Voltage Ratings and Power Source Configurations
Before making connections to the unit, verify that the unit model number and nameplate voltage
rating are appropriate for connection to the intended power source. See the chart for voltage rating
applications with typical power source configurations.
Wire Connections
With parallel connection, the size of the wiring to the SPD unit is independent of the protected circuit’s
ampacity. NEC®Article 285-21(B) requires surge suppressor connecting conductors to be at least #14
copper or #12 aluminum. To reduce the wiring impedance to surge currents, it is recommended that
the phase, neutral (if required), and ground conductors are twisted together and routed in the same
raceway (conduit). Avoid any sharp bends in the conductors.
Overcurrent Protection
The SPD unit conducts practically no current under normal operation and only conducts very short
duration transient surge currents.
NEC®Considerations
The following is from the National Electric Code 2017 Edition.
NEC®285.21 Connection.
NEC®285.24 Type 2 SPDs. Type 2 SPDs shall be installed in accordance with 285.24(A) through (C).
A. Service-Supplied Building or Structure. Type 2 SPDs shall be connected anywhere on the
load side of a service disconnect overcurrent device required in 230.91, unless installed in
accordance with 230.82(8).
B. Feeder-Supplied Building or Structure. Type 2 SPDs shall be connected at the building or
structure anywhere on the load side of the first overcurrent device at the building or structure.
C. Separately Derived System. The SPD shall be connected on the load side of the first overcurrent
device in a separately derived system.

Voltage Protection Ratings
To obtain the voltage protection ratings (VPRs), as obtained by Underwriters Laboratory, Incorporated,
in accordance with the Standard for Safety, Surge Protective Devices (SPDs), Standard 1449, Fourth
Edition, marked on this product, the wire size listed for each product must be utilized to connect the
unit to your facilities’ power grid. Connections made with conductors other than the wire size listed
may result in dierent VPRs.
Circuit Ampacity Limitations
Representative samples of these products have been investigated by Underwriters Laboratories,
Incorporated to withstand, without exposing live circuits or components at system voltages and fault
currents up to 200,000 AIC, as described in the Standard for Safety, Surge Protective Devices (SPDs),
Standard 1449, Fourth Edition.
System Grounding and Bonding
The performance and safety of any SPD system is dependent on proper grounding and bonding.
Grounding is required for safety. Correct implementation also enhances equipment performance.
Incorrect grounding can reduce or impede the SPD’s operation. All electrical circuits to the SPD must
include an equipment- grounding conductor as required by the NEC and local codes.
An insulated grounding conductor is required in addition to any metallic raceway, which may be used
as a grounding conductor. For parallel-connected SPDs, the grounding conductor should be the same
wire size as the associated power conductors.
UNGROUNDED POWER SYSTEMS ARE INHERENTLY UNSTABLE AND CAN PRODUCE
EXCESSIVELY HIGH LINE-TO-GROUND VOLTAGES DURING CERTAIN FAULT CONDITIONS.
DURING THESE FAULT CONDITIONS ANY ELECTRICAL EQUIPMENT, INCLUDING AN SPD,
MAY BE SUBJECTED TO VOLTAGES WHICH EXCEED THEIR DESIGNED RATINGS. THIS
INFORMATION IS BEING PROVIDED TO THE USER SO THAT AN INFORMED DECISION CAN BE
MADE BEFORE INSTALLING ANY ELECTRICAL EQUIPMENT ON AN UNGROUNDED POWER
SYSTEM. CONTACT FACTORY FOR UNGROUNDED APPLICATIONS.
