Need power in your garage, shed, or workshop? Voltra Electrical runs dedicated circuits from your main switchboard to outbuildings — with lighting, power points, and a sub-board where needed.
Running power to a garage, shed, or workshop is one of the most common residential electrical jobs we do. Whether you need a few power points and lights for a home workshop, or a full sub-board with dedicated circuits for welders and compressors, Voltra Electrical handles the complete installation. We run underground or overhead cabling from your main switchboard to the outbuilding, install a sub-board with appropriate circuit breakers and safety switches, and fit out the interior with lighting and power points to your requirements. All work complies with AS/NZS 3000 and includes a Certificate of Electrical Safety.
The scope of a garage or shed power installation depends on what you'll be using the space for. A basic setup (lights + 2–3 general power points) can often run from an existing circuit. A workshop with power tools, welders, or compressors needs a dedicated sub-board with individual circuits sized for the equipment. We assess your requirements during the quoting stage and recommend the right approach. Underground cabling is the most common method — we use conduit-protected TPS or XLPE cable buried to the required depth (300mm under concrete, 500mm under soil). Overhead cabling is an option where trenching isn't practical. The sub-board includes its own safety switch (RCD) and circuit breakers, providing independent protection for the outbuilding.
We run cabling underground in conduit (most common) or overhead between buildings. Underground is neater and more protected — we trench to the required depth and backfill after installation.
For basic lighting and a couple of power points, you may not need one. For workshops with multiple circuits or heavy equipment, a sub-board is required — it provides independent safety switch protection and proper circuit separation.
Yes — we install dedicated circuits rated for your specific equipment. Welders and large compressors typically need 15A or 20A dedicated circuits, sometimes 3-phase for industrial equipment.
A basic installation (trench + sub-board + lights + power points) typically takes 1–2 days. Larger workshops with multiple circuits may take 2–3 days.
