Book a licensed electrician to inspect your single-phase or three-phase commercial switchboard, agree the scope in writing and carry out the customer-side switchboard and circuit work, testing and handover, for shops, offices, restaurants, cafes and warehouses across Sydney.
Blue Link Electrical Services upgrades single-phase and three-phase switchboards for shops, offices, restaurants, cafes and warehouses across Sydney, with an Inner West focus. We inspect the board and the load, agree the scope in writing and carry out the customer-side switchboard and circuit work. Blue Link is not Level 2 accredited: any meter, service mains or network work is Level 2 work, which we source out to accredited partners. NSW licence 332956C, since 2016, fully insured, lifetime warranty on workmanship. Call 0421 772 661.
For a home rather than a business, our switchboard upgrades hub covers residential boards, and a single failed breaker or safety switch is usually a repair rather than an upgrade.
Planning the power interruption is part of the job. On a commercial site that means working out when the power can go off and what happens to the business while it is off. Where possible we look at the site while it is trading, so we can see what runs when, then agree the changeover time with you in advance.
Before the day, you get a plain list of what is expected to lose power: refrigeration, cool rooms, the point-of-sale system, data equipment, alarms and lifts or roller doors if they are on the board. If the main switchroom is shared or locked, we arrange access with the agent, building manager or strata manager first.
Book a site visit. We look at the board, the supply and the equipment, and ask what is planned.
You get the scope and quote in writing, including anything that needs Level 2 work or an approval.
Access, approvals and any Level 2 work by accredited partners are lined up first.
The supply is isolated and proven dead, the old board comes out and the new board goes in.
Circuits are tested, safety switches trip-tested and every circuit labelled.
We walk you through the board and supply the CCEW for the notifiable work.
Combi ovens, commercial dishwashers, refrigeration and compressors can add loads that need to be checked against the existing board and supply.
A board that drops out when the coffee machine, ovens and air conditioning all run together needs testing to establish whether the cause is overload, a fault or phase imbalance.
A change of use can introduce equipment and circuit requirements that need checking against the existing board and supply.
Labels left by previous tenants may no longer match the circuits. The circuit labels need checking before isolation.
Still working out what the upgrade involves? Our planning checklist below covers the records, equipment list, approvals and access questions to sort out before the inspection.
The more you know about the board and the load before we visit, the clearer the written scope. Missing records are common and are not a reason to delay booking the inspection.
Whether the existing board and supply can take the planned load, including new three-phase equipment, is assessed at inspection, not from the list alone. If a supply change turns out to be needed, that meter, service mains or network work is Level 2 work. It is sourced out to accredited Level 2 partners and identified in the written scope. At the inspection, ask what the scope excludes and what isolation the work requires.
If the board is hot, buzzing or smells of burning, don't wait to finish a checklist. Stop using the affected equipment if it is safe to do so and call our 24/7 emergency electrician line. A single faulty breaker, safety switch or connection may need switchboard repairs rather than a full upgrade.
An existing three-phase installation may have uneven loads across the phases. Testing is needed to establish whether tripping is caused by overload, a fault or phase imbalance.
A three-phase upgrade is planned around the equipment. We list what is connected now and what is coming, spread the load across the three phases, fit a three-pole main switch and dedicated three-phase circuits for motors, ovens, compressors and larger air conditioning, and fit RCD or RCBO protection selected for the circuits and applicable requirements. Motor circuits are checked for correct phase rotation before equipment is restarted, and the circuit schedule shows which phase each circuit is on.
If the premises is single-phase now and needs three-phase, the new supply involves your network and Level 2 work on the service mains and meter. That part is sourced out to accredited Level 2 partners. We carry out the customer-side switchboard and circuit work and plan the switchboard work around the required supply work.

Lighting, signage and display fridges, with planned fit-out loads checked against the board and supply.
Comms equipment can be put on its own circuit, so a tripped heater circuit does not also take the network down.
Kitchen loads from ovens, dishwashers, coffee machines and refrigeration checked against the board, with a sensible split of circuits.
Three-phase circuits for compressors, roller doors and machinery, with lighting kept on its own protection.
We upgrade commercial switchboards across Sydney, with an Inner West focus. That includes main-road strip shops, mixed-use buildings with a shop below and apartments above, and warehouse units. Local pages: commercial electrical Marrickville, Petersham, Ashfield and Croydon, plus our electrician pages for Leichhardt, Newtown, Stanmore and Alexandria.
Projects: a three-phase switchboard in Ashfield and a commercial fit-out in Stanmore. In strata and mixed-use buildings, our strata electrician page explains how we work with owners corporations, and agents can see the property manager electrician page. For lighting, circuits and fit-outs beyond the switchboard, see commercial electrical services. If a board fails outright, call the 24/7 emergency electrician line.
Call 0421 772 661 or send an enquiry. We arrange a site visit to inspect the board, the supply and the equipment, then send you the scope and quote in writing before any work is booked.
Yes. We upgrade three-phase switchboards for shops, offices, restaurants, cafes and warehouses, including balancing loads across the phases, three-phase circuits for equipment and RCD or RCBO protection selected for the circuits and applicable requirements.
We carry out the customer-side switchboard and circuit work. Blue Link is not Level 2 accredited, so the network, service mains and meter work for the new supply is Level 2 work that we source out to accredited partners. We plan the switchboard work around the required supply work.
The power has to be off for part of the job. We agree the changeover time with you in advance and tell you which equipment is expected to lose power, so you can plan stock, staff and customers around it.
We upgrade switchboards for shops, offices, restaurants, cafes and warehouses across Sydney, with an Inner West focus.
