Imagine that your home fuses of 20 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 one hand to the other in "dry" condition could well
over 100,000 Ohm.
If you are playing on stage your body is perspiring extensively and your
body resistance is lowered by more than 50%. This is a situation in which
current can easily flow.
Current will flow when there is a difference in ground potential between
equipment on stage and in the P.A. system. Please do check if there is any
potential between the housing of the mikes and the guitarsynth amps, which
will be linked by your body on stage. Imagine, a guitar in your hand and your
lips close to the mike! A ground potential difference of above 10 volts is not
unusual, in improperly wired buildings it can possibly be as high as 240 volts.
Allthough removing the ground wire sometimes cures a system hum, it will
create a very hazardeous situation for the performing musician.
Always earth all your equipment by the grounding pin in your mains plug.
Hum loops should be only cured by proper wiring and isolation input/output
transformers.
Replace fuses always 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 carefull 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
inmediately
Always keep the above mentioned
information in mind when using electrically
powered equipment.
