Getting electrical work done

 

Doing your own electrical work

 

As a member of the public, the law allows you to carry out some of your own electrical work.  However, Energy Safety does not recommend that you do any of your own electrical work unless you have the necessary skills and knowledge.  If you do want to do some of your own electrical work it is important that you read the following information carefully.

Never do any electrical work unless you are sure you have the skills and knowledge to do the job safely and legally.  Accidents, and sometimes fatalities, can occur because people do not know what they are doing.  Electrical work can be unsafe and illegal if it’s not done properly.

Energy Safety recommends that if you are in any doubt about doing any electrical work in your home you must use a licensed worker.

The following information is intended only as a guide and provides information on the minimum legal safety requirements for doing your own electrical work safely and legally.  Neither this information nor the Electrical Codes of Practice are do-it yourself guides or manuals.  Knowledge and skills are essential.

 

Before getting started

Before you do any work, make sure that:

  • You have the necessary knowledge and skills.
  • The power is turned off.
  • You are nowhere where conductors or terminals are live or could become live.

 

For more detail on how you can go about doing your own electrical work safely and legally, please see the:

  • Electricity Act 1992 section 79 defines who exactly can do electrical work listed in regulation 64 of the Electricity Safety Regulations 2010.
  • NZECP 50: 2004 – New Zealand Electrical Code of Practice for Repair and Maintenance of Domestic Electrical Appliances by the Owner of the Appliance.
  • Electricity Act 1992 Section 80 defines who exactly can do electrical work listed in regulation 79 of the Electricity Safety Regulations 2010

You can repair an appliance, but...

  • You, or a close relative, must own it,
  • It must be for use by you or a close relative,
  • It must not be for commercial or industrial use,
  • The work is carried out in accordance with the requirements of ECP 50.

 

Remember

  • Before you start work, make sure that the appliance is unplugged from the electricity supply.  It is dangerous to work on it if it is connected. 
  • If the appliance is permanently connected to an electricity supply, ensure that the mains power is switched off before commencing work.

 

What are the main electrical repairs you can do yourself at your home?

For a full list of the electrical repairs you can do on your home, please refer to Regulation 64 of the Electricity Safety Regulations 2010.

Doing your own wiring

When doing work on wiring in your home, you must:

  • Make sure that the power is switched off before you start.
  • Ensure that you do not work in any enclosure where conductors or terminals are live or could become live.
  • Ensure that if you install, extend or alter cables, you do not connect your work to the electricity supply yourself.  The finished job must be checked and tested by a licensed electrical inspector.  If it complies with safety requirements, the inspector will connect it, test it, and issue you with a Certificate of Compliance.
  • Never do any work on a switchboard apart from replacing fuse wire or fuse cartridges.

 

Important

  • Employers, employees, landlords, tenants and school staff (including caretakers) cannot carry out electrical work in their work place or any rented property unless they are registered electrical workers and hold current practising licences.

 

What if something goes wrong?

If you are unsure about anything or think that you might have made a mistake, make sure that the main switch is turned off, and call a licensed electrician to check your work and correct it if necessary.  If you do work that is unsafe you could seriously injure yourself or a member of your family and you could be prosecuted.

To check if your electrician is licensed visit the Electrical Workers' Register.
