nuetral question

[fearfakter]

hi

Can nuetrals be tied together from multiple transformers
in normal step down levels, like all 1440 volt levels and all 480 volt
levels respectively in Y systems. delta systems?
both, all and different voltage levels safely. If they can is it common
practise?

If they are all to be solidly grounded systems, they are all, in essence,
bonded together. If you are not bonding them to ground, what is point?

For the voltage levels you list, neutrals are commonly bonded to ground. It
is safe and it is common practice.

Neutrals are generally bonded to ground at the transformer or at the service
entrance equipment (or the secondary protection equipment for the
transformer).

If you want to bond them somewhere else, (such as taking the neutrals from
transformers all across a large site and bonding them at a central
location) that may be unsafe.

Thank you for your responce. i am not up on distribution
like I should be.
