Choosing The Right Fuse

A fuse is fitted to cut off electricity flow to your equipment if there is a mains problem, before damage is done to either the appliance or the surrounding area. If the fuse is too large, the appliance will be damaged before the fuse blows. If the fuse is too small, it may cut off the electricity supply unnecessarily.

To find out how many amps the fuse for your appliance needs to be, you can divide the rated wattage by the voltage.

For example: A DVD player may require 300 Watts at 240 Volts AC (Alternating Current). (300 divided by 240) = 1.25

So the DVD player should have a 2-amp fuse. Usually, a 3- or 4-amp fuse is fitted; this is fine, but the lower the amp rating of the fuse is, the safer the item will be as the fuse will blow more quickly in the event of a fault. Replacing a blown fuse is much cheaper than repairing your expensive equipment.

About Energy-Saving Bulbs

You may be scared off at first by the higher cost of energy-saving bulbs, but they are actually a good investment. They will save you money and energy in the long run. Take a look at the facts. Energy saving bulbs are better than regular bulbs because they:

  • Save electricity and energy
  • Are flicker-free
  • Last 8 to 14 times longer than regular bulbs
  • Are available in "daylight", "cool white" and "warm white" varieties.

With just a few watts (electrical power), energy-saving bulbs can provide the same luminance as a regular bulb of a much higher wattage. A regular bulb could therefore be a bigger drain for your electricity bill. The table below shows how much electricity you can save with an energy-saving bulb:

Regular (Incandescent) Bulbs (Watts) Energy Saving Bulbs (Watts) Here's How Much Electricity You Save
25 5 20W
40 7 33W
60 11 49W
75 15 60W
100 20 80W
120 23 97W
