             Subpart B--Construction and Design Requirements
 
Sec. 18.36  Cables between machine components.

    (a) Cables between machine components shall have: (1) Adequate 
current-carrying capacity for the loads involved, (2) short-circuit 
protection, (3) insulation compatible with the impressed voltage, and 
(4) flame-resistant properties unless totally enclosed within a flame-
resistant hose conduit or other flame-resistant material.
    (b) Cables between machine components shall be: (1) Clamped in place 
to prevent undue movement, (2) protected from mechanical damage by 
position, flame-resistant hose conduit, metal tubing, or troughs 
(flexible or threaded rigid metal conduit will not be acceptable), (3) 
isolated from hydraulic lines, and (4) protected from abrasion by 
removing all sharp edges which they might contact.
    (c) Cables (cords) for remote-control circuits extending from 
permissible equipment will be exempted from the requirements of conduit 
enclosure provided the total electrical energy carried is intrinsically 
safe or that the cables are constructed with heavy jackets, the sizes of 
which are stated in Table 6 of Appendix I. Cables (cords) provided with 
hose-conduit protection shall have a tensile strength not less than No. 
16 (AWG) three-conductor, type SO cord. (Reference: 7.7.7 IPCEA Pub. No. 
S-19-81, Fourth Edition.) Cables (cords) constructed with heavy jackets 
shall consist of conductors not smaller than No. 14 (AWG) regardless of 
the number of conductors.
