• Meter installations require a switch or circuit breaker as part of the building
installation.
•The switch or circuit breaker must be marked as the disconnecting device for
the MMU.
• It is recommended that the enclosure be mounted near the disconnecting
device in an area with adequate ventilation.
•The enclosure should not be positioned in a manner that makes it difficult to
operate the disconnecting device.
• Ensure that the CT and voltage lead lengths (and conduit lengths) are capable
of reaching the enclosure from the breaker panel.
• If a suitable mounting location near the load center cannot be found, additional
in-line fuses or circuit breaker may be required in accordance with NEC
regulations.

4.3.2 Drilling Conduit Holes
The bottom panel and lower half of the side panels work best for conduit opening
locations in outdoor single meter enclosures. Select the location the makes wire
installation easiest for the given environment. If the side panels are used, holes
should be centered approximately half an inch from the bottom of the enclosure.
Hole sizes must be appropriate to fittings, and large enough to fit all voltage and
CT wiring (4-7 18 AWG min. wires insulated for 300 V min.). Care should be
exercised to keep drill bit away from components inside the enclosure. UL Type
4X conduit and fittings must be used in order to maintain the outdoor rating
of the enclosure.

4.5 Installation of Current Transformers
WARNING: TO AVOID FIRE, SHOCK OR DEATH; TURN OFF POWER at circuit
breaker or fuse and test that the power is off before installing or servicing current
transformers.
CAUTION: 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. Violation
of the electric code could be punish by a fine or imprisonment.
4.5.1 General Requirements
•Leviton-provided CT leads are approximately 48 inches. 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
overtighten, as this may compress and weaken the conductor.
•Current and voltage inputs must be installed ‘in phase’ for accurate readings
(e.g. CT1 on Line 1, CT2 on Line 2)
• Field wired CT connections are made to the Mini Meter terminal block. The
rated torque for these terminal blocks is 4.4 in-lb, and can be used with solid
and stranded copper wires, at 12-18 AWG.
•Splices on the CT leads must be within the meter enclosure, not inside the
conduit.
4.5.2 Installing solid core CTs
WARNING: TO AVOID FIRE, SHOCK OR DEATH; TURN OFF POWER at circuit
breaker or fuse and test that the power is off before installing or servicing current
transformers.
1. Route CT wires through the conduit if not already done.
2. Trim the wire to the appropriate length to avoid coils of excess wiring.
