We request your advice and feedback for the below query.
We have 110V AC electrical distribution circuit (with Phase, Neutral & Ground) for office building with low power lighting and electrical sockets.
Our query is, what is the maximum allowable Voltage between Neutral & Ground point?, Is there any Standard Reference for this?
We have searched in NFPA70 (2014) and we could not direct answer to our query, however could find related section under NEC Article 210.19 (A) Note-4 as attached with red box. Request for your kind support, is this Article is related to our query or any Article is available under NFPA?
