Notes:
1. Optional non-fused disconnect and circuit breaker.
2. Copper wire only, based on nameplate minimum circuit ampacity (MCA).
3. Standard condensing temperature option refers to entering condenser water temperatures 95°F (35°C) and below.
4. Circuit two information is the same as circuit one unless listed on a separate line below circuit one values.
5. XL - across-the-line starter and YD - wye-delta starter.
(a) Will accept 2 conduits per phase in this size.
(b) Will accept 3 conduits per phase in this size.
