General Order 128
Section I
General Provisions
14 Limiting Conditions Specified
The requirements specified in these rules as to spacing, clearance,
and strength of construction are limiting conditions expressed as minimum
or maximum values as indicated. In cases where two or more requirements establish
limiting conditions the most stringent condition shall be met, thus providing
compliance with the other applicable conditions. Greater strength of construction
and more ample spacings and clearances than herein specified may be desirable
in some cases and may be provided accordingly if other requirements are not
violated in so doing.
