Domestic House Wiring
From general wiring, adding a power point or light and light switch to full rewires. Our electrical contractors in Adelaide will provide new house wiring and rewiring for existing.
If you’re viewing a house – or maybe have already moved in – what basic checks can you make to find out if the electrics are faulty? As a rule, only testing can tell you that. But there are warning signs that you can look for: Obvious signs of damage to socket-outlets, switches, and lights.
Signs of overheating at socket-outlets.
- How many socket-outlets are there in each room? If there are only one or two, or they are single sockets. It could be an indication that the installation may be quite old.
- The use of extension leads and socket outlet adaptors.
- Round light switches and braided flex hanging from ceiling roses to light fittings, black switches and sockets mounted in skirting boards may require replacing.
- Check the fuse box – just because it looks new doesn’t mean it is – it may have had just a fuse box change, so check the rest of the installation as well.
- Has it got rewirable fuses? These have not been installed in new installations for many years.
- If the fuse box has a wooden back, cast iron switches, or a haphazard mixture of fuses it is likely hat it dates back to before the 1960s and will need to be replaced.
- Switches and plugs not flushed in properly with live parts showing
- Chases not cut deep enough so cable protrudes above plaster
- Holes left in accessories or the fuse box
- Cable sheaths not entering completely into accessories
- Labels omitted on fuse box
- Fuse box not marked up to identify circuits
- Down lights not fitted with fire hoods (if required)
- Cables for outside lights or to a shed not suitable for the environmental conditions encountered
- Additional sockets and lights installed without additional protection of a residual current device (RCD) provided
- Accessories not suitable for the location where they are installed i.e. outside or above a bath or shower or in a swimming pool
- Incorrect protective device fitted
- Connector blocks used but not put in an enclosure, thus exposing live parts
Do not ever use an electrician if they for some reason state that they do not issue certificates upon completion of the work. Usually they do not issue the certificates because they do not test their work and if it’s not tested you do not know that it’s safe.
This is a difficult question to give an overall answer to as each installation would need to be assessed individually. However, the following factors all contribute:
- Any electrical installation is as old as the oldest component in it, which could be cables, socket-outlets, switches; lights, fuse box and any other item of current using equipment
- If an inspection report identifies many departures to the existing installation
- If you require a considerable amount of additional works such as lights and socket-outlets, it may be more cost effective to rewire the complete installation
