Because the “blowing” of a fuse results from the overloading of an electrical circuit, many people think that the fuse box is a dangerous area to approach, as it controls the flow of so much electricity. Nothing could be further from the truth. Of course, it is always advisable to approach electrical apparatus with caution; but there should be no fear whatsoever attached to the common chore of changing a burnt fuse.

As far as fuses are concerned, the cardinal rule is “be prepared.” That is to say, you should make a list of all the different types and sizes of fuses in your fuse box, and make sure you have three or four of each on hand at all times. Because if one “blows” on Sunday, you’ll be sitting in the dark till Monday.

Now, if you really want to be secure when working around your fuse box, take this advice, and make the following chart:

1. Make a diagram of your fuse or circuit breaker box
2. Number each fuse or circuit breaker, both on the chart and beside each in the box, making sure that your numbers correspond exactly with one another.
3. Turn on all the lights in your apartment or house.
4. Now, one at a time, unscrew each fuse or trip each circuit breaker and see which lights go off.
5. Mark down beside each fuse or circuit breaker in your chart the area of the house or apartment each controls.
6. Once you have completed this, tape your chart beside the box in plain site.
7. From then on, if the power fails in your bedroom, you’ll know exactly which fuse or circuit breaker has disconnected and must be corrected by consultining the chart.

Procedure for Re-Setting a Fuse or Circuit Breaker

1. When a current fails in a section of your house, consult the chart prepared above.
2. While standing on wooden platform (it is recommended to stand on something that doesn’t conduct electricity), unscrew that fuse and examine with a flashlight. You will see a deep, gray “cloud” on the surface of the fuse.
3. Replace fuse with one of identical amperage. Never, never, under any circumstances, replace one fuse with another of higher amperage. It is the greatest fire hazard.
4. If a circuit-breaker needs to be re-set, trip it to the “off” position and then to the “on” position. Power should be restored.
5. If fuses and circuit breakers repeatedly disconnect, consult a professional electrician.
