To install panel mounted camlocks for standard entertainment industry connections, I don't see any relief from cutting slots between the conductors passing through the ferrous enclosure wall.
Of course that wall section can be replaced with an insulating or non-ferrous panel, but that doesn't seem to actually happen much, or at least I've never seen it.
Has anyone witnessed overheating of panel walls from these connectors as they are commonly used?
NEC 300.20 said:...(B) Individual Conductors. Where a single conductor carrying alternating current passes through metal with magnetic
properties, the inductive effect shall be minimized by (1) cutting slots in the metal between the individual holes through which the individual conductors pass or (2) passing all the conductors in the circuit through an insulating wall sufficiently large for all of the conductors of the circuit.
