High voltage safety test
Experienced electricians, at first contact, always assume that hazardous voltages
may exist in any wiring system. A safety check using a known, reliable voltage
measurement or detection device should be made immediately before starting work
and when work resumes.
Lightning and high-voltage danger
Most electrical injuries involving low-voltage wiring result from sudden, unexpected
high voltages on normally low voltage wiring. Low-voltage wiring can carry
hazardous high voltages under unsafe conditions. Never install or connect wiring or
equipment during electrical storms. Improperly protected wiring can carry a fatal
lightning surge for many miles. All outdoor wiring must be equipped with properly
grounded and listed signal circuit protectors, which must be installed in compliance
with local, applicable codes. Never install wiring or equipment while standing in
water.
Wiring and equipment separations
All wiring and controllers must be installed to minimize the possibility of accidental
contact with other potentially hazardous and disruptive power and lighting wiring.
Never place 24VAC or communications wiring near other bare power wires, lightning
rods, antennas, transformers, or steam or hot water pipes. Never place wire in any
conduit, box, channel, duct or other enclosure containing power or lighting circuits
of any type. Always provide adequate separation of communications wiring and
other electrical wiring according to code. Keep wiring and controllers at least six feet
from large inductive loads (power distribution panels, lighting ballasts, motors, etc.).
Failure to follow these guidelines can introduce electrical interference and cause the
system to operate erratically.
