raceway connections. Do not use isolating bushings to interrupt
a metallic raceway run.
A separate isolated ground for the SPD is NOT recommended.
Proper equipment connections to grounding system and
ground grid continuity should be verified via inspections and
testing on a regular basis as part of a comprehensive electrical
maintenance program.
On 4-Wire Power Systems, neutral to ground bonding (Main
Bonding Jumper) must be installed per the NEC ® . Failure to
do so WILL damage SPDs.
UL 1283 required language concerning the installation
of EMI Filters
a) An insulated grounding conductor that is identical in
size and insulation material and thickness to the grounded
and ungrounded circuit supply conductors, except that
it is green with or without one or more yellow stripes,
is to be installed as part of the circuit that supplies the
filter. Reference should be made to Table 250-122 of the
National Electrical Code regarding the appropriate size of
the grounding conductor.
fail SPDs. For this reason, the NEC ® Article 285 has placed
SPD restrictions on ungrounded systems. As generalizations,
SPDs for ungrounded systems can be installed on grounded
systems with a clamping performance penalty. However, SPDs
for grounded systems installed on ungrounded systems are
almost certainly destined for premature failure. Call APT Tech
Support at (800) 237-4567 for further information.
System Grounding
An equipment grounding conductor must be used on all
electrical circuits connected to the SPD.
For the best performance, use a single point ground system
where the service entrance grounding electrode system is
connected to and bonded to all other available electrodes,
building steel, metal water pipes, driven rods, etc. (for reference
see: IEEE Std 142-2007).
For sensitive electronics and computer systems, we
recommend that the ground impedance measurement be
as low as possible. When metallic raceway is used as an
additional grounding conductor, an insulated grounding
conductor should be run inside the raceway and sized per the
NEC ® . Adequate electrical continuity must be maintained at all
