Low voltage refers to electrical power supplies that produce
relatively low power levels. These systems use special transformers to reduce
the main power supply down to a lower voltage. Low voltage wiring is the wiring
for audio, video, telephone, intercom, data, alarm systems, HVAC, and generally
any wiring for things using less than 24 volts.
One of the drawbacks to lower voltage is that fixtures must
be installed close to the power source or transformer. Low voltage can be used
with small electrical systems only, and may not be appropriate for commercial
or large-scale electrical projects. Electrical
current passing through low-voltage cabling such as telecommunications,
security or video is generally not strong enough to cause a fatal electric
shock. However there still are very real safety risks associated with
low-voltage systems.
Low-voltage can cause unsettling shocks, especially in an
unsafe environment, such as ungrounded or standing in a wet area. While it’s
unlikely that such shocks will cause serious injury by themselves, they
certainly could literally knock someone off balance, which could be a safety
risk if they were standing on a ladder. With low-voltage systems, it’s easy for
people to have a sense of complacency that can build a false sense of security.
