Submains Upgrades in Townsville
Looking to upgrade your submains in Townsville? GAP Industries North Queensland delivers certified installations across residential, commercial and industrial environments.
From multi-unit developments to rural sites and high-demand facilities, we ensure your electrical distribution is built to handle current and future loads. We ensure they’re installed safely and in line with all regulations.
We partner with developers, contractors and site managers to upgrade outdated or undersized submains, ensuring cable sizing and voltage integrity meet AS/NZS 3000 standards.
Why Submains Matter for Safety and Reliability
Submains connect your main switchboard to other areas of your site, such as detached buildings or secondary switchboards. When undersized or faulty, they can cause voltage drop, circuit overloads or safety hazards.
Upgrading ensures:
- Stable voltage across longer distances
- Support for added loads or new tenants
- Alignment with current safety standards
- Reliable performance for critical infrastructure

FREQUENTLY ASKED QUESTIONS
What is a submain in an electrical system?
It’s a cable or circuit that connects your main switchboard to a remote board or building on your site. Submains distribute power over distance and must be properly sized to avoid risks.
How do I know if my submains need an upgrade?
If you’re adding load, expanding a facility, or seeing symptoms like flickering lights or tripped breakers, your system might be undersized. We assess and recommend necessary changes.
Can undersized submains be dangerous?
Yes. They can overheat, drop voltage, or fail. This can lead to serious safety risks or damage to equipment.
What properties benefit from submains upgrades?
Sites with multiple buildings, long cable runs, or increasing demand: residential complexes, rural estates, industrial plants and commercial precincts.
How much does a switchboard upgrade cost?
Costs vary based on the type of property, existing system condition and electrical load.
We provide transparent quotes after assessing your site, with no hidden fees.
How long does a submains upgrade take?
Timeframes depend on access and system complexity. After assessment, we provide a clear project scope and schedule.
Are submains upgrades mandatory?
They’re required when the existing system doesn’t meet safety, load or wiring rules. Upgrades ensure compliance and performance.
Do you provide certification after the upgrade?
Yes. We test and certify all works, issuing compliance documentation to meet Australian standards.
