Space Occupied by Disconnects
Note: Disconnects will occupy space on panel shown by dimensions "K", "L", and M". Wiring space "P" is available when disconnect is installed in the enclosure.
*The disconnect information and space occupied tables based on data supplied by disconnect manufacturer’s bulletins. Hammond Manufacturing not responsible for dimensional accuracy.
  • All Universal series enclosures require one adaptor kit (ordered separately) to adapt the type of disconnect and mechanism to be used.
  • Each brand and type requires a different adaptor kit.
  • Each kit contains an adaptor plate and master door interlocking mechanism.
  • Fully detailed, illustrated instructions included.

1 Wire bend space "P" does not allow cable sizes larger than 350 MCM in an 84.13" tall enclosure when 4 cables per terminal used.
Refer to NATIONAL ELECTRIC Code 2005 table 312-6(b) for details.
Wire bend space "P" is compatible with C-H Westinghouse breakers with TA1201NB1 terminals.

Part numbers for Complete Operator Mechanisms include flange mounted handle, flexible shaft and circuit breaker mechanism.
The last digit of the part number denotes the shaft length (F1S03=3' length).
 
  • F,J,K frame Flex-Shafts™ available in 3' to 10' lengths.
  • L,N,R frame Flex-Shafts™ available in 4' to 6' lengths.
  


Space Occupied By Disconnect
1. Flex-Shaft™ System permits circuit breaker locations separate from flange mounted handle mechanism.
2. See National Electrical Code 2005 article 430-10(b) for wiring space (Ref “P”) required for line side conductors.
3. Select shaft length based on location of circuit breaker in the enclosure. Maintain a 4" minimum bending radius for the Flex-Shaft™.
4. Space occupied by circuit breaker is calculated by:

 
  • Overall (Height "X" and Width "Y")
  • Minimum wire bend space (manufacturer specified)
  • Location "M" from right to left.
