Available site capacity
The main switch rating is not always the same as the usable spare capacity available for new machinery. Existing loads and site supply limitations need to be considered.
Workshop Fitouts Victoria
Machinery power installation Victoria
Machinery power should be planned before the machine is delivered, not rushed after it arrives. CNC machines, compressors, hoists, fabrication equipment and industrial machinery can all have specific supply, circuit, isolator and access requirements.
Workshop Fitouts Victoria helps businesses across Victoria coordinate machinery power installation as part of a broader workshop fitout.
We plan machine power around the layout, equipment specifications, service routes, supplier requirements and future workshop use.
Why machinery power needs early planning
A machine can fit physically and still be hard to connect
A machine may fit in the workshop but still be difficult to connect if power, cable routes, isolator positions or switchboard allowances have not been considered.
Early planning helps reduce rework and gives the customer, equipment supplier and trades a clearer pathway.
Workshop Fitouts Victoria helps coordinate machinery power as part of the total workshop setup rather than treating it as a last-minute problem.
Site capacity check
Checking whether the site has enough available power
Before machinery is installed, the available power at the site needs to be understood properly. The rating on the main switch does not always mean that the full amount is available for new equipment. Existing loads, tenancy supply limits, upstream protection, switchboard capacity and how the equipment will be used at the same time can all affect what is actually available.
Workshop Fitouts Victoria can help review the intended equipment list, running loads, startup requirements and likely simultaneous use before the workshop layout is locked in.
This can help identify whether the site may need a power upgrade, staged equipment operation, adjusted machinery selection or equipment with lower running current or lower inrush current. In some cases, choosing the right equipment can reduce the pressure on the available supply and avoid unnecessary issues later.
What to check before installation
Available power considerations
Upstream protection
A circuit breaker, service protection device or supply limitation in an external pillar, meter panel or supply point may be smaller than the main switch inside the building.
Simultaneous equipment use
A workshop may have enough power for one machine at a time, but not enough for all major equipment to run together. Planning should consider how the workshop will actually operate.
Startup and inrush current
Some equipment can draw higher current during startup. Inrush current, starting method and equipment sequencing may affect the power planning.
Equipment selection
Where supply is limited, it may be worth considering machinery or compressor options with lower running load, softer starting characteristics or more suitable electrical requirements.
Early review before leasing
Where possible, site capacity should be reviewed before signing a lease or moving equipment into a factory, shed or warehouse.

Coordinated with the full fitout
Power should support the full workshop layout
Machinery power is only one part of a workshop fitout. It needs to work with lighting, compressed air, data cabling, access, equipment clearances, storage, staff movement and future expansion.
Workshop Fitouts Victoria helps coordinate the power pathway with the broader workshop plan.
FAQ
Common questions
Does the main switch rating tell me how much power is available for new machinery?
Not necessarily. The main switch rating inside the building does not always mean that the full amount is available for new equipment. There may be an upstream circuit breaker, service protection device or supply limitation in an external pillar, meter panel or supply point that is smaller than the main switch shown in the tenancy switchboard. That means looking only at the internal switchboard may not give a true indication of the available supply capacity for the factory or workshop. Existing site loads, upstream protection, supply limitations, switchboard capacity and simultaneous equipment use can all affect what is actually available. A proper review should consider the equipment list, running loads, startup current, likely simultaneous use and the actual supply arrangement before machinery is selected, installed or connected.
Do you install machinery power?
Workshop Fitouts Victoria helps coordinate machinery power installation as part of workshop fitout projects. Suitable electrical trades are coordinated where required.
Should machinery power be planned before delivery?
Yes. Planning before delivery helps avoid rushed service routes, poor isolator locations and delayed machine setup.
Can you coordinate with machine suppliers?
Yes. Supplier requirements can be considered during the planning and coordination process.
Can three-phase power be included?
Yes. Where equipment requires three-phase power, this can be considered as part of the machinery power planning.
