2 SPC series catalog number
Each Eaton SPC series unit is identified by a catalog number, see
Table 1
. The number identifies the parameters that make up the
unit .
Table 1. Catalog Numbering System
For example, an SPC unit with a catalog number of
SPC200208Y8P
,
where:
SPC
= SPC series
200
= peak surge current rating (50 kA – 200 kA)
208Y
= voltage code and system configuration
8
= feature option (1 – 8)
P
= enclosure type (Type 4X enclosure)
See
Section 10. Ordering guidelines
for additional surge current kA
ratings, voltage codes and feature options .
3 SPC series product nameplate
Each Eaton SPC series unit has a nameplate affixed to the side of
the unit that identifies the catalog number and operating parameters .
The catalog # consists of letters and numbers which identify the
SPC series, kA rating, voltage code, feature option and type enclo-
sure as shown in Figure 1 .

WARNING
A LICENSED/QUALIFIED ELECTRICIAN MUST COMPLETE ALL
INSTRUCTIONS IN THIS MANUAL IN ACCORDANCE WITH THE NATIONAL
ELECTRIC CODE (NEC), CANADIAN ELECTRICAL CODE (CEC), STATE, AND
LOCAL CODES, OR OTHER APPLICABLE COUNTRY CODES. ALL APPLICABLE
LOCAL ELECTRICAL CODES SUPERSEDE THESE INSTRUCTIONS.
INSTALLING AN SPD THAT IS IMPROPERLY RATED FOR THE ELECTRICAL
SYSTEM VOLTAGE COULD CREATE A POTENTIALLY HAZARDOUS
CONDITION, RESULTING IN INJURY OR EQUIPMENT DAMAGE.
CHECK THE VOLTAGE-RATING LABEL LOCATED ON THE SIDE OF THE SPD
TO VERIFY THAT THE ELECTRICAL SYSTEM’S VOLTAGE AND WIRING
CONFIGURATION ARE THE SAME AS THE SPD.
TO PROVIDE THE BEST PROTECTION FOR SENSITIVE ELECTRICAL
EQUIPMENT THE 10 AWG WIRES SHOULD BE LESS THAN 14” IN LENGTH,
TWISTED TOGETHER AND THEN BOUNDED.
AVOID USING 90° CONDUIT ELBOWS AND KEEP THE CONDUIT RUN AS
SHORT AND STRAIGHT AS POSSIBLE. SEE FIGURES 1 AND 2
WHEN MOUNTING THE SPD OUTDOORS, USE WEATHERPROOF CONDUIT
AND FITTINGS TO MAINTAIN THE ENCLOSURE’S NEMA TYPE 4X RATING.
FOR USE ON CIRCUITS DELIVERING UP TO 5000 RMS AMPS. CONVIENT Á
DES CIRCUITS PRODUCISANT AU PLUS 5000 A EFF.
Before installing an Eaton SPC Series unit:
1 . Verify that the area is clear of any dirt, debris or clutter that may
hamper the installation process .
2 . Verify that there is enough space to install the SPC . See Figures
4 & 5 for dimensions .
3 . Confirm that the system voltage and wiring configuration is
the same as the SPC you are installing . See
Section 5. Wiring
Diagrams.
4 . Check the facility grounding system . All grounding, bonding, and
earthing must meet the NEC, CEC and any other national, state
and local electrical codes .
5 . An insulated grounding conductor that is identical in size and
insulation material and thickness to the grounded and unground-
ed circuit supply conductors, except that it is green with or with-
out one or more yellow stripes, is to be installed as part of the
circuit that supplies the SPC Series unit .
6 . Refer to Table 250-122 of the NEC to select the appropriate size
of the grounding conductor . This grounding conductor is to be
grounded to earth at the service equipment or other acceptable
building earth ground such as the building frame in the case of a
high steel-frame structure .
4.1 Mounting
IMPORTANT
ALL CONNECTIONS IN THIS PROCEDURE MUST BE MADE IN ACCORDANCE
WITH NEC, CEC, STATE, COUNTY AND LOCAL CODES FOR ALL SAFETY RAT-
INGS.
TO ENSURE MAXIMUM EFFECTIVENESS AND PROVIDE THE BEST POS-
SIBLE PROTECTION FOR SENSITIVE ELECTRICAL EQUIPMENT, MOUNT IN
SUCH A WAY AS TO MINIMIZE THE CABLE LENGTH AND ELIMINATE ANY
SHARP BENDS IN THE WIRING CONDUIT. SEE FIGURE 2.
WHEN USING CONDUIT, AVOID USING 90° ELBOWS AND KEEP THE CON-
DUIT RUN AS SHORT AND STRAIGHT AS POSSIBLE. SEE FIGURE 3.
