TYPICAL EMERGENCY GENERATOR INSTALLATION PRACTICES
FOR “OPEN” (NON-SELF ENCLOSED) GENERATOR
A standby emergency power systems will give years
of dependable service when installed properly.
Incorrect installations can cause continuing service
problems and may result in harm to humans. It is the
responsibility of the owner or operator to know and
understand the correct installation methods. It is of
particular importance to know safe methods
especially, when installing an open generator inside
a building. Following is a partial list of
1) The generator building must not be inhabited by
humans or animals.
2) The building floor must be cement and capable of
supporting generator weight, the running vibration,
and any generator associated equipment. If in doubt,
have the floor load carrying capacity tested by
specialist. A heavy equipment lifting contractor
should be consulted for this task.
3) The generator engine requires a certain amount of
cooling air, which changes with different generator
KW sizes. The CFM cooling air requirement, if
insufficient, will cause early, automatic shutdown of
complete generator set.
4) Generator operating noise is high, so quieting
devices may be desirable: double walled room,
sound deadening materials on wall, etc.
5) Building code and safety requirements for open
gen-set operation within a building are important to
know and compliance to the codes, are essential:
National Electric Code, Articles: 230, 250, 245, 517,
National Fire Protection Association (NFPA)
#37—Stationary Combustion Engines and Gas
#99—Essential Electrical Systems for Health Care
#101-Life Safety Code Number Systems.
#110-1985 Emergency and Standby Power
Local applicable codes (consult local building
inspector or fire department).
6) Generator room size: Room should be dedicated
for only generator use, not for miscellaneous storage,
work area, etc.
7) Specialized controls, transfer switches, and other
generator required equipment may be installed in
generator room, depending on local codes.
