1. Recommended cable sizes are 167°F (75°C) (THW) wire at 86°F (30°C) ambient. Unless otherwise noted, use copper or
aluminum conductors suitable for at least 75°C.
2. Recommended cables and conduits are based on breaker trip setting sized for the maximum continuous rated current for the
rectifier input and the nominal current for the bypass and output listed in
through
.
3. Conduit size is based on RNC type conduit for bottom input and EMT-type conduit for top input.
4. Emerson recommends that the site planner choose the appropriate cable type based on the particular installation
requirements.
