EFFECTS
OF LIGHTNING
Lightning is a natural phenomenon of overwhelming
force that represents the most difficult circumstance
faced by a power protection product. The degree of
protection any product can offer depends on the
intensity of the strike. If lightning strikes a distant
power line and causes a relatively small disturbance to
reach your location, the spike suppressors in the
entire Metered Six Line will absorb the excess voltage
invisibly and harmlessly. However, if lightning strikes
the actual building where one of these units is installed
(or somewhere very nearby), some damage may be
unavoidable due to the extremely high voltage and
current present. If this does occur, the damage is
usually limited to the Metered Six unit itself, and will
affect only certain spike suppression components
(called varistors or MOV’s). In this “suicide” mode, the
unit may sustain minor damage but generally will
protect all equipment plugged into it from much more
serious and costly damage as long as that equipment
is properly grounded. Proper grounding requires the
use of three-prong AC cords, and that the building’s
outlets are actually grounded to earth as specified by
the National Electrical Code.
Any Metered Six unit known to have taken a direct
lightning hit should be checked by a qualified technician
or the Furman factory to determine whether the MOV’s
need replacement. (If the PROTECTION OK indicator is
not lit, there is definitely some damage. Some spike
suppression capability may still be available by MOV
Bank #2, but there is no guarantee of this.)
For optimum protection, you should not rely exclusively
on any Power Conditioner, Regulator, or Surge
Suppression product as the sole means of protection
against a direct lightning hit. The first line of defense
against lightning should be a lightning arrestor installed
on your building’s electrical service entrance. If your
building does not have one, contact your local power
company or a contractor to have one installed.
