KOs in boxes manufactured today are listed as suitable for grounding means and are not required to have additional bonding means, over or under 250 volts. Take a look at BGUZ for junction boxes and QCIT for outlet boxes.Make it a junction or device box and the box must be connected to the grounding .
Can the branch circuit equipment grounding conductor be bonded to the box and then extended out to be spliced to the other equipment .
Make it a junction or device box and the box must be connected to the grounding conductor. Re: GROUND SCREWS IN METAL JUNCTION BOXES Section 250.118 lists the . 250.4 (A) (2), (3), & (4) says that " Normally noncurrent-carrying conductive materials enclosing electrical conductors or equipment " should be grounded and bonded. So . KOs in boxes manufactured today are listed as suitable for grounding means and are not required to have additional bonding means, over or under 250 volts. Take a look at BGUZ for junction boxes and QCIT for outlet boxes.
Can the branch circuit equipment grounding conductor be bonded to the box and then extended out to be spliced to the other equipment grounding conductor(s) and equipment bonding jumper to the wiring device? The information provided below is based on the 2020 edition of the National Electrical Code.
If the junction box has metal parts not intended to carry current, you must bond these parts to the grounding system. The grounding conductor must be continuous and unspliced. It must also be sized according to the size of the junction box.
Equipment grounding is the connection to the ground of non-current-carrying conductive materials – e.g., cable trays, metallic conduits, junction boxes, transformer casings, and motor frames. The purpose is to limit the conductive material voltage to the ground. Make it a junction or device box and the box must be connected to the grounding conductor. Re: GROUND SCREWS IN METAL JUNCTION BOXES Section 250.118 lists the allowed equipment grounding (bonding) conductors, .
250.4 (A) (2), (3), & (4) says that " Normally noncurrent-carrying conductive materials enclosing electrical conductors or equipment " should be grounded and bonded. So while you may not have to connect the equipment grounding conductor to the box, the boxes do have to be grounded and bonded.Code Change Summary: Revised code section on the installation requirements for conductors in boxes and conduit bodies. In the 2020 NEC ® , the requirements previously found in 314.17(B) and (C) were combined into a revised Section 314.17(B). Typically a junction box either contains splices on the energized conductors (thus requiring that the box be individually bonded with a pigtail connected to the EGC), or the box is simply a pull-through point (thus not requiring the box to be bonded individually with a pigtail). A connection shall be made between the one or more equipment grounding conductors and a metal box by means of a grounding screw that shall be used for no other purpose, equipment listed for grounding, or a listed grounding device.

The rules for pull boxes, junction boxes, and outlet boxes cover five areas. In summary: Minimum size [314.28(A)]. These requirements constitute most of Sec. 314.28. One key point is that on straight pulls the box or conduit body length must be at least eight times the trade size of the raceway.
