DOE-HDBK-1092-2004
Volatile flammable liquid--A flammable liquid having a flash point below 38 degrees C (100
degrees F) or whose temperature is above its flash point, or a Class 11 combustible liquid
having a vapor pressure not exceeding 40 psia (276 kPa) at 38 deg. C (100 deg. F) whose
temperature is above its flash point.
Voltage--(Of a circuit.) The greatest root--mean--square (effective) difference of potential
between any two conductors of the circuit concerned.
Voltage, nominal--A nominal value assigned to a circuit or system for the purpose of
conveniently designating its voltage class (as 120/240,480Y/277, 600, etc.). The actual voltage
at which a circuit operates can vary from the nominal within a range that permits satisfactory
operation of equipment.
Voltage to ground--For grounded circuits, the voltage between the given conductor and that
point or conductor of the circuit that is grounded; for ungrounded circuits, the greatest voltage
between the given conductor and any other conductor of the circuit.
Watertight--So constructed that moisture will not enter the enclosure.
Weatherproof--So constructed or protected that exposure to the weather will not interfere with
successful operation. Rainproof, raintight, or watertight equipment can fulfill the requirements for
weatherproof where varying weather conditions other than wetness, such as snow, ice, dust, or
temperature extremes, are not a factor.
Wet location--See "Location."
DEFINITIONS APPLICABLE TO 29 CFR 1926 SUBPART V
Alive or live (energized)--The term means electrically connected to a source of potential
difference, or electrically charged so as to have a potential significantly different from that of the
earth in the vicinity. The term "live" is sometimes used in place of the term "current--carrying,"
where the intent is clear, to avoid repetition of the longer term.
Automatic circuit recloser--The term means a self--controlled device for automatically
interrupting and reclosing an alternating current circuit with a predetermined sequence of
opening and reclosing followed by resetting, hold closed, or lockout operation.
Barrier--The term means a physical obstruction which is intended to prevent contact with
energized lines or equipment.
Barricade--The term means a physical obstruction such as tapes, screens, or cones intended
to warn and limit access to a hazardous area.
Bond--The term means an electrical connection from one conductive element to another for the
purpose of minimizing potential differences or providing suitable conductivity for fault current or
for mitigation of leakage current and electrolytic action.
Bushing--The term means an insulating structure including a through conductor, or providing a
passageway for such a conductor, with provision for mounting on a barrier, conducting or
otherwise, for the purpose of insulating the conductor from the barrier and conducting current
from one side of the barrier to the other.
