How many power points per room and house?
I often get asked this question; unfortunately there is no exact answer to this. The ideal amount and position of each power point depends on the layout of your house and the circuits involved.
Although it is advisable to install as many power points as possible when building a house, it can become quite an expensive task as building companies are likely to take their margin out of electrical work as well. It is therefore logical to install a basic set with your builder and request additional work to be carried out by a licensed electrician.
Generally, having more than two power points in each room is recommended, giving you the option of moving around furniture and avoiding extension cords / connections across a room. Moreover, connecting too many devices into one power point can cause the GPO to become overloaded, and in worst case scenario lead to a fire.
Internal walls and external walls
When building a home (double-brick built), make sure you position your initial power points on internal walls, as these will be impossible to access later without creating a lot of mess. Power points on external walls can always be added without too much fuss.
Power points in bathrooms, kitchens and other wet areas
Water is an excellent conductor of electricity, so when planning to install additional power outlets in this area, it is inevitable to consult a licensed electrician.
Australian/New Zealand Wiring Rules (AS/NZS 3000:2007) clearly lay out the regulations for installing power points in wet areas and I can advise you based on these rules.
