Our verified electricians provide safe, code-compliant installations.
UPS & Backup Power Electrical Services
- Dedicated UPS Distribution Board Wiring: Separating heavy power points (ACs, geysers, motors) from delicate backup circuits (fans, LED lights, routers).
- Manual & Automatic Changeover Switches: Installing heavy-duty 32A/63A rotary or automatic changeover switches for seamless shifting between WAPDA, UPS, and generators.
- Neutral Wire Loop Troubleshooting: Eliminating shared neutral faults that cause phantom electricity meter running or inverter overload beeping.
- Heavy Battery Cable & Terminal Lugging: Installing thick copper battery cables with hydraulic crimped lugs to prevent terminal melting and resistance drop.
- Solar Inverter AC/DC Breaker Integration: Fitting DC circuit breakers, surge protectors, and isolation switches for hybrid inverter setups.
Safety Risks of Substandard UPS Wiring
Faulty UPS wiring is one of the leading causes of residential electrical fires in Pakistan:
- Shared Neutral Backfeeding: When an inexperienced electrician combines WAPDA neutral with UPS neutral, current backfeeds through your wiring, spinning your digital meter even when power is off.
- Undersized Battery Cables: Drawing 100+ amps through thin 10mm or 16mm wires generates intense heat, melting insulation and damaging expensive tubular batteries.
- Lack of Dedicated Breakers: Without a dedicated single-phase breaker between the distribution board and UPS input/output, a household short circuit can permanently destroy your inverter’s main motherboard.
Fixed Rates & Transparent Diagnostics
- Electrician Visiting Fee: Fixed Rs. 500 inspection charge across Islamabad and Rawalpindi.

Frequently Asked Questions
Can I connect my refrigerator or washing machine to my home UPS?
Standard 1kVA/2kVA household UPS units are designed for inductive light loads (fans, lights, TVs, computers). Heavy compressor loads require larger 3kVA+ pure sine wave solar/hybrid inverters with adequate battery bank capacity.
Why does my UPS make a continuous beeping sound?
Continuous beeping typically indicates overload (too many appliances running), low battery voltage, poor battery terminal contact, or an internal inverter fault.
Do you install automatic changeover switches?
Yes. We install dual-power automatic changeover switches that shift your home circuits between WAPDA and your alternate backup source in milliseconds without dropping your computer or TV.
