APPENDIX G
TORQUE LIMITS
G-1.
GENERAL.
This section provides general torque limits for screws used on the DISE and
PDISE systems.
Special torque limits are indicated in the maintenance
procedures for applicable components.
The general torque limits given in this
appendix shall be used when specific torque limits are not indicated in the
maintenance procedure.
These general torque limits cannot be applied to screws
that retain rubber components.
The rubber components will be damaged before
the correct torque limit is reached.
If a special torque limit is not given in
the maintenance instructions, tighten the screw or nut until it touches the
metal bracket; then tighten it one more turn.
G-2.
TORQUE LIMITS.
Table G-1 lists torque limits for circuit breaker lugs. Table G-2 lists dry
torque limits.
Dry torque limits are used on screws that do not have
lubricants applied to the threads.

TORQUE LIMITS FOR CIRCUIT BREAKER LUGS
NOTE
On the M200 feeder center only, torque the main
circuit breaker (200 amp) input lugs to 180 lb-in
(20.3 N.m).
Torque all other circuit breaker
lugs according to wire size connected as follows:
