UPS connection common neutral supply & load

[Lucien Nunes]

Possibly, although the way I read it the essential circuits are PLC power supplies built into a panel and that they weren't fed from a DB as such. If their OPD is in the panel too then it's just a question of segregating the neutrals but as you say it might be best to run them out to a new DB.

Hi Guys

Very sorry for not replying must be my forum settings are not set correctly yet for receiving notification, many thanks for the reply's & yes it is a huge chiller control panel that was engineered in case of failures by even splitting the Neutrals on the same CCT instead of daisy chaining them, yes you have confirmed for me I am going to have separate the ccts on the PLC cct i wish to protect & install another Neutral block on the load side of the UPS.

thanks
