• There are numerous methods for making wire entry holes in the enclosure but it
is imperative that no loose material generated during the process remains in the
enclosure. During installation and cutting the wire holes, all equipment mounted
inside or on the enclosure shall be protected from loose material.
• No matter what procedure is used the installer shall verify that the hole cutting
process will not damage any of the wiring or components installed inside or on
the enclosure.
a. The two recommended procedures for cutting the wire entry holes are as
follows:
• Use a "C" frame punch to cut the wire entry holes. This type of punch
does not require a pilot hole. A typical "C" frame punch is shown below.

• Regular punch:
1. Place a magnet inside the enclosure where the pilot hole is to be cut
and completely cover the area with masking tape (or other very
sticky tape).
2. Drill the pilot hole from the outside and do not let the drill pass more
than ¼" into the enclosure.
3. Remove the tape, magnet, and cuttings and punch the hole.
