Poor Design Leads To Big Repair Bills
The photograph above shows a pretty dubious set up for installing a light fitting in the ceiling at the top of a stairwell. While the initial installation is risky, how on earth is anyone supposed to repair that light in years to come?
After these clowns have finished, a builder will fit a handrail around the walkway and there will be no easy way to get to that light even to do something as simple as replace a blown globe. (more…)
Loose Electrical Connections Get Hot, And This Could Be The Result.
Electrical connections can become loose for a variety of reasons. A tightly made connection can become loose over time due to the tiny expansion and contraction that occurs as the cable warms up during use and cools down when not energised. Perhaps the last tradesman to work on the installation didn’t do them up tight enough, or maybe the connecting parts have worn out and don’t make good contact anymore.
Occasionally we find connections that have never been tightened up at all. The wire has been pushed into the terminal and the screw never tightened. This can happen even in new homes and installations. It’s a sign that the tradesman didn’t do a final check by pulling on each wire to make sure it’s solidly connected.
Sometime the connectors or terminals are faulty so even though the screw is done up tight it’s not actually clamping the cable enough. Once again, a simple check by tugging on the wire will alert the tradesman to that type of fault.
Every electrical connection has the potential to get hot. With increased heat comes increased electrical resistance, which in turns causes things to get even hotter. Depending on the location of the connection this heat could potentially start a fire.
Common locations for loose electrical connections include switchboard connections of fuses and circuit breakers, connections to stove elements and hotplates and connections to power points.
The more load being drawn through the loose connection the more likely it is to fail. For example a loose connection to a power point is more likely to be a problem if a heater is plugged in to the heater as compared to a phone charger or some other low wattage device.
Signs To Watch For
Signs that could indicate a loose electrical connection include flickering lights, intermittent power fluctuations, buzzing noises and burning smells. If you do find any of these problems you should have an electrician check it out as soon as possible.

We recently carried out a maintenance check on a solar panel system for a new client and heard a very unfortunate story.
Our client was sold a 5 kw system about 12 months before, by one of those mainland companies that advertise heavily on TV.
The door to door salesman was very helpful and made a phone call direct to head office and managed to get the client a $3,000 discount if he signed up on the day. They also offered him a further $1,000 discount if he would agree to put a promotional sign on his fence.
Even after all these wonderful discounts the client still paid about twice what we would have charged him for the same sized system.
The moral of the story is – don’t buy a solar panel system off the first salesman that knocks on your door. Do a bit of research and get some free local advice and a couple of quotes.
The cheapest system may not turn out to be the best value either, but there is absolutely no need to pay double the going rate to enjoy the benefit of solar panels on your roof.
The door to door salesman also overstated the performance of the system and told the client his panels would never need cleaning. After 12 months the panels were quite dirty and if not cleaned would just further increase the already long payback time on this over-priced system.
Watch this short video to see the problems caused by dirty solar panels.
Every home has unique features that need to be considered when planning a solar panel installation. We believe that a qualified, accredited and experienced installer can design a better solar panel system than a door to door salesman, and possibly at half the price!

This time of year we start to get clients bringing their caravans and campervans in for electrical checks.
Quite often they have purchased the caravan on the mainland and want to change it to Tasmanian registration. Before it can be registered they must have mechanical, gas and electrical checks for safety and compliance.
The electrical requirements for caravans are quite strict and include things like the need for “double pole” power points and light switches, stranded wiring, correct earthing and a safety switch.
Most newer vans have no problem meeting these requirements, however older vans usually need some work done before they can be registered.
A thorough check should take about an hour, if the caravan electrical installation is in good condition, including some paperwork to apply for a compliance sticker, which you need to display to be able to connect to powered sites in Tasmania.
The compliance sticker usually takes a few days to arrive so we also provide a letter of certification that can be taken to the motor registry inspection, so you can complete the registration process without having to wait for the sticker.
Occasionally we see an older van that may have been purchased quite cheaply, but requires a substantial investment to upgrade the electrical system to allow for registration. These old vans rarely turn out to be the bargain they may have first seemed.
If you buy an old van with mainland registration you should be aware that it could cost you several hundred dollars, or even more, for electrical checks and work to get the van in a roadworthy state so it can be registered in Tasmania.
