force that represents the most difficult circumstance
faced by a power protection product. The degree
of protection a PS-PRO 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
PS-PRO will absorb the excess voltage invisibly
and harmlessly. However, if lightning strikes the
actual building where the PS-PRO is installed (or
somewhere very nearby), some damage may be
unavoidable due to the extremely high voltage
and current present. If this does occur, most likely
damage will be limited to the PS-PRO itself and will
affect only certain spike suppression components
(called varistors or MOV’s.) In this “suicide” mode,
the PS-PRO 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 PS-PRO 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 PS-PRO’s 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 the PS-PRO to protect against a
direct lightning hit. The first line of defense against

the Furman factory to determine whether the MOV’s
