I’m planning to replace my old central forced air HVAC with mini split systems, but for a number of reasons, it will be more than a single multi-zone compressor. In that regard, am I required to have a dedicated branch circuit to each compressor, or can I run a single (appropriately sized) branch circuit to two or more compressors (assuming each one has its own disconnect)?
The main reason for this is the lack of room left in my breaker panel, and each unit typically requires two poles (the most efficient units are 240 V). It also makes the wiring effort easier.
Even if each unit has a rated maximum service breaker, it seems a disconnect with a breaker in it would address this, right?
