How to choose
Each row is one wire combination; pick your row, then the number of poles.
- Connection: Box to Box, Box to Stud or Stud to Stud (the lists below).
- Wire: the primary and secondary wire range (AWG/kcmil) or stud size, with the openings or studs per pole in brackets. These copper connectors take copper wire only; the 69000 series has aluminum connectors, for aluminum or copper wire.
- Poles: a 1, 2 or 3 pole block, or an adder pole, which snaps onto a 1, 2 or 3 pole block; adder poles lock together to form as many poles as required.
Ampere ratings are based on NEC Table 310-16 for 75 °C copper wire.
SCCR: short-circuit current rating 100 kA with a correctly sized fuse, except adder blocks.
A * after a wire range: copper wire only.
Notes: Not UL/CSA = not UL Recognized or CSA Certified; Double width = a 1 pole block 5.31" wide; Triple width = 7.81" wide.
