# 314.28 Pull and Junction Boxes and Conduit Bodies.
Boxes and conduit bodies used as pull or junction boxes
shall comply with 314.28(A) through (E).
> [!exception]
> Terminal housings supplied with motors shall comply with
> the provisions of 430.12.
## (A) Minimum Size.
For raceways containing conductors of 4 AWG or larger that are required to be insulated,
and for cables containing conductors of 4 AWG or larger,
the minimum dimensions of pull or junction boxes installed in a raceway or cable run
shall comply with 314.28(A)(1) through (A)(3).
Where an enclosure dimension is to be calculated based on the diameter of entering raceways,
the diameter shall be the metric designator (trade size)
expressed in the units of measurement employed.
### (1) Straight Pulls.
In straight pulls,
the length of the box or conduit body
shall not be less than eight times the metric designator (trade size)
of the largest raceway.
### (2) Angle or U Pulls, or Splices.
Where splices or where angle or U pulls are made,
the distance between each raceway entry inside the box or conduit body
and the opposite wall of the box or conduit body
shall not be less than six times the metric designator (trade size)
of the largest raceway in a row.
This distance shall be increased for additional entries
by the amount of the sum of the diameters of all other raceway entries
in the same row on the same wall of the box.
Each row shall be calculated individually,
and the single row that provides the maximum distance shall be used.
> [!exception]
> Where a raceway or cable entry is in the wall of a box or conduit body
> opposite a removable cover,
> the distance from that wall to the cover
> shall be permitted to comply with the distance required
> for one wire per terminal in Table 312.6(A).
The distance between raceway entries enclosing the same conductor
shall not be less than six times the metric designator (trade size)
of the larger raceway.
When transposing cable size into raceway size in 314.28(A)(1) and (A)(2),
the minimum metric designator (trade size) raceway
required for the number and size of conductors in the cable shall be used.
### (3) Smaller Dimensions.
Listed boxes or listed conduit bodies
of dimensions less than those required in 314.28(A)(1) and (A)(2)
shall be permitted for installations of combinations of conductors
that are less than the maximum conduit or tubing fill
(of conduits or tubing being used)
permitted by Table 1 of Chapter 9.
Listed conduit bodies of dimensions less than those required in 314.28(A)(2),
and having a radius of the curve to the centerline
not less than that indicated in Table 2 of Chapter 9
for one-shot and full-shoe benders,
shall be permitted for installations
of combinations of conductors
permitted by Table 1 of Chapter 9.
These conduit bodies shall be marked
to show they have been specifically evaluated
in accordance with this provision.
Where the permitted combinations of conductors
for which the box or conduit body has been listed
are less than the maximum conduit or tubing fill permitted by Table 1 of Chapter 9,
the box or conduit body shall be permanently marked
with the maximum number and maximum size of conductors permitted.
For other conductor sizes and combinations,
the total cross-sectional area of the fill
shall not exceed the cross-sectional area
of the conductors specified in the marking,
based on the type of conductor identified
as part of the product listing.
> [!info]
> Unless otherwise specified,
> the applicable product standards evaluate the fill markings covered here
> based on conductors with Type XHHW insulation.
## (B) Conductors in Pull or Junction Boxes.
In pull boxes or junction boxes having any dimension over 1.8 m (6 ft),
all conductors shall be cabled or racked up in an approved manner.
## (C) Covers.
All pull boxes, junction boxes, and conduit bodies
shall be provided with covers compatible with the box or conduit body construction
and suitable for the conditions of use.
Where used, metal covers shall comply with the grounding requirements of 250.110.
## (D) Permanent Barriers.
Where permanent barriers are installed in a box,
each section shall be considered as a separate box.
## (E) Power Distribution Blocks.
Power distribution blocks shall be permitted
in pull and junction boxes over 1650 cm3 (100 in.3)
for connections of conductors where installed in boxes
and where the installation complies with 314.28(E)(1) through (5).
