the wiring.

Remove the rubber bushings from the holes to be used for wiring with conduits, and then fit conduits
into the holes.

If a cable is connected through the plate hole without a rubber bushing and conduit, the cable
insulation may be damaged by the edge of the hole, resulting in a short circuit or ground fault.
