What is a Package Starter (PS)?

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!

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.

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

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

It generally means (to me) that the starter is provided under the mechanical system scope of supply, rather than by the general or electrical contractor. Pretty common with HVAC equipment and air compressors.
