Dedicated power supplies for production machinery, fabrication kit, packaging lines and process plant. Sized to the load with proper isolators, fused spurs and containment. Installed around your shifts.
new machine arrives on site. The production manager wants it running by Monday. The electrician throws a sub-main off the nearest distribution board, hangs a local isolator, and walks away. Six months later the machine is tripping intermittently, the connection has loosened from thermal cycling, and nobody can explain why.
Industrial machine supplies fail in predictable ways. Undersized cables run hot. Cheap isolators wear out. Containment held up with cable ties drops out of the ceiling void in the first heatwave. The supply that worked on day one isn’t the supply that’s still working in year three.
We do industrial machine supplies the way machinery manuals say they should be done – cables sized for full load current plus an allowance, isolators rated correctly with appropriate breaking capacity, proper galvanised tray or trunking on the cable run, emergency stops where the risk assessment requires them.
We also do this around your shifts. New machine power supplies usually mean a few hours of localised downtime to make the final connection. We schedule that downtime to fit your operations – most installs are made live during a planned changeover or out-of-hours window.
Every supply tested for insulation resistance, polarity, loop impedance and RCD operation. Minor works certificate issued before we leave site.
We walk the proposed location, identify the nearest suitable supply, measure cable run, identify containment route and assess any safety integration requirements.
Quote covers cable, containment, isolator, protection, testing and certification. Where there are routing options both are priced.
Final connection window scheduled around your shifts - usually a planned changeover, weekend or short out-of-hours window. Cable and containment go in live.
Cable run installed in containment, isolator mounted, final connection made during the agreed downtime window. Machine commissioned and load-tested.
Minor works certificate issued, supply schedule updated at the distribution board, isolator labelled, warranty documentation provided.

Galvanised tray or trunking – never cable ties
A typical single machine supply with a moderate cable run is two days – one for cable and containment install, one for final connection and testing. Larger machines or longer runs scale up from there.
Cable runs and containment can almost always go in while the line is running. Final connection requires a short isolation window – usually a couple of hours, scheduled around your operations.
If the new machine takes the building’s total load above existing supply capacity we’ll lodge the DNO application and handle the liaison. DNO lead times are typically 4-8 weeks.
Yes – where the machine safety case requires interlocked isolators we install those and wire the safety circuit per your risk assessment.
We size cables based on full load current per BS 7671, with appropriate de-rating factors for ambient temperature, run length, grouping and method of installation. Usually one cable size up from absolute minimum, for thermal headroom.
Yes – most production machinery is three-phase. We do single-phase and three-phase machine supplies as standard. See our separate page on 3-phase installations for new supply work.
