Tips for the placement of electrical sockets

On 01, Feb 2016 | One Comment | In Technical tips | By Sem Etis

Putting an electrical socket in the right place seems a simple task, but it is not. There many things to keep in mind, such as the type of socket housings, the height, the existing wiring, etc. Below you can find a few tips to help you get the placement of your electrical socket correct.

Electric sockets in walls

Are you going out to buy built-in boxes for your electrical sockets? Then take the type of mounting into account. We have built-in boxes for solid walls and cavity walls. Furthermore, there are special built-in boxes for cookers.

Furthermore, you should consider the height. Built-in electrical sockets are usually placed ± 25 cm from the finished floor (from the plinth).

Wall socket height

If you plan to cut your own pipes for the electrical sockets, don’t forget the construction of the floor. For example, with 10 cm of floor insulation and 7 cm of screed on top of the concrete slab, you will need to install the recessed boxes at a height of 42 cm (or 10 cm + 7 cm + 25 cm).

Electrical sockets in the floor

It can sometimes be useful to place an electrical socket in the floor, for example under a desk or cubicles. Special built-in boxes have been developed for this. These can also be found in our webshop . You can see step-by-step instructions for installation of such an electrical floor socket in the video below.

Outdoor electrical sockets

An electrical socket in the garden always comes in handy. You can plug in many types of devices, such as a radio, garden lamp, Christmas decorations, etc. Special waterproof electrical sockets are available for outdoor use. This means the socket is protected from rain and other bad weather. In the past, they were only available in a grey colour; nowadays they are also available in white and black. You also have a choice between built-in and surface-mounted sockets.

Safety distances in the bathroom

If you want electricity and lights in the bathroom, a number of virtual safety zones must be established. This also applies to electrical sockets. An electrical socket next to the bath is very dangerous.

The Belgian General Regulations for Electrical Installations (AREI) require a minimum distance of 60 cm between the electrical sockets and the bath, the shower and the sink. In addition this circuit must be protected by a 30mA differential circuit breaker.

The number of electrical sockets

Make sure there are plenty of electrical sockets (especially in the case of a new construction). The additional cost of a socket will be negligible to the frustration you will feel later if you find you have too few. So try to estimate the number and type of electrical devices you will use in the room ahead of time. A few tips:

In the kitchen:

  • Mobile devices, such as a coffee maker, kettle, blender, radio, phone charger, etc.
  • Fixed appliances, such as a dishwasher, microwave oven, refrigerator, etc.

In the living room:

  • A TV set
  • DVD or Blu-ray player
  • Stereo equipment
  • Games console
  • Digital TV box
  • Table lamps/floor lamps

In the bedroom:

  • Table lamps on the bedside table
  • An electrically adjustable bed base
  • Place for charging a smartphone/tablet on both sides

In an office:

  • Computer/laptop
  • VDU display
  • Printer
  • External hard drive with a separate power supply
  • Desk lamps
  • Speakers with a separate power supply

Furthermore, keep in mind that there may be other applications that require an electrical socket, such as an electrical outlet near the dining room table for a gourmet or fondue set, or easily accessible electrical outlets for the vacuum cleaner, etc.

Number of electrical sockets

Electrical sockets: better to have one too many than one too few.

Horizontal or vertical

Double (or triple) electrical sockets can be mounted horizontally or vertically. This is a personal choice. Take into account the fact that some plugs may block sockets underneath if they have been mounted vertically.

Also, don’t forget: for horizontal electrical sockets, leave the partitions attached. For vertical mounting, these must be removed.

8 outlets per circuit

Each circuit is limited to 8 outlets. A double electrical socket counts as one outlet. Major consumers of electricity, such as an electric cooker are best placed on their own, separate circuit.

The wiring

For wiring a standard electrical socket, use a 3G 2.5 mm² cable. Keep in mind though, some appliances, such as an induction hob, require a different kind of cable.

More than electrical sockets

In addition to the standard electrical sockets, other connection points are also required in a home. For example, a TV or internet connection. Make sure you don’t forget about these.
