Question:
Hi CQD. When figuring box fill, how would you calculate the use of “Polaris lugs” or “split bolts” in the volume calculations? Thanks in advance, Jeremy Buxman

Answer:
Hello Jeremy, great question. Both “Polaris Lugs” and “Split Bolts” are listed as Wire Connectors. The
NEC® does not require an additional volume fill value for wire connectors. However, Sections 314.24 and 314.71 contain general rules for Pull and junction boxes and handhole enclosures that require approved space and dimensions for the installation of conductors and equipment without the likelihood of damage to the conductors within the box.
