3-Phase Distribution Board
Industrial-grade distribution boards for workshops, barns, and machinery. We install proper MCBs, RCDs, and motor starters to BS7671 standards.
- Industrial Enclosures (IP65)
- Motor Protection Devices
- Surge Protection (SPD)
And Much More...
We also install generator changeover switches, soft starters for large motors, VFDs (variable frequency drives), backup supplies, and commercial workshop fit-outs. Any heavy power requirement, we can handle.

High Voltage Specialist.
I served as a Retained Firefighter with Brechin Fire Service and a Royal Air Force Electrical Engineer. I have worked with three-phase power systems for 30 years.
Three-phase power is dangerous - 415V kills instantly. I don't let apprentices wire distribution boards unsupervised. When I install a 3-phase supply for your farm, I ensure proper phase rotation, earthing, and motor protection. Your machinery runs smoothly, and your insurance stays valid.

Why Your Farm Needs Three-Phase Power
Single-phase supplies cannot handle heavy farm machinery. Here is why three-phase is essential.
3x Power
Capacity
Three-phase delivers three times the power of single-phase for the same cable size. Essential for grain dryers, workshop lathes, and milking equipment.
Smoother
Motor Running
Three-phase motors run smoother, quieter, and longer than single-phase equivalents. Less vibration means less wear on bearings and gearboxes.
Lower
Running Costs
Three-phase motors are 10-15% more efficient than single-phase. Over years of operation, this saves thousands in electricity costs.
Balanced
Electrical Load
When properly balanced, three-phase puts equal load on all three cables, preventing overheating and reducing voltage drop.
What Happens When Phases Are Unbalanced?
Unbalanced three-phase loads cause serious problems and cost you money.
Phase A (Overloaded)
95A
Cable overheating
Phase B (Underloaded)
45A
Wasted capacity
Motor Burnout
Unbalanced phases cause excessive current draw, burning out motor windings.
Neutral Overload
Imbalance forces current through the neutral, causing cable damage and fire risk.
High Electricity Bills
Unbalanced systems waste power and may incur penalty charges from SSEN.

Safety Warning: Three-Phase Power Is Dangerous
415V kills instantly. Three-phase installations require specialist knowledge of phase rotation, motor protection, and earthing. DIY installations kill people and invalidate your insurance.
We install three-phase systems to BS7671 with proper RCD protection, isolation, and earth fault monitoring. Your machinery runs safely, and your insurance stays valid.
OurThree-Phase Installation Process
From SSEN application to final commissioning and certification.
Load Assessment
We calculate your total load requirements including motors, heaters, and future expansion. This determines the supply size you need from SSEN.
SSEN Application Support
We handle all paperwork for SSEN (Scottish & Southern Electricity Networks) including connection applications, wayleaves, and meter point arrangements.
Installation
Once SSEN installs the supply, we install your distribution board, motor circuits, and earthing system. All work is tested and certified to BS7671.
Commissioning
We test phase rotation, balance loads, set motor protection devices, and commission all equipment. You receive full electrical certificates.
Equipment We Regularly Install 3-Phase Power For
Three-Phase Installation FAQs
? How long does the SSEN application process take?
Typically 6-12 weeks depending on your location and the supply capacity required. We submit applications on your behalf and chase SSEN throughout the process.
? How much does a new three-phase supply cost?
SSEN charges vary widely (£2,000-£10,000+) based on distance from the nearest transformer and capacity required. We provide accurate estimates after a site survey.
? Can I upgrade from single-phase to three-phase?
Yes. We handle the SSEN application, install a new meter, and upgrade your internal wiring. Your existing single-phase circuits continue to work alongside the new 3-phase supply.
? What is phase rotation and why does it matter?
Phase rotation determines which direction three-phase motors spin. Incorrect rotation damages pumps and fans. We test and correct rotation on all motor circuits.
? Do I need a generator backup for my farm?
If you have dairy cattle or grain in dryers, yes. We install automatic changeover panels that switch to generator power within seconds of a mains failure.
? What size three-phase supply do I need?
We calculate this based on your motor sizes and simultaneous usage. A typical small farm needs 60-100A, while large dairy farms may need 200A+ supplies.
? Can I run single-phase equipment from a three-phase supply?
Yes. We design distribution boards with both three-phase and single-phase circuits, allowing you to power lights, sockets, and 230V equipment from the same supply.
? What happens if my phases are unbalanced?
Unbalanced phases cause motors to overheat, increase electricity costs, and damage cables. We measure current on all three phases and redistribute loads to achieve balance.
? Do I need surge protection on a three-phase supply?
Yes, especially for farms with overhead power lines. We install SPDs (Surge Protection Devices) to protect expensive motors and control equipment from lightning strikes.
? Can you install a soft starter for large motors?
Yes. Soft starters reduce the initial surge current when motors start, preventing voltage dips and extending motor life. Essential for grain dryers and large pumps.
? What is a VFD and when do I need one?
VFDs (Variable Frequency Drives) allow you to control motor speed, saving energy. Useful for ventilation fans, pumps, and conveyors that don't need to run at full speed constantly.
? How do you ensure my three-phase installation is safe?
We follow BS7671 regulations, install proper RCD protection, test earth resistance, verify phase rotation, and commission all equipment. You receive full electrical certificates for insurance.
