Preventive Electrical Maintenance for Factories and Commercial Buildings
Scheduled inspection, testing and servicing to catch faults before they cause breakdowns. Monthly, quarterly or semi-annual schedules. Written report after every visit.
What does Preventive Maintenance include?
The difference between a factory that rarely has electrical breakdowns and one that regularly loses production to tripped panels or burnt motors is almost always maintenance discipline. Preventive maintenance catches deteriorating insulation, loose terminations, high earth resistance and overloaded circuits before they fail. It is cheaper than breakdown repair, and far cheaper than the production loss that accompanies an unplanned shutdown. We run scheduled preventive maintenance programs for factories, hotels, schools and commercial buildings in Chh. Sambhajinagar (Aurangabad).

Maintenance schedule calendar - dates fixed for the year in advance
- 3
Each visit follows a printed checklist covering all scope items
- 4
Test readings recorded in a maintenance log (date, readings, observations, actions)
- 5
Corrective actions within scope (tightening, cleaning, minor adjustments) done in the same visit
- 6
Defects beyond scope (cable replacement, breaker replacement, re-wiring) documented and quoted separately
- 7
Written visit report issued within 24 hours

How does the Preventive Maintenance process work?
From inquiry to handover. Steps may vary depending on project size and site-specific conditions.
Initial baseline visit
First visit establishes a baseline. We record IR values, earth-resistance readings and load balance measurements. Any defects found in the baseline are documented and discussed before starting the preventive program.
Maintenance schedule
Dates for the year are fixed in advance based on the agreed frequency (monthly, quarterly, semi-annual). You know when to expect us and can plan any partial shutdown if required.
Each visit - checklist execution
We follow the agreed checklist. Every item is ticked off with a reading or observation. We do not just look and leave - we tighten what is loose, clean what is dirty and test what needs testing.
Visit report
Within 24 hours: observations, test readings, corrective actions taken in the visit, pending recommendations that need further work. You have a written record of what was done and what remains.
Defect follow-up
Defects requiring parts or major work are quoted separately. You decide what to proceed with and when. We track open items across visits so nothing falls through.
Annual summary
End of year: summary of all visits, trend in IR and earth-resistance values, recommendations for capital replacement or system upgrades that the maintenance program identified.
Indian Standards we align with
Our work for this service is aligned with the following Indian Standards and statutory regulations.
- IS 732:2019 - Wiring installations (inspection and maintenance sections)
- IS 3043:2018 - Earthing (periodic testing requirement)
- IS 5216 - Safety procedures for electrical work
- IS 13947 - Maintenance of low-voltage switchgear and controlgear
- IE Rules 1956 - Rule 61 maintenance obligations
What differentiates us
Honest differentiators - what we actually do differently.
- Written report every visit - not a verbal update. You have documentation for auditors, insurers and your own maintenance records.
- We track readings over time - a deteriorating IR value or rising earth resistance catches a developing problem before it fails.
- Fixed schedule planned a year ahead - you know when the visit is coming, not just when we have a free slot.
- We separate what we fix in the visit from what needs a separate contract - no bundled surprises.
- Applies to both electrical safety (earthing, protection) and equipment longevity (motors, switchgear, cables).
Common questions about this service
If your question is not here, WhatsApp us directly - we will give you a straight answer.
How often should electrical preventive maintenance be done?
Depends on the facility and the load. A factory running three shifts with heavy motor load should have monthly checks on critical circuits and quarterly full maintenance. A hotel or school typically manages well with quarterly visits. A small office building may need only semi-annual checks. We assess the facility and recommend a schedule based on what is there, not a default frequency that may not be appropriate.
What is the difference between preventive maintenance and breakdown maintenance?
Preventive maintenance is scheduled and proactive - you visit regularly, find developing faults (loose connections, degrading insulation, rising earth resistance) and fix them before they fail. Breakdown maintenance is reactive - you respond after the failure. Breakdown maintenance costs more because it is unplanned, often happens at inconvenient times, and always involves some production or operation loss. Preventive maintenance has a visible cost; breakdown maintenance has a hidden one that is usually much higher.
Do you carry out the maintenance work or just inspect and report?
We do both. During the visit, we perform the maintenance - tightening, cleaning, testing. Minor corrective work (tightening a loose termination, replacing a damaged cable end) is done in the visit. Larger work (replacing an MCCB, rewiring a circuit) is documented and quoted separately. You decide what to proceed with.
What instruments do you use for preventive maintenance?
A calibrated digital insulation resistance tester (megger) for IR testing. A calibrated three-point earth tester (not a continuity tester) for earth-resistance measurement. A calibrated RCCB/ELCB tester for trip-time verification. A clamp meter for load and three-phase balance measurement. We do not do visual-only maintenance and call it a check.
Can you maintain our factory in Waluj MIDC?
Yes. Waluj MIDC, Shendra MIDC, Chikalthana MIDC and the broader Chh. Sambhajinagar area are all within our regular service range. For factories in MIDC with continuous production, we coordinate visit timing with your maintenance team so the right circuits can be isolated safely.
