy / Clinic Backup Power Panel BoM 2026 — UPS, ATS, RCBO Sizing
What backup power does a Pakistani pharmacy or clinic need?
A Pakistani pharmacy/clinic needs three protection tiers: an online double-conversion UPS (3-15 kVA) for vaccine fridge + medical equipment continuity through load-shedding; an ATS-controlled diesel generator (8-25 kVA) for full-site backup; and 30 mA RCBOs on every patient-contact circuit per IEC 60364-7-710 "Medical Locations" requirements. Total backup investment for a typical 5 kW pharmacy: PKR 150K–350K. For a 15 kW clinic: PKR 400K–800K. Investment justification: a single vaccine-fridge failure during 4-hour outage can spoil PKR 100K-500K of stock; one outage event pays for the UPS.
Pakistani pharmacy load profile
| Equipment | Watts | UPS-critical? |
|---|---|---|
| Vaccine fridge (2-8°C) | 120 W (200 W inrush) | YES |
| Insulin fridge (cold-chain backup) | 100 W | YES |
| POS terminal + receipt printer | 80 W | YES |
| CCTV + DVR | 100 W | YES |
| Internet router + WiFi AP | 25 W | YES |
| LED ceiling lights | 200 W | UPS only on emergency lights |
| Air conditioner | 1,800 W | Generator only |
| Water dispenser | 90 W | No |
UPS-critical total: ~425 W — size online UPS at 1 kVA (2-3× headroom for inrush) with 30-min battery autonomy. For a small clinic add ultrasound (250 W), nebuliser (300 W), suction pump (300 W) and oxygen concentrator (350 W) → ~1.5 kVA UPS.
BoM — small Pakistani pharmacy (5 kW total, 0.5 kW UPS-critical)
| Component | Spec | CNC SKU | PKR |
|---|---|---|---|
| Online UPS 1 kVA tower | Pure sine, 30 min runtime | Allied (order) | 35,000 |
| Voltage protector at main | 2P 40A YC7VA | YC7VA-2P 40A | 1,750 |
| Main MCB | 2P 32A C-curve | YCB7-63N | 900 |
| UPS-bypass RCBO | 1P+N 16A 30mA | YCB6HLN 1P+N | 1,750 |
| Branch RCBOs (5 circuits) | 1P+N 16-32A 30mA | YCB6HLN × 5 | 9,000 |
| Type 2 AC SPD | 1P+N 20-40kA 275V | YCS6-B | 2,500 |
| DB enclosure | YCX6 12-way steel | YCX6 | 4,300 |
| Subtotal (pharmacy) | ~55,200 |
Plus a small standby generator (3 kVA petrol or 5 kVA diesel = PKR 70-130K) brings total backup investment to PKR 125-185K. For a multi-room clinic add 15 kVA generator + manual changeover (PKR 220K) and 3 kVA UPS for medical equipment.
Mid-size clinic (15 kW connected, 2 kW UPS-critical) — BoM
- Online UPS 3 kVA tower + extended-battery cabinet for 1 hour autonomy — PKR 110,000
- Voltage protector YC7VA-2P-KWH WiFi 63A at main — PKR 5,200
- Main MCCB 4P 63A YCM7 (3-phase service) — PKR 6,800
- RCBOs per circuit (medical contact = 30 mA, lighting/AC = 100 mA selectivity) — PKR 12,000 total
- ATS YCQ1B 2P 63A for generator switchover — PKR 6,700
- Type 2 SPD 4P 385V at main + 1P+N at UPS output — PKR 8,000
- 15 kVA standby diesel generator — PKR 320,000 (separate from electrical BoM)
- Total switchgear excluding generator — ~PKR 150,000
Why 30mA RCBO is mandatory in medical locations
IEC 60364-7-710 "Medical Locations" requires:
- Group 0 (waiting room, office): standard 30 mA RCD/RCBO on sockets — same as residential.
- Group 1 (consulting room, X-ray, dialysis): 30 mA RCD on socket circuits + redundant earthing + equipotential bonding.
- Group 2 (operating theatre, ICU, cardiology): Medical IT system (isolated, ungrounded) with insulation-monitoring — standard RCBOs replaced with line-isolation monitors.
Most Pakistani pharmacies and small clinics fall under Group 0 / Group 1, where 30 mA RCBO on every socket is sufficient. Hospital ORs and ICUs need the Medical IT system — outside scope of this guide.
Common Pakistani pharmacy/clinic installer mistakes
- Vaccine fridge on a regular line-interactive UPS — switchover transient kills compressor. Use online double-conversion only.
- Skipping voltage protector at main — broken-neutral 415V destroys all electronic equipment simultaneously.
- 30 mA RCBO on the geyser — nuisance trips. Use 100 mA on geyser circuits.
- Sharing UPS output with AC — AC compressor inrush trips UPS bypass. Separate AC to generator-only side.
- No SPD on UPS output — lightning surge propagates through UPS to medical equipment. Add Type 2 SPD downstream.
- Cold-chain failure logging missing — if vaccine spoils, you need temperature log to claim insurance. Use a WiFi temperature data-logger.
