CAUTION: JSP’s performance will be limited severely if the
conductors are (a) too long, (b) are of too small a wire gauge, (c) have
too many bends or (d) have sharp bends. For optimum performance
never exceed 10' conductor lengths.
Figure 5
3-Phase, 4-Wire High-Leg Delta
Conductor Sizing and Routing
If bends are required, they should be sweeping bends (12" radius). Do not make
sharp 90° bends for appearance purposes because they will severely decrease
the effectiveness of the JSP unit.
Binding or twisting conductors together using tiewraps or electrical tape
increases the protection performance of the device.
Joslyn recommends installing the JSP unit by following conductor size for
phase, ground and neutral connections. The conductor length should be as
short as possible to ensure the maximum level of protection.

Upstream Overcurrent
Protection Device
CAUTION: Careful consideration must be made when selecting
an area for conduit entry. There are several components inside the
enclosure that may interfere with the conduit entry path, therefore,
ensure the path is clear of all objects before drilling. Damages caused
by installation errors are not covered under the product warranty.
See Figure 6 for conduit openings and enclosure dimensions.
Mounting
Indoor vs. Outdoor Installations
Conduit Openings
Mount the JSP to the building structure using construction methods and
hardware appropriate for your site. Install the conduit and pull the conductors
as specified in Table 2.
NEMA 4 enclosures are suitable for indoor or outdoor use. NEMA 4X (stainless
steel) enclosures are suitable for corrosive environments as well. For direct
sunlight applications, Joslyn suggests shading the monitoring components.
All conduits and fittings must be rated and properly installed so that the final
installation maintains the NEMA rating.
If desired, punch holes at this time for the conduit or nipple or wait until the
JSP is mounted to the building structure. Punch holes only in the designated
areas as shown in the following illustration.
The JSP is a Type 1 SPD which is suitable for use in both Type 1 and Type
2 SPD applications. The JSP is a one-port SPD and is to be connected in
parallel with the electrical system. It may be connected via a circuit breaker,
molded case switch, fused switch, or connected directly to the bus of the
panelboard or switchboard it is protecting. If direct bus connection is used,
Joslyn® recommends installing the JSP behind a disconnect switch or other
disconnecting means for ease of serviceability.
If the SPD is connected to a dedicated OCPD, a 60A breaker is recommended
(30A minimum, 200A maximum).

Conduit Openings and
Enclosure/Mounting
Dimensions
Electrical Connections
Following all applicable National Electrical Code standards as well as state and
local codes, connect phase, neutral* and ground to JSP. The 60kA, 80kA and
100kA units come with 36" of #10AWG conductors. Each phase conductor is
labeled (Phase A, B or C). The 120kA, 160kA, 200kA, 240kA, 300kA and 400kA
units come with compression box lugs. The installer must provide the appropriate
conductors. Ensure that the conductor lengths are kept as short and straight
as possible. On all high-leg delta systems, the high-leg (208V LN) must be
connected to the Phase B of the SPD. (Color coded orange according to NEC).
*The 3-Wire + Ground Delta JSP does not have a neutral conductor.

Contacts shown in de-energized state
(alarm condition).
Figure 8
Terminal Block
Contacts shown in energized normal state
(no fault condition).
Units that come with Form “C” dry relay contacts provide status of the surge
protective device. These contacts are for connection to a user-provided remote
alarm and monitoring circuit. The relay contacts are rated 65VDC/150VAC with
maximum switching power of 30WDC/60VA AC.
When input power is present on all phases, terminals “NO” (Normally Open)
and “COM” (Common) are an open circuit and terminals “NC” (Normally Closed)
and “COM” are a closed circuit. The contacts change state when the unit has
encountered failure to one or more phases.
The installer must provide the appropriate raceway and wiring for the monitoring
circuit, observing the restrictions and conduit openings illustrated in an earlier
section of this manual.
Models: JSP120kA to JSP400kA
For these models, the Form “C” contacts must be wired by the installer.
See Figure 8 for the Form “C” contact configuration and terminal location on
the monitor board. The annotations on the diagram match the markings on the
terminal block.
The installer must route the monitoring conductors to the terminal blocks on
the door mounted main monitoring board. Route the wires to allow the door
to be opened and closed properly. Tighten screws on terminals to 3.5 in-lbs.
(0.4 Nm). This terminal block will accept wire sizes #28AWG–#16AWG.
#18–#20AWG is recommended.
Models: JSP60kA to JSP100kA with -M option
For these models, the Form “C” contacts come pre-wired with 36" of #20AWG
conductors.
See Figure 7 for the Form “C” wiring and contact configuration.
Use butt splices within the panelboard to connect the Form “C” leads to the
user’s monitoring circuits. Alternatively, install a junction box between the JSP
and the panelboard to connect Form “C” leads to user’s monitoring circuits.
If the Form “C” contacts are not used, user has the option of either cutting
off the leads or coiling up the leads and saving them for potential future use.
Consult applicable local codes to ensure proper installation.
