hey all-
given-
400A multi meter service (5 suites)
proposed-
48kw generator, 200A standby panel w/5 100a breakers, 5 (2 lug) transfer switches.
question-
can a single generator serve 5 meters and still not be configured as a separately derived source?
(doesn't this mean there is more than one electrical system being backed up by a common power source. and to properly back-up portions of each utility service, the installation would require 5 transfer switches-If the transfer switches had solid neutrals, each system would have two grounding paths. To
avoid this scenario, shouldn't the transfer switch have a switchable neutral pole to maintain the single path to ground? )
what section in the 2017 nec would/does this violate?
let me know your thoughts.thanks!
