Three-phase mains upgrade
Single phase to three phase, for homes drawing more than the mains can supply.
Kew is about three kilometres north of our Hawthorn East workshop, usually ten to fifteen minutes depending on the Junction.
Kew is a big-block suburb, and block size is what drives the electrical work here. Long driveways, outbuildings, pools and rear studios mean distance between the switchboard and the load, and distance is the enemy of a supply that was sized a long time ago.
The grand houses through Studley Park and around Sackville Street have usually been extended several times, and each extension tended to add a small board rather than rethink the main one. The result is two or three boards around the property, no schedule for any of them, and nobody certain what feeds what. Documenting that is a half day that repays itself on the next job.
A run from the house to a pool plant room or a rear studio can easily exceed forty metres on a Kew block. If that cable was sized for the load of the day and the load has since grown, voltage drop follows. Pumps run hot, lights dim when plant cycles, and equipment fails earlier than it should. It reads as an equipment problem and it is a cable problem.
Many larger homes here already have three-phase for air conditioning, pool plant and a workshop. What they frequently do not have is balance. Circuits were added one at a time onto whichever phase had a spare way, so one phase carries most of the house. The symptoms are voltage drop and protection tripping well inside its rating. Measuring it takes an hour and often avoids a supply upgrade nobody needed.
The streets falling away toward the Yarra have a mix of overhead and underground supply, and where a property has an underground service the point of attachment and the pit are the first things to establish before any mains work. It changes both the method and the distributor paperwork.
Closer to the Junction there are period homes with original fabric worth protecting. Rewiring these is about route planning as much as cable: roof and subfloor rather than chased walls, so cornices and plasterwork survive the job.
We are three kilometres away in Hawthorn East. Kew is a ten to fifteen minute run outside peak, longer if the Junction is backed up. Morning faults are normally attended the same day, and for genuine emergencies we aim to be on site within two hours with the phone answered 24 hours.
We also cover Hawthorn, Hawthorn East, Camberwell.
Single phase to three phase, for homes drawing more than the mains can supply.
Ceramic fuses replaced with circuit breakers and safety switches, with capacity left for what you add next.
Period homes with cloth or rubber-insulated wiring brought up to AS/NZS 3000, in stages if needed.
A written check of the board, the wiring and the safety switches, for a purchase, a rental or peace of mind.
Downlights, pendants and outdoor lighting, replaced or run from scratch.
About ten to fifteen minutes from Hawthorn East outside peak hour. The Junction can add to that at the wrong time of day. Same-day attendance is normal for faults reported in the morning.
It often is, and on a Kew block the usual cause is voltage drop on a long undersized submain from the house to the plant room. The pump runs low and hot, and dies early. Replacing the pump again without measuring the supply tends to buy you the same outcome.
Possibly not. On a lot of Kew properties the supply is adequate and the load is simply sitting unevenly across the three phases. We measure the imbalance and the maximum demand before recommending an upgrade, because rebalancing is usually a day's work and much cheaper.
Yes, and it is worth doing before you need it. We identify and test every circuit, label them legibly, and leave a schedule on each board with a copy for you. On a large property that document is the difference between a half hour job and a half day one.
In most cases yes. The work is planned through roof and subfloor space rather than by chasing walls, which is slower but keeps cornices and original plaster intact. We walk the route with you before starting so you know exactly where access is needed.
Fastest way to get an answer is the phone. It is answered 24 hours a day, seven days.
