3.5 Installation Instructions
•
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.
3.5.2 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.
Type 4X
conduit and fittings must be used in order to maintain the outdoor rating of
the enclosure.
3.5.3 Mounting Procedure and Conduit Installation
1. Attach the mounting brackets to the back of the enclosure with the four
provided screws as shown in Figure 6.
2. Fasten the enclosure to the selected surface via mounting holes.
3. Verify that the enclosure is not loose and that all connections are secure.
4. Attach the conduit between enclosure and load center, routing wires as
necessary for later use.
5. Make sure the conduit fittings are aligned properly and tightened securely to
prevent moisture from entering the enclosure (outdoor applications).
