3 Phase Electrical Installations in Woodbridge , Suffolk

A single-phase supply uses two wires (live and neutral) and is standard for homes. A 3-phase supply uses four wires (three live and one neutral) and provides three times as much power. It is essential for industrial machinery and large commercial buildings because it delivers a constant, steady stream of power that doesn't "pulse" like single-phase electricity.

If you are frequently tripping breakers, noticing flickering lights when large machines start, or planning to install high-draw equipment like commercial ovens or vehicle lifts, you likely need an upgrade. We can perform a load analysis on your current system to see exactly how much headroom you have left.

Every project is different, but a standard distribution board upgrade or a new circuit installation can take anywhere from a few days to a couple of weeks depending on the size of the building and the complexity of the cable runs. We always provide a clear timeline before we start work so you can plan your operations.

We aim to keep your business running. While there will be a period where the power needs to be turned off to connect the new system, we can often schedule this for weekends or evenings to avoid disrupting your working day.

The electricity itself costs the same per unit, but the 3-phase system is often more efficient for large motors. This means your machinery uses the power more effectively, which can lead to lower energy bills despite the increased capacity.

If you are regularly tripping your main breakers, or if you are planning to install equipment like large air conditioning units, commercial car chargers, or heavy industrial machinery, you likely need 3-phase power. Most "industrial" grade equipment specifically requires a 3-phase supply to operate. We can perform a load assessment to give you a definitive answer.

A full fit-out usually starts with the main 3-phase distribution board. From there, we install the necessary containment (like conduit or trunking) to run power to different zones. This includes high-bay lighting, power for conveyor systems, office area circuits, and specialized outlets for machinery. We manage the project from the empty shell stage through to the final testing and handover.

Yes. We specialise in industrial machinery wiring. Every machine has different start-up currents and load requirements. We make sure the cabling and switchgear are correctly rated for the specific gear you are running, preventing overheating and ensuring the machine operates at its peak performance.

It varies depending on the size of your building and the complexity of the work. A simple distribution board upgrade might take a day, while a full warehouse fit-out could take several weeks. We always provide a clear timeline before we start so you can plan your business operations accordingly.
