Matters three and 5: Further Low Voltage and Low Voltage Hazards and
Dangers
Quick reply questions (1 mark per written half or as proven)
Further low voltage is outlined as no more than 50Vac or 120Vdc. Low voltage is outlined as
being between 50Vac and 1000Vac or between 120Vdc and 1500Vdc.
Be very cautious of those names which could possibly be deceptive to an individual who has not had
coaching within the Electrotechnology subject. Low voltage is deadly. Further low voltage is also
deadly in the precise atmosphere akin to excessive humidity, dampness, salt water, physique salts from
perspiration and many others. This can be a crucial space for security threat administration, and you could do
all of the studying and present a excessive understanding of the hazards and hazards when working with
electrical circuits.
Learn the next code of follow as your life and that of others round you is just not
value taking dangers with electrical energy. Simply copy and paste in GOOGLE.
