2. Life safety hazards
Whywe do it

3. Your facility is more likely
to burn down because of an
electrical hazard
than from any other cause.”
― Facility Manager’s Alert, Progressive Business Publications

4. Nearly two-thirds of
all electrical
distribution fire
losses could have been
prevented.―National Fire Protection Agency (NFPA)
Preventable
losses

5. A well-administered electrical
preventative maintenance program
will reduce accidents, save lives,
minimize costly breakdowns and
unplanned shutdowns of equipment.”
―NFPA 70B

6. Power quality
Whywe do it

7. Overheating caused by
harmonic current is a
threat to public safety
because of its potential to
cause fires.”
―NFPA Journal, National Fire Protection Association

8. • Harmonic Distortion
• Voltage Transients
• Voltage Sags and/or Surges
• Grounding
• Disruption of Power
• Radio Frequency Interference (RFI)
• Electro-Magnetic Interference (EMI)
―Edison Electric Institute
Power quality problems

9. Causes of power quality problems
• Natural Phenomena
• Utility Operations
• Customer Operations
• Neighboring Customers

80%
―Edison Electric Institute

10. Utility costs
Whywe do it

11. Improper torquing
There are an average
of 16 hot spots in
an average size
commercial property.
―Edison Electric Institute

12. Improper torquing
A high percentage of
these are loose
connections.

13. Improper torquing
• However, a high
percentage of these are
over-tightened
connections!
• Over-tightening leads
to more hot spots!
―Maintenance Technology
Magazine, February, 1998
ELECTRICAL CONNECTIONS CAN BE
DEFORMED BY OVERTIGHTENING
CORRECTLY
TIGHTENED
OVER-TIGHTENED

14. Power factor correction system
capacitor
• Older capacitors rarely
still work as designed.
• Many electric utility
companies penalize
customers for
inefficient use of power
by charging a “power
factor penalty.”

15. 5% Voltage Imbalance =
>125% power consumption
in motors
―Electrical Power Research Institute (ERPI)

16. A 5% phase imbalance can
cut the life of a motor by
one-half and increase
operating costs by $1,200
per year for a 100 hp motor.”
―Electrical Power Research Institute (ERPI)

17. Business
interruptions
Whywe do it

18. Without preventative
maintenance, the
failure rate of electrical
system components is
three times higher.”―Institute of Electrical and Electronic Engineers (IEEE)

19. • What you see on the
outside of electrical
equipment is also on
the inside of the
equipment.
• When was the last
time your electrical
equipment was opened
and cleaned?
Dust can be a conductor!

21. Regular preventive
maintenance is the
best protection
you have against sudden
and costly power outages.”
―Plant Services Magazine

22. Without an EPM (electrical
preventive maintenance)
program, management assumes
a much greater risk of serious
electrical failure and its
consequences.
―NFPA 70B

23. Asset management
Whywe do it

24. Asset management
Your electrical
distribution
system averages
10 –15%
of facility
construction cost

25. Asset management
Proactive care extends the
lift of the equipment and
delays costly capital
expenditures!

26. Insurance certification
Whywe do it

27. Insurance certification
Equipment ranked by
frequency of loss claims:
1. Electrical equipment (all types)
2. Air conditioning and refrigeration
3. Boilers, pressure vessels and piping
4. Machinery (all types)
5. Computer equipment
6. Motors (including air conditioning)
7. Pumps
8. Telecommunications
Accounts for the most common equipment breakdowns and
includes exposures found in every business and organization.Whistle Stop Newsletter, Published by the
Hartford Steam Boiler Inspection and
Insurance Co., Hartford, CT, June 2003;
HSB Is a leading global equipment
breakdown insurer and reinsurer.

28. Insurance certification
• Many insurance
companies and
certifying entities
require proactive
electrical preventive
maintenance.
• We will provide you
with the necessary
compliance certificates.

29. Manufacturers’
recommendations
Whywe do it

30. “Periodic maintenance on the
switchboard includes cleaning,
lubrication and exercising component
parts. The interval between
maintenance checks can vary
depending upon the amount of usage
and environmental conditions of each
installation. The maximum
recommended inspection
interval is one year. This
definition for periodic
maintenance applies
throughout this manual
unless otherwise noted.”