> [!exception]
> Equipment grounding terminal bars shall be permitted in smaller enclosures.
### (1) Installation.
Power distribution blocks installed in boxes shall be listed.
Power distribution blocks installed on the line side of the service equipment
shall be listed and marked "suitable for use on the line side of service equipment" or equivalent.
### (2) Size.
In addition to the overall size requirement in the first sentence of 314.28(A)(2),
the power distribution block shall be installed in a box
with dimensions not smaller than specified in the installation instructions
of the power distribution block.
### (3) Wire Bending Space.
Wire bending space at the terminals of power distribution blocks
shall comply with 312.6.
### (4) Live Parts.
Power distribution blocks shall not have uninsulated live parts exposed within a box,
whether or not the box cover is installed.
### (5) Through Conductors.
Where the pull or junction boxes are used for conductors
that do not terminate on the power distribution block(s),
the through conductors shall be arranged
so the power distribution block terminals are unobstructed following installation.

# Raceway Terms
## "Raceway"
> [!quote] NEC Article 100
> **Raceway.**
> An enclosed channel
> designed expressly for holding wires, cables, or busbars,
> with additional functions as permitted in this _Code_. (CMP-8)
### "Duct"
> [!quote] NEC 310.2 Definitions
> **Electrical Ducts.**
> Electrical conduits, or other raceways round in cross section,
> that are suitable for use underground or embedded in concrete.
> [!info] Duct Bank
> "Duct bank" is not given explicit definition in the NEC,
> however it is used frequently to refer to any group of ducts,
> _even as few as one_, as shown in Figure 310.60(C)(3).
> It is always spelled as two words.
## "Wiring Method"
"Wiring method" is not given explicit definition in the NEC.
> [!quote] NEC 110.8 Wiring Methods
> Only wiring methods recognized as suitable are included in this Code.
> The recognized methods of wiring
> shall be permitted to be installed in any type of building or occupancy,
> except as otherwise provided in this Code.
> [!quote] NEC 300.1(A) All Wiring Installations
> This article covers general requirements
> for wiring methods and materials
> for all _wiring installations_ (emphasis added)
> unless modified by other articles in Chapter 3.
Nor is wiring installation, however by closest definition
it can be assumed premises wiring includes all wiring installations.
> [!quote] NEC Article 100
> **Premises Wiring (System).**
> Interior and exterior wiring,
> including power, lighting, control, and signal circuit wiring
> together with all their associated hardware, fittings, and wiring devices,
> both permanently and temporarily installed.
> This includes
> (a) wiring from the service point or power source to the outlets or
> (b) wiring from and including the power source to the outlets where there is no service point.
Notably, Chapter 3 does not prescribe requirements for _raceway_, but for _wiring installations_.
As such, conduit used for other purposes (e.g. routing beverage tubing) is out of scope.
Raceways used for supporting communications cables _would be_ out of scope,
except for Article 800.110:
> [!quote] NEC 800.110(A)(1) Raceways Recognized in Chapter 3
> Communications wires and cables shall be permitted
> to be installed in any raceway included in Chapter 3.
> The raceways shall be installed in accordance
> with the requirements of Chapter 3.
Raceway is not a wiring method unless it is used to support premises wiring,
which communications cabling is not.
It is not appropriate to say "EMT conduit is a wiring method"
(granted the NEC does use this syntax occasionally),
because a recognized wiring method must include
the wiring, splices, pull boxes, outlet boxes, and supports
necessary of a complete wiring installation,
each of which has countless options.
It may be appropriate to refer to "MC cable" as a wiring method
if you and your audience understand the name as shorthand
for a more specific, standard framework.
## Takeaways
No part of a manufactured cable assembly (e.g. MC cable)
can be considered a raceway.
It is usually incorrect to refer to wiring methods
in the singular (e.g. installed in _a_ wiring method).
