We provide industrial electrical services for facilities with serious power requirements. 

Heavy machinery, production equipment, and large-scale operations all require reliable electrical infrastructure to operate. Our licensed electricians work across Sydney and regional NSW, handling high-capacity installations, repairs and maintenance that industrial environments demand.

Industrial electrical work is about ensuring your facility has reliable, correctly distributed power exactly where it’s needed to support production, safety, and growth. When you’re expanding operations or installing new equipment, your existing electrical supply often can’t handle the additional load.

What we handle:

  • Sub-board installations and electrical distribution
  • Three-phase power for heavy equipment and machinery
  • High-capacity cable runs and power upgrades
  • Factory and warehouse lighting installations
  • Switchboard relocations and capacity expansions
  • Electrical infrastructure for production equipment

We assess your current electrical setup, calculate what’s needed for your operations, and install infrastructure that delivers reliable power. Work is scheduled around your production to minimise downtime.

FREQUENTLY ASKED QUESTIONS
Can you assess whether our current electrical system can handle new equipment?

Answer

We assess your existing electrical capacity, calculate the load requirements for new equipment, and determine if your current setup is adequate or needs upgrading. This includes checking main switchboards, sub-boards, and cabling capacity.

Do you need to shut down our facility to do electrical work?

Answer

It depends on the scope of work. Some installations can be done in sections while other areas keep operating. For major switchboard work or main supply upgrades, partial or full shutdowns may be necessary. We discuss options during assessment and schedule work to minimise impact.

How long do industrial electrical installations typically take?

Answer

Project duration depends on the scope. Installing a sub-board might take a few days, whereas running three-phase power to new machinery could take a week. Generally, large-scale facility upgrades can take several weeks. We provide realistic timeframes once we understand what’s involved.

Can you handle electrical work for facilities that operate 24/7?

Answer

We’ve worked in facilities with continuous operations. The work gets staged in sections, scheduled during lower-production periods, or coordinated around maintenance windows. It requires more planning, but it’s manageable.

Do you provide emergency electrical services for industrial facilities?

Answer

We offer same-day service and 24/7 emergency callouts. When electrical issues shut down production or affect critical systems, response time matters. We prioritise industrial emergencies because we know what downtime costs.

What's involved in upgrading three-phase power for heavy machinery?

Answer

We assess the machine’s power requirements, verify that your existing three-phase supply has sufficient capacity, and install the necessary wiring, isolation switches, and protection. If the main supply is inadequate, we coordinate level 2 upgrades with our subcontractors to increase grid capacity.
