In many homes, rooms are typically equipped with only a limited number of power outlet points. People tend to think that sockets in one or two corners of each room will suffice and if not, they can always use extension leads to reach other areas in the room. Some architects even advocate limiting the number of power outlets, as they find that the sockets compromise their aesthetic goals.
Unfortunately, power outlets in one or two corners per room will never do.
Yes, you can always use extension leads, but that introduces new problems. For one thing, most people do not like the look of cords lying around. That is why extension cords are more often than not hidden away behind chests or other furniture. This practice almost inevitably results in connections that are difficult to reach. In addition, when an extension cord is lying around, one can easily stumble over it. Some even try covering the cord with a carpet, which is highly unsafe. This can result in broken wires, worn insulation, overheating and ignite fires. Similar overheating problems may arise with long cords that are wound up tightly or bundled to the required length. Then there is the use of extension cords in the bathroom; this is an extremely dangerous practice. Finally, good quality extension leads are not cheap. Extension leads are useful but they must be used correctly and sparingly.
It is far better to think ahead and plan enough power outlets in your home, for example in all four corners of each room. This enables you to neatly integrate the sockets into the design of the room, avoids having cords lying around, and enables occupants to rearrange their interior whenever they feel the need for change.
