If the box is metal, add a pigtail—a 6-inch length of the same type of ground wire—to the ground wire connection, then connect the loose end of the pigtail to the ground screw on the box. Special green wire nut connectors are generally used to .

Anyone know if the workspace requirements of 110.26 apply to pull . You must size pull boxes, junction boxes, and conduit bodies large enough so a crew can install the conductors without damaging them. For . Anyone know if the workspace requirements of 110.26 apply to pull boxes where the pull box has not taps or live energized parts. Just cabling passing through and used as a .
Electrical Conduit pull boxes provide access to successfully pull wires through metallic or non-metallic conduit & raceways. This article describes the requirements for pull-boxes including sizing & spacing or distances .
Consider installations where there are no energized, exposed live parts to be worked on when maintenance or repair work is in progress. A good example is a junction box . Use 314.28 (A) to size pull boxes, junction boxes, and conduit bodies when using conductor sizes 4 AWG and larger. Suppose you have a 2-inch raceway coming into a 10-inch square box, and a 2-inch raceway leaves . What clearance is required for ready and safe maintenance would depend on a number of factors and is a judgement call. I would suggest that you talk it over with the AHJ. 110.26 says minimum 3 feet. 110.26 does not say you need 3' . 110.26 (A) Working Space.
Section 110.26 specifies the requirements for the clearance area around electrical equipment, including junction boxes. Section 110.26(A) requires a clear space of at least 30 inches wide by 36 inches deep. You must size pull boxes, junction boxes, and conduit bodies large enough so a crew can install the conductors without damaging them. For conductors 4 AWG and larger, you size pull boxes, junction boxes, and conduit bodies per Sec. 314.28. That means the minimum dimensions of boxes and conduit bodies must comply with the following:
Anyone know if the workspace requirements of 110.26 apply to pull boxes where the pull box has not taps or live energized parts. Just cabling passing through and used as a pull point. If there are no workspace requirements in the .
Electrical Conduit pull boxes provide access to successfully pull wires through metallic or non-metallic conduit & raceways. This article describes the requirements for pull-boxes including sizing & spacing or distances between pull boxes & their locations. Consider installations where there are no energized, exposed live parts to be worked on when maintenance or repair work is in progress. A good example is a junction box installed in an attic with no working space or clearance space required by . Use 314.28 (A) to size pull boxes, junction boxes, and conduit bodies when using conductor sizes 4 AWG and larger. Suppose you have a 2-inch raceway coming into a 10-inch square box, and a 2-inch raceway leaves it on the opposite side. Crawlspaces and especially above ceiling space electrical installations can now be provided with working clearances according to prescriptive requirements, which will lead to better safety for electricians and maintenance workers.
However, we are using electrical metallic tubing (EMT), and one engineer has informed us that all of the rules in NEC Chapter 3 for raceways, including boxes, apply. Do the rules for sizing a pull box in 314.28 apply because we are using EMT?

white paper series seeks to outline “clearance” requirements found in NFPA 70-2020 (NEC) for the installation of the following pieces of low voltage (1,000 volts or less) electrical distribution equipment: • Panelboards. • Switchboards. • Dry-type transformers. • Enclosed switches (aka “safety switches”). Equipment “Clearances”

The appropriate wire used for a junction box is typically an enclosed Romex wire that runs through the sub-panel or main electrical panel. This wire is commonly color-coded, with black denoting heat, white serving as the neutral channel, and copper or green wire used for grounding the connection.
