WARNING
As a result of the connected loads, high leakage current is possible. Connection to earth ground is required for
safety and proper product operation. Do not check IAC-D operation by any action that includes removal of the
earth (ground) connection with loads attached.
•
Refer to national and local electrical codes for acceptable external wiring practices.
•
For external wiring, use copper wire with 75°C rated insulation. Wire sizes listed in
through
are for copper wiring only. If wire is run in an ambient temperature greater than 40°C (104°F), higher
temperature wire and/or larger size wire may be necessary. Wire sizes are based on using the specified
breakers.
•
Recommended wire sizes are based on NFPA National Electrical Code

•
Refer to NEC Article 250 and local codes for proper grounding practices.
•
Per NEC Article 300-20(B), all three-phase conductors must be run in the same conduit. Neutral and ground
must be run in the same conduit as the phase conductors.
•
Conduit is to be sized to accommodate three phase conductors, one neutral conductor the same size as
the phase conductors and one ground conductor. If two neutral conductors or an oversized neutral
conductor are to be installed, size the conduit to accommodate the extra wire or size.
