(1) The following additional insulation data shall be included on each master drawing or on a
separate insulation master drawing previously approved by the bureau or agency con-
cerned. If the data are shown on a separate insulation master drawing covering insula-
tion practice for a number of motors, the bureau or agency concerned drawing of the in-
sulation master drawing can be referred to on each applicable motor master drawing sub-
ject to the following:
a. A manual is being supplied for the driven equipment and a copy of both the motor and
insulation master drawings are included in the manual.
b, When a manual is not being supplied for the driven equipment, reference to the insula-
tion master drawing on the motor master drawing will be permitted provided the
insulation drawing is furnished with the master drawing.
(2) These additional data, together with the information required by (j) and (k) shall completely
describe all insulation used, indicating the materials, dimensions, forms, sequence of
