1. Recommended cable sizes are 167°F (75°C) (THW) wire at 86°F (30°C) ambient.
2. Refer to NEC recommendations for 104°F (40°C) ambient rated conductors.
3. Unless otherwise noted, use copper or aluminum conductors suitable for at least 75°C.
4. 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 Tables 14 through 17.
5. Conduit size is based on RNC type conduit for bottom input and EMT-type conduit for top input.
6. Vertiv® recommends that the site planner choose the appropriate cable type based on the particular installation requirements.
7. These recommendations are for use with 100% rated breakers. For 125% rated breakers, refer to the NEC recommended conduit and cable sizes.
8. Upstream and downstream non-standard recommended breaker settings have their trip adjustment behind a suitable cover in accordance with
240.6(c) of the NEC.
