3.2.2 Making Conduit Holes
Steel (Indoor) Enclosure
The Series 3300/3500 steel enclosure comes with several 1 1/16” knockouts (3/4”conduit). Remove
as needed to connect conduit fittings. Reference voltage and CT connections should enter in lower
half of enclosure.
Outdoor Plastic Enclosure
The bottom, top, and non-hinge side of the plastic enclosure can be used as the conduit location
in outdoor single meter enclosures. Reference voltage and CT wires should enter in lower half of
enclosure. If used, communication wires should enter in top-left of enclosure. Conduit openings
should be as far away from inner components as possible for the installation. Opening sizes must
be appropriate to fittings, and large enough to fit all voltage and CT wiring. Keep drill bit away from
components inside the enclosure. Remove shavings from enclosure after drilling conduit holes.
3.2.3 Mounting Procedure and Conduit Installation
1. Fasten the enclosure to the selected surface using the mounting holes and appropriate screws.
There are mounting holes on both top and bottom of each enclosure. See Figures 3 and 4 for
mounting dimensions.
2. Upon mounting verify that the enclosure is not loose and that all connections are secure.
3. Attach the conduit between enclosure and distribution panel, routing wires as necessary for later
use. For outdoor enclosures UL Type 4X conduit and fittings must be used in order to maintain
the outdoor rating of the enclosure.
4. Ensure conduit fittings are aligned properly and tightened securely to prevent moisture from
entering the enclosure (outdoor applications).

3.3 Installation of Voltage Lines
WARNING: Check to ensure service is disconnected before any connections are made.
Verify if additional in line fuses are required based on National and Local electrical codes.
1. The Series 3300/3500 meter is compatible with both 3-phase 3-wire (no-neutral) and 3-phase
4-wire systems. The meter derives power from the Line 1 and Line 2 voltage connections, which
must be between 177 and 552V for the meter to work properly. Field wired voltage connections
are made to the Series 3300/3500 voltage terminal block. The rated torque for these terminal
blocks is 12 in-lb., and can be used with 14 AWG solid or stranded copper wires.
2. Connect 600 V min. insulated wiring for Line voltages and Neutral to the appropriate locations
in the breaker panel, in accordance with all national and local electrical codes; see Hookup
Diagrams in Figures 8 and 9 below for correct wiring information.
3. Route wires through the conduit if not already done.
4. Trim the wire to the appropriate length to avoid coils of excess wiring.
5. Connect additional in line fuses if required.
6. For connections to the Series 3300/3500 pulse outputs: Route wiring through the top of the
enclosure. Strip wiring to approximately .300 inches and connect to the appropriate terminals.
Wires should be tightened so that they are held snuggly in place, but do not to over-tighten, as
this may compress and weaken the conductor.

3.4 Variations and Installation of Current Transformers
WARNING: Always open or disconnect the circuit from the power distribution system of a
building before installing or servicing current transformers to reduce risk of electric shock.
WARNING: In accordance with NEC, CTs may not be installed in any panel board where they
exceed 75% of the wiring space of any cross-sectional area.
General Requirements:
• Splices on the CT leads must be within the meter enclosure, not inside the conduit. Leviton
provided CT leads are 48 inches minimum. Wire insulation should be stripped so that the bare
conductor length that connects to the meter terminal block does not exceed 0.300 inches.
• CTs should be securely fastened such that they will not slide down to live terminals.
• Wires should be tightened so that they are held snuggly in place, but do not to over-tighten, as this
may compress and weaken the conductor. Maximum rated torque for CT terminal blocks is
4.4 in-lb.
• Current and voltage inputs must be installed in phase‘ (e.g. CT1 on Line 1, CT2 on Line 2, CT3 on
Line 3) and oriented correctly as shown in Hookup Diagrams in Figures 8 and 9.

CT Installation Procedures
1. Route CT secondary wires through conduit if not already done.
2. Trim the wire to the appropriate length to avoid coils of excess wiring.
3. Strip wiring to approximately .300 inches.
4. Connect the CT leads to the appropriate terminals; see Hookup Diagrams in figures 8 and 9
below for correct CT orientations and connections. The CT terminal block is removable to make
wire connections easier; see Figure 5. After securing CT wires to the appropriate terminals slide
terminal block up into header until fully seated.
5. For Split Core CTs: Remove two thumb nuts (Figure 6) and remove section from CT. With
power to the conductors turned off, place the 3-sided section of the CT around the appropriate
conductor while ensuring that white label, white dot or H1 faces Line (source). Reassemble the
CT while ensuring that the white hash marks align (figure 5) and reinstall thumb nuts. Repeat for
remaining conductors for two or three phase applications, as shown in Figures 8 and 9.

3.5 Securing the Enclosure
The outdoor enclosure ships with a padlock and key for securing the door after installation is
complete. The indoor enclosure has a captive screw for securing the enclosure door.
3.6 Turning Power On and Checking for Correct Functionality
3.6.1 Mounting Location
1. After installation is completed and enclosure has been secured the meter may be energized at
the disconnect switch, upon which the meter will go through a power up sequence as described
in Section 4.3. It is strongly advised that users of this product read Section 4 below for a
complete description of meter functionality and displayed values.
2. Several diagnostic tools built into the Series 3300/3500 meter that should be utilized to ensure
the meter and CTs are installed correctly and functioning properly:
a. Energy Flow arrow – Indicates direction of energy flow‘ on amperage and kW screens.
b. For mono-directional metering applications the Energy Flow arrow should always point
to the right. If an Amperage or kW screen shows the arrow pointing to the left a current
transformer may be installed backwards or on the wrong phase, or CT connections at
the meter may be reversed or connected to the wrong CT input terminals, or voltage
wires at the meter could be cross-phased. Section 4 further describes how the Amperage
screens operate to indicate a reverse energy condition. Refer to Hookup Diagrams in
Figures 8 and 9 for correct wiring and CT orientations.
