Question: Hello,I plan on installing a subpanel off of a 200 amp 240/120 volt service. I plan on running 100 amps to a subpanel with feed thru lugs. Off of the feed thru lugs of the subpanel, I plan on running a feeder to a 2nd subpanel in a different location on 2nd floor. The feeder will be sized #4 awg (for residential) My question is: Does the code prohibit linking to subpanels together using feed thru lugs? Thank you.
Yes, the code prohibits linking subpanels together using feed-through lugs.
NEC 408.22 states:> "Each subdistribution panelboard shall be individually supplied by a feeder circuit."This means that each subpanel must have its own dedicated feeder. It is not permissible to connect subpanels together in series or parallel using feed-through lugs. Flag for review
