Drive through Warilla, Barrack Heights, Berkeley, Lake Heights or Port Kembla and you will pass street after street of homes built in the post-war decades. Many are solid, well loved houses. But a lot of them still have their original meter box, and decades of coastal weather and add-on electrical work can leave it in poor shape.

Customers have told us we found fire hazards in their meter box while we were there for a different job. It happens more than you might think, which is why we look at the whole box whenever the door is open.

Common hazards we find

Asbestos backing panels

Meter boards installed before the late 1980s were often made from a fibrous material that may contain asbestos. Undamaged, it is generally considered low risk. Drilling, cutting or breaking it releases fibres. If your panel is cracked, crumbling or has been drilled repeatedly, treat it with care and get advice. Do not try to remove or repair it yourself.

Corrosion from salt air

Homes close to the water at Windang, Primbee, Barrack Point and Shellharbour sit in salty air every day. Over years, it corrodes terminals, screws and enclosures. Corroded connections can work loose and heat up.

Water inside the box

A meter box door that no longer seals, a missing grommet or a crack in the enclosure lets rain in. Water near live terminals is a serious hazard and can also cause safety switches to trip.

Loose or overheated connections

Look for brown or black discolouration, melted plastic or a burning smell. These are signs of heat from loose connections or overloaded circuits.

DIY and amateur additions

Over the life of a house, it is common to find extra cables tapped in, mismatched fuse wire, or circuits added without proper protection. These are often invisible until someone looks behind the cover.

Pests

Spiders, ants and the odd mouse like the warmth of a meter box. Nests and droppings can cause tracking and corrosion over time.

What you can safely check

Open the door and look without touching anything inside
Check the door closes and seals properly
Look for rust, water stains, cracks or scorching
Notice any smell of burning or buzzing sounds
Take a photo to send to an electrician

Why these problems stay hidden

Most meter box hazards develop slowly. A terminal corrodes a little more each winter, a crack in the enclosure widens, a connection loosens with years of heating and cooling. Nothing changes from one day to the next, so it is easy to assume all is well. That is why a fresh set of eyes, with the cover off and the right test gear, often finds something the household has never noticed.

Who owns what

The meter itself and some of the incoming service equipment belong to the network or the metering provider. The switchboard, circuit protection and wiring from the board into the house are the homeowner's responsibility. A licensed electrician can tell you which parts need attention and arrange anything that involves the network.

Fixing the problem

Depending on what we find, the fix might be a repair, a new enclosure, or a full switchboard upgrade with modern breakers and safety switches. Where an asbestos backing panel is involved, the work is planned so the panel is handled safely and appropriately. We explain the options in plain language so you can decide.
