How To Avoid House Fires From Bad Wiring

The Dangers of Faulty Electrical Wiring

There are approximately 4,000 house fires in New Zealand annually. Faulty house wiring and electrical appliances cause many of these fires. It’s estimated that around 80% of these fires could be easily avoided (Cavius, 2017).

There is no doubt that if your home was built 30 or more years ago, you should have the wiring checked by a professional electrician. Thorough electrical checks are especially important when buying a new home. It’s often difficult to establish if there are any electrical faults that will cause problems further down the line if not addressed by a professional electrician.

If your house was built before the 1980’s and hasn’t been rewired, you should almost certainly contact a professional electrician to test your wiring and identify any possible faults. More severe electrical faults that are left unrepaired can cause house fires and even electrocution. Northern Lights have over 20 years’ experience in identifying and fixing all manner of electrical failures. We can also install complete rewiring for homes where needed.

In December 2017 a New Zealand resident Mathew Smith, 26 tragically died cutting an electrical cable on Hamilton camping site. Had the campsite’s electrical cabling had an RCD installed, a relatively cheap device to install, his life would likely have been spared. RCDs only became mandatory for electrical wiring within New Zealand in 2013; the campsite wasn’t at fault with its preexisting wiring. This incident highlights how important this simple piece of equipment is

Northern Lights House Rewiring

Northern Lights always install RCDs when they’re setting up house wiring. RCD stands for Residual Current Device. RCDs work by automatically disconnecting a current in many situations where a person may have otherwise received a fatal electrical shock.

Need more power points? You should never overload your power points with multiple extensions. This is a common cause of electrical house fires. If your house doesn’t have sufficient power points for modern technological needs, then Northern Lights can help. We can add additional power points in strategic locations in your home to meet your contemporary electrical needs and future electricity demands.

If you’re replacing your power points with power points with additional outlets Northern Lights can install a socket outlet RCD, which will protect equipment that’s plugged into the outlets and make the sockets additionally safe. RCDs are a legal requirement for sockets in damp areas like bathrooms but not in all areas of the house. Northern Lights are happy to install them at any power points so that you have additional peace of mind. We believe RCDs should always be installed especially if there are curious young children in your household.

Surge Protection

If your house was built before the 1980’s an additional reason you should consider home rewiring is the installation of surge protection. This will prevent your electrical devices from being ruined by unexpected surges of electrical voltage.

Northern Lights are able to design a full or partial re-wire for your existing home, or review and implement the electrical plans for your home. Failure to plan can ultimately lead to failure: by planning with Northern Lights ahead of time you are able to make the most practical and informed electrical choices and ensure satisfaction throughout the entire process.

At Northern Lights we recognise that there is an overwhelming number of options and that the cost of house rewiring can be unnerving. We aim to alleviate your stress and worries by meeting and discussing all of your available options. We will work with you to provide the optimal solutions to meet your needs.

    I have used Northern Lights' services twice this year to install several self-supplied ceiling fans in my apartment. They were able to easily integrate the controller into my existing gang-plate style, … More and where possible there was minimal access-hole drilling. I was going to ask for the same electrician as the prior install seeing as he already had knowledge of our fit-out, but the team were onto it and already suggesting the very same.
    Ultra-professional and very reasonable rates, especially for accommodating custom components. They'll be on my speed dial for future electrical work!
    Thanks heaps guys!
