Looking for a code requirment for additional fasteners @ the main service disconnect similar to 384-16(g) for back-fed devices. Was this a code requirment, manufacters requirment or just good practice? Thanks all.
Is this what you were looking for of course this out of the 2002 nec?
It apears that it was moved from 384-16 (G)
but it is the only place in the cod book that say's anything about back fed main breakers. I know that older 100 amp ITE panels, came with this little red retainer clip that was for this very code.
408.16 Overcurrent Protection.(F) Back-Fed Devices. Plug-in-type overcurrent protection devices or plug-in type-main lug assemblies that are backfed and used to terminate field-installed ungrounded supply conductors shall be secured in place by an additional fastener that requires other than a pull to release the device from the mounting means on the panel.
