Downtime is expensive. Good electrical work prevents it.
Businesses and facilities need power that's safe, compliant and dependable. We design, install and maintain electrical systems that keep production lines, cold rooms, kitchens and offices running.
Our team handles new installations, expansions and retrofits, as well as rapid-response repairs when something fails. We work around your operating hours to minimise disruption, including nights and weekends.
- Three-phase supply, balancing and power distribution
- Motor circuits, starters, VFDs and control panels
- Preventive maintenance and thermal inspections
- After-hours and emergency call-outs
What we install & repair
Distribution boards
Main and sub-distribution boards, busbars, MCCBs, metering and panel replacements.
Three-phase power
New three-phase supplies, phase balancing, power-factor considerations and load planning.
Motors & controls
Pumps, compressors, conveyors and fans: starters, contactors, overloads and variable-frequency drives.
Commercial fit-outs
Shops, offices, restaurants and hotels: power, data containment, lighting and emergency lighting.
Industrial lighting
High-bay LED, yard and floodlighting, photocell and timer control. Brighter sites, lower bills.
Maintenance contracts
Scheduled inspections, tightening, thermal checks and testing to catch failures before they happen.
Load & current estimator
Estimate the current your equipment will draw. It's useful when planning a new machine, a sub-board or a generator.

*Indicative only, sized at 125% of continuous load and rounded to the next standard rating. Final cable and protection sizing depends on run length, installation method and motor starting currents. We'll confirm on site.
Get it engineered properlySingle-phase vs three-phase
Which supply does your facility need? Here's a practical comparison.
| Factor | Single / split-phase | Three-phase |
|---|---|---|
| Typical use | Homes, small shops, offices | Factories, hotels, large commercial, farms with big pumps |
| Large motors | Limited; higher starting current | Ideal: smoother, more efficient motors |
| Cable size for same power | Larger | Smaller: lower copper cost |
| Installation cost | Lower | Higher upfront |
| Load balancing needed | Two legs | Three phases must be balanced |
| Best when | Load under ~25 kW, few motors | Heavy machinery, chillers, large AC plants |
What a maintenance visit covers
- Visual inspection of boards, cables and enclosures
- Test emergency lighting and exit signs
- Check indicator lamps, meters and alarms
- Generator run test (if installed)
- Thermal (infrared) scan of panels for hot spots
- Phase load readings and balance check
- Motor current draw and vibration observation
- RCD/GFCI trip tests
- Torque check of terminations (with isolation)
- Insulation resistance testing on key circuits
- Earth electrode resistance test
- Written report with prioritised recommendations
Hurricane season prepBefore June, have outdoor panels sealed, surge protection checked and generator changeover tested. After a storm, never re-energise flooded equipment until it's been inspected.
Commercial project workflow
Survey
Site survey, load assessment and review of drawings or existing single-line diagrams.
Proposal
Scope, materials schedule, programme and price, aligned with your operating hours.
Execution
Safe isolation, lock-out/tag-out, staged installation to keep you running.
Commission
Testing, labelling, as-built notes and handover to your facility team.
Commercial & industrial questions
Can you work outside business hours?
Yes. Night and weekend work is common for shutdowns, tie-ins and panel replacements so your operations aren't interrupted.
Do you offer maintenance contracts?
We offer scheduled maintenance plans tailored to your facility: monthly, quarterly or annual visits with written reports.
Our breakers trip when a big motor starts. Can you help?
Motor inrush current can be 6–8× running current. Soft starters or VFDs, correct breaker curves and cable sizing usually solve this. We'll measure and recommend.
Can you upgrade us from single-phase to three-phase?
We can assess your load, prepare the installation and guide you through the JPS supply upgrade process.
