Hazardous electrical shock can be avoided by carefully following the above rules.
Voltage and current cause an electrical shock. In practice the higher the voltage the higher the
current will be and the higher the shock. However, there is another thing to consider and that is
resistance. When the resistance in Ohms is high between two poles, the current will be low and
visa versa. All three of these; voltage, current and resistance are important in determining the
effect of an electrical shock.
PLEASE READ THE FOLLOWING INFORMATION VERY CAREFULLY
The severity of a shock is caused by the amount of current flowing through a person.
A person can feel a shock because the muscles in a body respond to electric current. Current
can also be fatal when it causes the chest muscles to contract and stop breathing.
At what potential is current dangerous? Well the first feeling of current is a tingle at 0.001 Amp
of current. The current between 0.1 Amp and 0.2 Amp is fatal.
Imagine that your home fuses of 16 Amp can handle 200 times more current than is necessary
to kill. How does resistance affect the shock a person feels? A typical resistance between your
two hands "dry" condition could be well over 100,000 Ohm. But if your body is transpiring
extensively your body resistance is lowered by more than 50%. This is a situation in which
current can easily flow.
Always earth all your equipment by the grounding pin in your main plug. Proper wiring and
isolation input/output transformers should only cure hum loops.
Always replace fuses with the same type and rating after the equipment has been turned off
and unplugged. If the fuse blows again you have an equipment failure. Do not use it again and
return it to your dealer for repair.
And last but not least be careful not to touch a person being shocked as you, yourself could
also be shocked. Once removed from the shock, have someone send for medical help
immediately!
Always keep the above-mentioned information in
mind when using electrically powered equipment.
