so that such additions or conversions are simple

time or skill on the part of the operator.
Special instructional drawings are �vailable
which will further simplfy the addition of such
accessories to breakers which were originally
shipped without them.

will also be available upon request, The drawings
and the accessory additions which they cover are
listed below.

is recommended that the section of instructions
contained herein covering that particular accessory
