I have some 2400V Allen Bradely bolt in contactors that are 18" from the disconnect switch to the bus. On our old draw out contactors you are definitely 24" from the bus.
You need to consider the working distance from the energized conductors, it can be different for some pieces of equipment.
Quite correct. Default data is exactly that... default.
Here is one not too many people think about.
When the back of equipment is labeled assuming it can be accessed from the back while energized, is the same label on the front placed on the back?
On the front label the assumption is the bus structure is towards the back (24", 36" etc.) On the back of the equipment the same bus structure is.... you guessed it ...a lot closer than the front.
