LEARNING EVENT 1:
The selection of a point of entrance is dependent upon the locations of the telephone, the
protector or connecting block, and the exterior and interior wire runs. Before selecting a point of
entrance, survey the building premises for the location of the above-mentioned apparatus. A point of
entrance for a masonry or stucco-on-masonry building can be a window or door frame (except for a
metal door frame). On a frame or stucco-on-frame building a point of entrance can be established
immediately above or through the foundation sill. If the entrance hole is made through the foundation
sill, be sure to clear all joists and studs. See Figure 46.
