What is a Package Starter (PS)?

[raar]

Hi, i've recently stumbled across a drawing set that includes mechanical schedules with motor starting types and some include the "PS" abbreviation. Looking at the abbreviation page that stands for package starter. I have basic familiarity with VFD, electronic soft starters, auto-XFMR, WYE-DELTA starters, and across-the-line (motor contactors) but have not come across the PS term before.

The system in this case is an energy recovery ventilator seemingly including supply/exhaust fan(s).

Could someone please explain what a PS starter may be? Thank you for any assistance related to this!

Possibly a bucket in an MCC.
Alternately a combination disconnect and starter. AKA combination starter.
Does that fit your context?

It is an uninformed mechanical engineer’s term for a combination starter, ie one that comes in a box with a breaker, control switches and lights. As in “all in one package”. I’ve run across this before, it’s an HVAC thing.

Thank you for replies @waross and @jraef, I suppose the abbreviation makes sense, but not overly helpful.
