Information
The location and size of the bottom shall cover the area shown in Figure 3-1. Any part of
the side which is within the area traced out by the 5° angle is also considered to be part
of the bottom of the fire enclosure.
Figure 3-1 Fire enclosure bottom layout
The bottom, including the part of the side considered to be part of the bottom, must be
designed to prevent escape of burning material - either by having no openings or by
having a baffle construction. This means that openings for cables etc. must be sealed
with materials meeting the 5VB requirement, or else have a baffle above.
See Figure 3-2 for acceptable baffle construction. This does not apply for mounting in
an enclosed electrical operating area (restricted access) with concrete floor.
